 # Forgejo Configuration
 This directory contains configuration files for Forgejo (self-hosted Git service).
 ## Pull Request Template
 The `pull_request_template.md` is automatically loaded when creating a new Pull Request. It provides a checklist and instructions for the PR workflow, including how to run the full test suite before merging.
 ## Branch Protection Setup
 To enforce the full test suite before merging to `main`, configure branch protection in Forgejo:
 ### Steps:
 1. Go to **Repository Settings** → **Branches** → **Protected Branches**
 2. Add a new rule for branch: `main`
 3. Configure the following settings:
   - ☑️ **Enable Branch Protection**
   - ☑️ **Require status checks to pass before merging**
     - Add required check: `check-full`
   - ☐ **Require approvals** (optional, based on team preference)
   - ☑️ **Block if there are outstanding requests** (optional)
 ### What this does:
 - The **"Merge"** button in PRs will only be enabled after `check-full` passes
 - `check-full` is triggered by **promoting** a build in Drone CI (see PR template)
 - This ensures all tests (including slow and UI tests) run before merging
 ## Workflow
 1. **Create PR** → Fast test suite (`check-fast`) runs automatically
 2. **Development** → Fast tests run on every push for quick feedback
 3. **Ready to merge:**
   - Remove `WIP:` from PR title
   - Go to Drone CI and **promote** the build to `production`
   - This triggers `check-full` (full test suite)
 4. **After full tests pass** → Merge button becomes available
 5. **Merge to main** → Container is built and published
 ## Secrets Required
 Make sure the following secrets are configured in Drone CI:
 - `DRONE_REGISTRY_USERNAME` - For container registry
 - `DRONE_REGISTRY_TOKEN` - For container registry
 - `RENOVATE_TOKEN` - For Renovate bot
 - `GITHUB_COM_TOKEN` - For Renovate bot (GitHub dependencies)

 - Mock external services
 - Use fixtures efficiently
 **Performance Tests:**
 Performance tests that explicitly validate performance characteristics should be tagged with `@tag :slow` or `@describetag :slow` to exclude them from standard test runs. This improves developer feedback loops while maintaining comprehensive coverage.
 **When to Tag as `:slow`:**
 - Tests that explicitly measure execution time or validate performance characteristics
 - Tests that use large datasets (e.g., 50+ records) to test scalability
 - Tests that validate query optimization (N+1 prevention, index usage)
 **Tagging Guidelines:**
 - Use `@tag :slow` for individual tests
 - Use `@describetag :slow` for entire describe blocks (not `@moduletag`, as it affects all tests in the module)
 - Performance tests should include measurable assertions (query counts, timing with tolerance, etc.)
 **UI Tests:**
 UI tests that validate basic HTML rendering, Phoenix LiveView navigation, or framework functionality (Gettext translations, form elements, UI state changes) should be tagged with `@tag :ui` or `@describetag :ui` to exclude them from fast CI runs. Use `@tag :ui` for individual tests and `@describetag :ui` for describe blocks. UI tests can be consolidated when they test similar elements (e.g., multiple translation tests combined into one). Do not tag business logic tests (e.g., "can delete a user"), validation tests, or data persistence tests as `:ui`.
 **Running Tests:**
 ```bash
 # Fast tests only (excludes slow and UI tests)
 mix test --exclude slow --exclude ui
 # Or use the Justfile command:
 just test-fast
 # UI tests only
 mix test --only ui
 # Or use the Justfile command:
 just ui
 # Performance tests only
 mix test --only slow
 # Or use the Justfile command:
 just slow
 # All tests (including slow and UI tests)
 mix test
 # Or use the Justfile command:
 just test
 # Or use the Justfile command:
 just test-all
 ```
 **Test Organization Best Practices:**
 - **Fast Tests (Standard CI):** Business logic, validations, data persistence, edge cases
 - **UI Tests (Full Test Suite):** Basic HTML rendering, navigation, translations, UI state
 - **Performance Tests (Full Test Suite):** Query optimization, large datasets, timing assertions
 This organization ensures fast feedback in standard CI while maintaining comprehensive coverage via promotion before merge.

 # Test Performance Optimization
 **Last Updated:** 2026-01-28  
 **Status:** ✅ Active optimization program
 ---
 ## Executive Summary
 This document provides a comprehensive overview of test performance optimizations, risk assessments, and future opportunities. The test suite execution time has been reduced through systematic analysis and targeted optimizations.
 ### Current Performance Metrics
 | Metric | Value |
 |--------|-------|
 | **Total Execution Time** (without `:slow` tests) | ~368 seconds (~6.1 minutes) |
 | **Total Tests** | 1,336 tests (+ 25 doctests) |
 | **Async Execution** | 163.5 seconds |
 | **Sync Execution** | 281.5 seconds |
 | **Slow Tests Excluded** | 25 tests (tagged with `@tag :slow`) |
 | **Top 50 Slowest Tests** | 121.9 seconds (27.4% of total time) |
 ### Optimization Impact Summary
 | Optimization | Tests Affected | Time Saved | Status |
 |--------------|----------------|------------|--------|
 | Seeds tests reduction | 13 → 4 tests | ~10-16s | ✅ Completed |
 | Performance tests tagging | 9 tests | ~3-4s per run | ✅ Completed |
 | Critical test query filtering | 1 test | ~8-10s | ✅ Completed |
 | Full test suite via promotion | 25 tests | ~77s per run | ✅ Completed |
 | **Total Saved** | | **~98-107s** | |
 ---
 ## Completed Optimizations
 ### 1. Seeds Test Suite Optimization
 **Date:** 2026-01-28  
 **Status:** ✅ Completed
 #### What Changed
 - **Reduced test count:** From 13 tests to 4 tests (69% reduction)
 - **Reduced seeds executions:** From 8-10 times to 5 times per test run
 - **Execution time:** From 24-30 seconds to 13-17 seconds
 - **Time saved:** ~10-16 seconds per test run (40-50% faster)
 #### Removed Tests (9 tests)
 Tests were removed because their functionality is covered by domain-specific test suites:
 1. `"at least one member has no membership fee type assigned"` → Covered by `membership_fees/*_test.exs`
 2. `"each membership fee type has at least one member"` → Covered by `membership_fees/*_test.exs`
 3. `"members with fee types have cycles with various statuses"` → Covered by `cycle_generator_test.exs`
 4. `"creates all 5 authorization roles with correct permission sets"` → Covered by `authorization/*_test.exs`
 5. `"all roles have valid permission_set_names"` → Covered by `authorization/permission_sets_test.exs`
 6. `"does not change role of users who already have a role"` → Merged into idempotency test
 7. `"role creation is idempotent"` (detailed) → Merged into general idempotency test
 #### Retained Tests (4 tests)
 Critical deployment requirements are still covered:
 1. ✅ **Smoke Test:** Seeds run successfully and create basic data
 2. ✅ **Idempotency Test:** Seeds can be run multiple times without duplicating data
 3. ✅ **Admin Bootstrap:** Admin user exists with Admin role (critical for initial access)
 4. ✅ **System Role Bootstrap:** Mitglied system role exists (critical for user registration)
 #### Risk Assessment
 | Removed Test Category | Alternative Coverage | Risk Level |
 |----------------------|---------------------|------------|
 | Member/fee type distribution | `membership_fees/*_test.exs` | ⚠️ Low |
 | Cycle status variations | `cycle_generator_test.exs` | ⚠️ Low |
 | Detailed role configs | `authorization/*_test.exs` | ⚠️ Very Low |
 | Permission set validation | `permission_sets_test.exs` | ⚠️ Very Low |
 **Overall Risk:** ⚠️ **Low** - All removed tests have equivalent or better coverage in domain-specific test suites.
 ---
 ### 2. Full Test Suite via Promotion (`@tag :slow`)
 **Date:** 2026-01-28  
 **Status:** ✅ Completed
 #### What Changed
 Tests with **low risk** and **execution time >1 second** are now tagged with `@tag :slow` and excluded from standard test runs. These tests are important but not critical for every commit and are run via promotion before merging to `main`.
 #### Tagging Criteria
 **Tagged as `@tag :slow` when:**
 - ✅ Test execution time >1 second
 - ✅ Low risk (not critical for catching regressions in core business logic)
 - ✅ UI/Display tests (formatting, rendering)
 - ✅ Workflow detail tests (not core functionality)
 - ✅ Edge cases with large datasets
 **NOT tagged when:**
 - ❌ Core CRUD operations (Member/User Create/Update/Destroy)
 - ❌ Basic Authentication/Authorization
 - ❌ Critical Bootstrap (Admin user, system roles)
 - ❌ Email Synchronization
 - ❌ Representative tests per Permission Set + Action
 #### Identified Tests for Full Test Suite (25 tests)
 **1. Seeds Tests (2 tests) - 18.1s**
 - `"runs successfully and creates basic data"` (9.0s)
 - `"is idempotent when run multiple times"` (9.1s)
 - **Note:** Critical bootstrap tests remain in fast suite
 **2. UserLive.ShowTest (3 tests) - 10.8s**
 - `"mounts successfully with valid user ID"` (4.2s)
 - `"displays linked member when present"` (2.4s)
 - `"redirects to user list when viewing system actor user"` (4.2s)
 **3. UserLive.IndexTest (5 tests) - 25.0s**
 - `"displays users in a table"` (1.0s)
 - `"initially sorts by email ascending"` (2.2s)
 - `"can sort email descending by clicking sort button"` (3.4s)
 - `"select all automatically checks when all individual users are selected"` (2.0s)
 - `"displays linked member name in user list"` (1.9s)
 **4. MemberLive.IndexCustomFieldsDisplayTest (3 tests) - 4.9s**
 - `"displays custom field with show_in_overview: true"` (1.6s)
 - `"formats date custom field values correctly"` (1.5s)
 - `"formats email custom field values correctly"` (1.8s)
 **5. MemberLive.IndexCustomFieldsEdgeCasesTest (3 tests) - 3.6s**
 - `"displays custom field column even when no members have values"` (1.1s)
 - `"displays very long custom field values correctly"` (1.4s)
 - `"handles multiple custom fields with show_in_overview correctly"` (1.2s)
 **6. RoleLive Tests (7 tests) - 7.7s**
 - `role_live_test.exs`: `"mounts successfully"` (1.5s), `"deletes non-system role"` (2.1s)
 - `role_live/show_test.exs`: 5 tests >1s (mount, display, navigation)
 **7. MemberAvailableForLinkingTest (1 test) - 1.5s**
 - `"limits results to 10 members even when more exist"` (1.5s)
 **8. Performance Tests (1 test) - 3.8s**
 - `"boolean filter performance with 150 members"` (3.8s)
 **Total:** 25 tests, ~77 seconds saved
 #### Execution Commands
 **Fast Tests (Default):**
 ```bash
 just test-fast
 # or
 mix test --exclude slow
 ```
 **Slow Tests Only:**
 ```bash
 just test-slow
 # or
 mix test --only slow
 ```
 **All Tests:**
 ```bash
 just test
 # or
 mix test
 ```
 #### CI/CD Integration
 - **Standard CI (`check-fast`):** Runs `mix test --exclude slow --exclude ui` for faster feedback loops (~6 minutes)
 - **Full Test Suite (`check-full`):** Triggered via promotion before merge, executes `mix test` (all tests, including slow and UI) for comprehensive coverage (~7.4 minutes)
 - **Pre-Merge:** Full test suite (`mix test`) runs via promotion before merging to main
 - **Manual Execution:** Promote build to `production` in Drone CI to trigger full test suite
 #### Risk Assessment
 **Risk Level:** ✅ **Very Low**
 - All tagged tests have **low risk** - they don't catch critical regressions
 - Core functionality remains tested (CRUD, Auth, Bootstrap)
 - Standard test runs are faster (~6 minutes vs ~7.4 minutes)
 - Full test suite runs via promotion before merge ensures comprehensive coverage
 - No functionality is lost, only execution timing changed
 **Critical Tests Remain in Fast Suite:**
 - Core CRUD operations (Member/User Create/Update/Destroy)
 - Basic Authentication/Authorization
 - Critical Bootstrap (Admin user, system roles)
 - Email Synchronization
 - Representative Policy tests (one per Permission Set + Action)
 ---
 ### 3. Critical Test Optimization
 **Date:** 2026-01-28  
 **Status:** ✅ Completed
 #### Problem Identified
 The test `test respects show_in_overview config` was the slowest test in the suite:
 - **Isolated execution:** 4.8 seconds
 - **In full test run:** 14.7 seconds
 - **Difference:** 9.9 seconds (test isolation issue)
 #### Root Cause
 The test loaded **all members** from the database, not just the 2 members from the test setup. In full test runs, many members from other tests were present in the database, significantly slowing down the query.
 #### Solution Implemented
 **Query Filtering:** Added search query parameter to filter to only the expected member.
 **Code Change:**
 ```elixir
 # Before:
 {:ok, _view, html} = live(conn, "/members")
 # After:
 {:ok, _view, html} = live(conn, "/members?query=Alice")
 ```
 #### Results
 | Execution | Before | After | Improvement |
 |-----------|--------|-------|-------------|
 | **Isolated** | 4.8s | 1.1s | **-77%** (3.7s saved) |
 | **In Module** | 4.2s | 0.4s | **-90%** (3.8s saved) |
 | **Expected in Full Run** | 14.7s | ~4-6s | **-65% to -73%** (8-10s saved) |
 #### Risk Assessment
 **Risk Level:** ✅ **Very Low**
 - Test functionality unchanged - only loads expected data
 - All assertions still pass
 - Test is now faster and more isolated
 - No impact on test coverage
 ---
 ### 3. Full Test Suite Analysis and Categorization
 **Date:** 2026-01-28  
 **Status:** ✅ Completed
 #### Analysis Methodology
 A comprehensive analysis was performed to identify tests suitable for the full test suite (via promotion) based on:
 - **Execution time:** Tests taking >1 second
 - **Risk assessment:** Tests that don't catch critical regressions
 - **Test category:** UI/Display, workflow details, edge cases
 #### Test Categorization
 **🔴 CRITICAL - Must Stay in Fast Suite:**
 - Core Business Logic (Member/User CRUD)
 - Authentication & Authorization Basics
 - Critical Bootstrap (Admin user, system roles)
 - Email Synchronization
 - Representative Policy Tests (one per Permission Set + Action)
 **🟡 LOW RISK - Moved to Full Test Suite (via Promotion):**
 - Seeds Tests (non-critical: smoke test, idempotency)
 - LiveView Display/Formatting Tests
 - UserLive.ShowTest (core functionality covered by Index/Form)
 - UserLive.IndexTest UI Features (sorting, checkboxes, navigation)
 - RoleLive Tests (role management, not core authorization)
 - MemberLive Custom Fields Display Tests
 - Edge Cases with Large Datasets
 #### Risk Assessment Summary
 | Category | Tests | Time Saved | Risk Level | Rationale |
 |----------|-------|------------|------------|-----------|
 | Seeds (non-critical) | 2 | 18.1s | ⚠️ Low | Critical bootstrap tests remain |
 | UserLive.ShowTest | 3 | 10.8s | ⚠️ Low | Core CRUD covered by Index/Form |
 | UserLive.IndexTest (UI) | 5 | 25.0s | ⚠️ Low | UI features, not core functionality |
 | Custom Fields Display | 6 | 8.5s | ⚠️ Low | Formatting tests, visible in code review |
 | RoleLive Tests | 7 | 7.7s | ⚠️ Low | Role management, not authorization |
 | Edge Cases | 1 | 1.5s | ⚠️ Low | Edge case, not critical path |
 | Performance Tests | 1 | 3.8s | ✅ Very Low | Explicit performance validation |
 | **Total** | **25** | **~77s** | **⚠️ Low** | |
 **Overall Risk:** ⚠️ **Low** - All moved tests have low risk and don't catch critical regressions. Core functionality remains fully tested.
 #### Tests Excluded from Full Test Suite
 The following tests were **NOT** moved to full test suite (via promotion) despite being slow:
 - **Policy Tests:** Medium risk - kept in fast suite (representative tests remain)
 - **UserLive.FormTest:** Medium risk - core CRUD functionality
 - **Tests <1s:** Don't meet execution time threshold
 - **Critical Bootstrap Tests:** High risk - deployment critical
 ---
 ## Current Performance Analysis
 ### Top 20 Slowest Tests (without `:slow`)
 After implementing the full test suite via promotion, the remaining slowest tests are:
 | Rank | Test | File | Time | Category |
 |------|------|------|------|----------|
 | 1 | `test Critical bootstrap invariants Mitglied system role exists` | `seeds_test.exs` | 6.7s | Critical Bootstrap |
 | 2 | `test Critical bootstrap invariants Admin user has Admin role` | `seeds_test.exs` | 5.0s | Critical Bootstrap |
 | 3 | `test normal_user permission set can read own user record` | `user_policies_test.exs` | 2.6s | Policy Test |
 | 4 | `test normal_user permission set can create member` | `member_policies_test.exs` | 2.5s | Policy Test |
 | 5-20 | Various Policy and LiveView tests | Multiple files | 1.5-2.4s each | Policy/LiveView |
 **Total Top 20:** ~44 seconds (12% of total time without `:slow`)
 **Note:** Many previously slow tests (UserLive.IndexTest, UserLive.ShowTest, Display/Formatting tests) are now tagged with `@tag :slow` and excluded from standard runs.
 ### Performance Hotspots Identified
 #### 1. Seeds Tests (~16.2s for 4 tests)
 **Status:** ✅ Optimized (reduced from 13 tests)  
 **Remaining Optimization Potential:** 3-5 seconds
 **Opportunities:**
 - Settings update could potentially be moved to `setup_all` (if sandbox allows)
 - Seeds execution could be further optimized (less data in test mode)
 - Idempotency test could be optimized (only 1x seeds instead of 2x)
 #### 2. User LiveView Tests (~35.5s for 10 tests)
 **Status:** ⏳ Identified for optimization  
 **Optimization Potential:** 15-20 seconds
 **Files:**
 - `test/mv_web/user_live/index_test.exs` (3 tests, ~10.2s)
 - `test/mv_web/user_live/form_test.exs` (4 tests, ~15.0s)
 - `test/mv_web/user_live/show_test.exs` (3 tests, ~10.3s)
 **Patterns:**
 - Many tests create user/member data
 - LiveView mounts are expensive
 - Form submissions with validations are slow
 **Recommended Actions:**
 - Move shared fixtures to `setup_all`
 - Reduce test data volume (3-5 users instead of 10+)
 - Optimize setup patterns for recurring patterns
 #### 3. Policy Tests (~8.7s for 3 tests)
 **Status:** ⏳ Identified for optimization  
 **Optimization Potential:** 5-8 seconds
 **Files:**
 - `test/mv/membership/member_policies_test.exs` (2 tests, ~6.1s)
 - `test/mv/accounts/user_policies_test.exs` (1 test, ~2.6s)
 **Pattern:**
 - Each test creates new roles/users/members
 - Roles are identical across tests
 **Recommended Actions:**
 - Create roles in `setup_all` (shared across tests)
 - Reuse common fixtures
 - Maintain test isolation while optimizing setup
 ---
 ## Future Optimization Opportunities
 ### Priority 1: User LiveView Tests Optimization
 **Estimated Savings:** 14-22 seconds  
 **Status:** 📋 Analysis Complete - Ready for Implementation
 #### Analysis Summary
 Analysis of User LiveView tests identified significant optimization opportunities:
 - **Framework functionality over-testing:** ~30 tests test Phoenix/Ash/Gettext core features
 - **Redundant test data creation:** Each test creates users/members independently
 - **Missing shared fixtures:** No `setup_all` usage for common data
 #### Current Performance
 **Top 20 Slowest Tests (User LiveView):**
 - `index_test.exs`: ~10.2s for 3 tests in Top 20
 - `form_test.exs`: ~15.0s for 4 tests in Top 20
 - `show_test.exs`: ~10.3s for 3 tests in Top 20
 - **Total:** ~35.5 seconds for User LiveView tests
 #### Optimization Opportunities
 **1. Remove Framework Functionality Tests (~30 tests, 8-12s saved)**
 - Remove translation tests (Gettext framework)
 - Remove navigation tests (Phoenix LiveView framework)
 - Remove validation tests (Ash framework)
 - Remove basic HTML rendering tests (consolidate into smoke test)
 - Remove password storage tests (AshAuthentication framework)
 **2. Implement Shared Fixtures (3-5s saved)**
 - Use `setup_all` for common test data in `index_test.exs` and `show_test.exs`
 - Share users for sorting/checkbox tests
 - Share common users/members across tests
 - **Note:** `form_test.exs` uses `async: false`, preventing `setup_all` usage
 **3. Consolidate Redundant Tests (~10 tests → 3-4 tests, 2-3s saved)**
 - Merge basic display tests into smoke test
 - Merge navigation tests into integration test
 - Reduce sorting tests to 1 integration test
 **4. Optimize Test Data Volume (1-2s saved)**
 - Use minimum required data (2 users for sorting, 2 for checkboxes)
 - Share data across tests via `setup_all`
 #### Tests to Keep (Business Logic)
 **Index Tests:**
 - `initially sorts by email ascending` - Tests default sort
 - `can sort email descending by clicking sort button` - Tests sort functionality
 - `select all automatically checks when all individual users are selected` - Business logic
 - `does not show system actor user in list` - Business rule
 - `displays linked member name in user list` - Business logic
 - Edge case tests
 **Form Tests:**
 - `creates user without password` - Business logic
 - `creates user with password when enabled` - Business logic
 - `admin sets new password for user` - Business logic
 - `selecting member and saving links member to user` - Business logic
 - Member linking/unlinking workflow tests
 **Show Tests:**
 - `displays password authentication status` - Business logic
 - `displays linked member when present` - Business logic
 - `redirects to user list when viewing system actor user` - Business rule
 #### Implementation Plan
 **Phase 1: Remove Framework Tests (1-2 hours, ⚠️ Very Low Risk)**
 - Remove translation, navigation, validation, and basic HTML rendering tests
 - Consolidate remaining display tests into smoke test
 **Phase 2: Implement Shared Fixtures (2-3 hours, ⚠️ Low Risk)**
 - Add `setup_all` to `index_test.exs` and `show_test.exs`
 - Update tests to use shared fixtures
 - Verify test isolation maintained
 **Phase 3: Consolidate Tests (1-2 hours, ⚠️ Very Low Risk)**
 - Merge basic display tests into smoke test
 - Merge navigation tests into integration test
 - Reduce sorting tests to 1 integration test
 **Risk Assessment:** ⚠️ **Low**
 - Framework functionality is tested by framework maintainers
 - Business logic tests remain intact
 - Shared fixtures maintain test isolation
 - Consolidation preserves coverage
 ### Priority 2: Policy Tests Optimization
 **Estimated Savings:** 5.5-9 seconds  
 **Status:** 📋 Analysis Complete - Ready for Decision
 #### Analysis Summary
 Analysis of policy tests identified significant optimization opportunities:
 - **Redundant fixture creation:** Roles and users created repeatedly across tests
 - **Framework functionality over-testing:** Many tests verify Ash policy framework behavior
 - **Test duplication:** Similar tests across different permission sets
 #### Current Performance
 **Policy Test Files Performance:**
 - `member_policies_test.exs`: 24 tests, ~66s (top 20)
 - `user_policies_test.exs`: 30 tests, ~66s (top 20)
 - `custom_field_value_policies_test.exs`: 20 tests, ~66s (top 20)
 - **Total:** 74 tests, ~152s total
 **Top 20 Slowest Policy Tests:** ~66 seconds
 #### Framework vs. Business Logic Analysis
 **Framework Functionality (Should NOT Test):**
 - Policy evaluation (how Ash evaluates policies)
 - Permission lookup (how Ash looks up permissions)
 - Scope filtering (how Ash applies scope filters)
 - Auto-filter behavior (how Ash auto-filters queries)
 - Forbidden vs NotFound (how Ash returns errors)
 **Business Logic (Should Test):**
 - Permission set definitions (what permissions each role has)
 - Scope definitions (what scopes each permission set uses)
 - Special cases (custom business rules)
 - Permission set behavior (how our permission sets differ)
 #### Optimization Opportunities
 **1. Remove Framework Functionality Tests (~22-34 tests, 3-4s saved)**
 - Remove "cannot" tests that verify error types (Forbidden, NotFound)
 - Remove tests that verify auto-filter behavior (framework)
 - Remove tests that verify permission evaluation (framework)
 - **Risk:** ⚠️ Very Low - Framework functionality is tested by Ash maintainers
 **2. Consolidate Redundant Tests (~6-8 tests → 2-3 tests, 1-2s saved)**
 - Merge similar tests across permission sets
 - Create integration tests that cover multiple permission sets
 - **Risk:** ⚠️ Low - Same coverage, fewer tests
 **3. Share Admin User Across Describe Blocks (1-2s saved)**
 - Create admin user once in module-level `setup`
 - Reuse admin user in helper functions
 - **Note:** `async: false` prevents `setup_all`, but module-level `setup` works
 - **Risk:** ⚠️ Low - Admin user is read-only in tests, safe to share
 **4. Reduce Test Data Volume (0.5-1s saved)**
 - Use minimum required data
 - Share fixtures where possible
 - **Risk:** ⚠️ Very Low - Still tests same functionality
 #### Test Classification Summary
 **Tests to Remove (Framework):**
 - `member_policies_test.exs`: ~10 tests (cannot create/destroy/update, auto-filter tests)
 - `user_policies_test.exs`: ~16 tests (cannot read/update/create/destroy, auto-filter tests)
 - `custom_field_value_policies_test.exs`: ~8 tests (similar "cannot" tests)
 **Tests to Consolidate (Redundant):**
 - `user_policies_test.exs`: 6 tests → 2 tests (can read/update own user record)
 **Tests to Keep (Business Logic):**
 - All "can" tests that verify permission set behavior
 - Special case tests (e.g., "user can always READ linked member")
 - AshAuthentication bypass tests (our integration)
 #### Implementation Plan
 **Phase 1: Remove Framework Tests (1-2 hours, ⚠️ Very Low Risk)**
 - Identify all "cannot" tests that verify error types
 - Remove tests that verify Ash auto-filter behavior
 - Remove tests that verify permission evaluation (framework)
 **Phase 2: Consolidate Redundant Tests (1-2 hours, ⚠️ Low Risk)**
 - Identify similar tests across permission sets
 - Create integration tests that cover multiple permission sets
 - Remove redundant individual tests
 **Phase 3: Share Admin User (1-2 hours, ⚠️ Low Risk)**
 - Add module-level `setup` to create admin user
 - Update helper functions to accept admin user parameter
 - Update all `setup` blocks to use shared admin user
 **Risk Assessment:** ⚠️ **Low**
 - Framework functionality is tested by Ash maintainers
 - Business logic tests remain intact
 - Admin user sharing maintains test isolation (read-only)
 - Consolidation preserves coverage
 ### Priority 3: Seeds Tests Further Optimization
 **Estimated Savings:** 3-5 seconds
 **Actions:**
 1. Investigate if settings update can be moved to `setup_all`
 2. Introduce seeds mode for tests (less data in test mode)
 3. Optimize idempotency test (only 1x seeds instead of 2x)
 **Risk Assessment:** ⚠️ **Low to Medium**
 - Sandbox limitations may prevent `setup_all` usage
 - Seeds mode would require careful implementation
 - Idempotency test optimization needs to maintain test validity
 ### Priority 4: Additional Test Isolation Improvements
 **Estimated Savings:** Variable (depends on specific tests)
 **Actions:**
 1. Review tests that load all records (similar to the critical test fix)
 2. Add query filters where appropriate
 3. Ensure proper test isolation in async tests
 **Risk Assessment:** ⚠️ **Very Low**
 - Similar to the critical test optimization (proven approach)
 - Improves test isolation and reliability

 ## Estimated Total Optimization Potential
 | Priority | Optimization | Estimated Savings |
 |----------|-------------|-------------------|
 | 1 | User LiveView Tests | 14-22s |
 | 2 | Policy Tests | 5.5-9s |
 | 3 | Seeds Tests Further | 3-5s |
 | 4 | Additional Isolation | Variable |
 | **Total Potential** | | **22.5-36 seconds** |
 **Projected Final Time:** From ~368 seconds (fast suite) to **~332-345 seconds** (~5.5-5.8 minutes) with remaining optimizations
 **Note:** Detailed analysis documents available:
 - User LiveView Tests: See "Priority 1: User LiveView Tests Optimization" section above
 - Policy Tests: See "Priority 2: Policy Tests Optimization" section above
 ---
 ## Risk Assessment Summary
 ### Overall Risk Level: ⚠️ **Low**
 All optimizations maintain test coverage while improving performance:
 | Optimization | Risk Level | Mitigation |
 |-------------|------------|------------|
 | Seeds tests reduction | ⚠️ Low | Coverage mapped to domain tests |
 | Performance tests tagging | ✅ Very Low | Tests still executed, just separately |
 | Critical test optimization | ✅ Very Low | Functionality unchanged, better isolation |
 | Future optimizations | ⚠️ Low | Careful implementation with verification |
 ### Monitoring Plan
 #### Success Criteria
 - ✅ Seeds tests execute in <20 seconds consistently
 - ✅ No increase in seeds-related deployment failures
 - ✅ No regression in authorization or membership fee bugs
 - ✅ Top 20 slowest tests: < 60 seconds (currently ~44s)
 - ✅ Total execution time (without `:slow`): < 10 minutes (currently 6.1 min)
 - ⏳ Slow tests execution time: < 2 minutes (currently ~1.3 min)
 #### What to Watch For
 1. **Production Seeds Failures:**
   - Monitor deployment logs for seeds errors
   - If failures increase, consider restoring detailed tests
 2. **Authorization Bugs After Seeds Changes:**
   - If role/permission bugs appear after seeds modifications
   - May indicate need for more seeds-specific role validation
 3. **Test Performance Regression:**
   - Monitor test execution times in CI
   - Alert if times increase significantly
 4. **Developer Feedback:**
   - If developers report missing test coverage
   - Adjust based on real-world experience

 ## Benchmarking and Analysis
 ### How to Benchmark Tests
 **ExUnit Built-in Benchmarking:**
 The test suite is configured to show the slowest tests automatically:
 ```elixir
 # test/test_helper.exs
 ExUnit.start(
  slowest: 10  # Shows 10 slowest tests at the end of test run
 )
 ```
 **Run Benchmark Analysis:**
 ```bash
 # Show slowest tests
 mix test --slowest 20
 # Exclude slow tests for faster feedback
 mix test --exclude slow --slowest 20
 # Run only slow tests
 mix test --only slow --slowest 10
 # Benchmark specific test file
 mix test test/mv_web/member_live/index_member_fields_display_test.exs --slowest 5
 ```
 ### Benchmarking Best Practices
 1. **Run benchmarks regularly** (e.g., monthly) to catch performance regressions
 2. **Compare isolated vs. full runs** to identify test isolation issues
 3. **Monitor CI execution times** to track trends over time
 4. **Document significant changes** in test performance

 ## Test Suite Structure
 ### Test Execution Modes
 **Fast Tests (Default):**
 - Excludes slow tests (`@tag :slow`)
 - Used for standard development workflow
 - Execution time: ~6 minutes
 - Command: `mix test --exclude slow` or `just test-fast`
 **Slow Tests:**
 - Tests tagged with `@tag :slow` or `@describetag :slow` (25 tests)
 - Low risk, >1 second execution time
 - UI/Display tests, workflow details, edge cases, performance tests
 - Execution time: ~1.3 minutes
 - Command: `mix test --only slow` or `just test-slow`
 - Excluded from standard CI runs
 **Full Test Suite (via Promotion):**
 - Triggered by promoting a build to `production` in Drone CI
 - Runs all tests (`mix test`) for comprehensive coverage
 - Execution time: ~7.4 minutes
 - Required before merging to `main` (enforced via branch protection)
 **All Tests:**
 - Includes both fast and slow tests
 - Used for comprehensive validation (pre-merge)
 - Execution time: ~7.4 minutes
 - Command: `mix test` or `just test`

 ## Best Practices for Test Performance
 ### When Writing New Tests
 1. **Use `async: true`** when possible (for parallel execution)
 2. **Filter queries** to only load necessary data
 3. **Share fixtures** in `setup_all` when appropriate
 4. **Tag performance tests** with `@tag :slow` if they use large datasets
 5. **Keep test data minimal** - only create what's needed for the test
 ### When Optimizing Existing Tests
 1. **Measure first** - Use `mix test --slowest` to identify bottlenecks
 2. **Compare isolated vs. full runs** - Identify test isolation issues
 3. **Optimize setup** - Move shared data to `setup_all` where possible
 4. **Filter queries** - Only load data needed for the test
 5. **Verify coverage** - Ensure optimizations don't reduce test coverage
 ### Test Tagging Guidelines
 #### Tag as `@tag :slow` when:
 1. **Performance Tests:**
   - Explicitly testing performance characteristics
   - Using large datasets (50+ records)
   - Testing scalability or query optimization
   - Validating N+1 query prevention
 2. **Low-Risk Tests (>1s):**
   - UI/Display/Formatting tests (not critical for every commit)
   - Workflow detail tests (not core functionality)
   - Edge cases with large datasets
   - Show page tests (core functionality covered by Index/Form tests)
   - Non-critical seeds tests (smoke tests, idempotency)
 #### Do NOT tag as `@tag :slow` when:
 - ❌ Test is slow due to inefficient setup (fix the setup instead)
 - ❌ Test is slow due to bugs (fix the bug instead)
 - ❌ Core CRUD operations (Member/User Create/Update/Destroy)
 - ❌ Basic Authentication/Authorization
 - ❌ Critical Bootstrap (Admin user, system roles)
 - ❌ Email Synchronization
 - ❌ Representative Policy tests (one per Permission Set + Action)
 - ❌ It's an integration test (use `@tag :integration` instead)

 ## Questions & Answers
 **Q: What if seeds create wrong data and break the system?**  
 A: The smoke test will fail if seeds raise errors. Domain tests ensure business logic is correct regardless of seeds content.
 **Q: What if we add a new critical bootstrap requirement?**  
 A: Add a new test to the "Critical bootstrap invariants" section in `test/seeds_test.exs`.
 **Q: How do we know the removed tests aren't needed?**  
 A: Monitor for 2-3 months. If no seeds-related bugs appear that would have been caught by removed tests, they were redundant.
 **Q: Should we restore the tests for important releases?**  
 A: Consider running the full test suite (including slow tests) before major releases. Daily development uses the optimized suite.
 **Q: How do I add a new performance test?**  
 A: Tag it with `@tag :slow` for individual tests or `@describetag :slow` for describe blocks. Use `@describetag` instead of `@moduletag` to avoid tagging unrelated tests. Include measurable performance assertions (query counts, timing with tolerance, etc.). See "Performance Test Guidelines" section above.
 **Q: Can I run slow tests locally?**  
 A: Yes, use `just test-slow` or `mix test --only slow`. They're excluded from standard runs for faster feedback.
 **Q: What is the "full test suite"?**  
 A: The full test suite runs **all tests** (`mix test`), including slow and UI tests. Tests tagged with `@tag :slow` or `@describetag :slow` are excluded from standard CI runs (`check-fast`) for faster feedback, but are included when promoting a build to `production` (`check-full`) before merging to `main`.
 **Q: Which tests should I tag as `:slow`?**  
 A: Tag tests with `@tag :slow` if they: (1) take >1 second, (2) have low risk (not critical for catching regressions), and (3) test UI/Display/Formatting or workflow details. See "Test Tagging Guidelines" section for details.
 **Q: What if a slow test fails in the full test suite?**  
 A: If a test in the full test suite fails, investigate the failure. If it indicates a critical regression, consider moving it back to the fast suite. If it's a flaky test, fix the test itself. The merge will be blocked until all tests pass.

  Minimal test suite for database seeds.
  This test suite focuses on critical deployment requirements:
  - Seeds run without errors (smoke test)
  - Seeds are idempotent (can be run multiple times)
  - Critical bootstrap invariants are met (Admin user, system roles)
  ## Removed Tests
  The following tests were removed to reduce test execution time.
  Their functionality is covered by domain-specific tests:
  - Member/fee type distribution tests → covered by `membership_fees/*_test.exs`
  - Cycle status variation tests → covered by `membership_fees/cycle_generator_test.exs`
  - Detailed role configuration tests → covered by `authorization/*_test.exs`
  - Permission set validation → covered by `authorization/permission_sets_test.exs`
  See `docs/test-optimization-seeds.md` for detailed rationale and coverage mapping.
