Is it possible to add specific tests to the collected tests?

You can also use x-unit style for setups and teardowns:

class TestSetupTeardownExample:

    @classmethod
    def setup_class(cls):
        print("setup class")

    @classmethod
    def teardown_class(cls):
        print("teardown class")

    def setup_method(self, method):
        print("setup method")

    def teardown_method(self, method):
        print("teardown method")

    def test_setup_teardown_example(self):
        assert 1 == 1

When I run this test, the following will be printed:

setup class
teardown class
setup method
teardown method

You can see that when you run it with -s option: $ pytest -s.

I think the methods are pretty self-explanatory, but it really does this:

• setup_class: runs once before all test cases
• teardown_class: runs once after all test cases
• setup_method: runs before every test case in the class
• teardown_method: runs after every test case in the class

I think fixtures are a bit more powerful, but this is perhaps a bit more readable and understandable than decorators which might not be easy to understand when you see it for the first time.

You want to consider using fixtures

@pytest.fixture
def f1():
    pass # your steps should be here

# you can also use fixtures to do steps after test:
@pytest.fixture
def f2():
    pass # your "before test" steps should be here
    yield
    pass # your "after test" steps should be here
