Dynamically create or add a test to each test suite?

If I have test, which I would like perform automatically after each test suite/file. In Python unittest I can do something like this:

# base.py file
class Base(unittest.TestCase):

    def test_999(self):
        assert check_crash()
        
# my_test.py file
class TestClass(Base):
    
    def test_01(self):
        assert do_something()
        
    def test_02(self):
        assert other_thing()

And when writing new test suite, only thing to remember, is that one needs to inherit Base and test_999 is automatically executed.

But is there way to same thing pytest? So that this:

def test_01():
    assert do_something()

def test_02():
    assert other_thing()

Would look like this during execution time and in some automatic way?

def test_01():
    assert do_something()

def test_02():
    assert other_thing()

def test_999():
    assert check_crash()

I know that I can workaround the problem by writing plugin and doing this checkup after the all test have been executed. But then it would not be a test, it would be some post action that would fail and it would not be clear what and why it did fail (example xunit output would show that all test did pass.)

Closing this as an inactive question - hopefully fixtures are working for you 🙂

Exactly. That’s what makes pytest’s fixture system so incredibly powerful.

Let me know if you hit any snags or have any questions about how they work, or if you hit any problems with how to structure them, and I’ll be more than happy to help out.
