+This file can be used to define fixtures thate are then used by other tests which
+depend on [demo]. For this to work
+
+1. the Runner class of the other test needs to define the depencency as seen
+   by referencing RunnerDemo in the dependencies list:
+
+from src.tests_demo.runner_demo import RunnerDemo
+
+class RunnerOther(Runner):
+    dependencies = [RunnerDemo]
+
+
+2. the specific tests that rely on these fixtures need to import the fixtures.
+   To globally import for all tests in 'other', the import should be done in conftest:
+
+in 'conftest.py' in 'test_other' dir:
+from src.tests_demo.fixtures_demo import demo_fixture
