Tracing Fixture Execution with –setup-show
Now that we have two tests using the same fixture, it would be interesting to know exactly in what order everything is getting called.
Fortunately, pytest provides the command-line flag, --setup-show, which shows us the order of operations of tests and fixtures, including the setup and teardown phases of the fixtures:
| | $ cd /path/to/code/ch3 |
| | $ pytest --setup-show test_count.py |
| | ======================== test session starts ========================= |
| | collected 2 items |
| | |
| | test_count.py |
| | SETUP F cards_db |
| | ch3/test_count.py::test_empty (fixtures used: cards_db). |
| | TEARDOWN F cards_db |
| | SETUP F cards_db |
| | ch3/test_count.py::test_two (fixtures used: cards_db). |
