You can put fixtures into individual test files, but to share fixtures among multiple test files, you need to use a conftest.py file somewhere centrally located for all of the tests. For the Tasks project, all of the fixtures will be in tasks_proj/tests/conftest.py. From there, the fixtures can be shared by any test.
