Applying marks to classes

You can apply the @pytest.mark decorator to a class. This will apply that same mark to all tests methods in that class, avoiding have to copy and paste the mark code over all test methods:

@pytest.mark.timeout(10)class TestCore:    def test_simple_simulation(self):        ...    def test_compute_tracers(self):        ...

The previous code is essentially the same as the following code:

class TestCore:    @pytest.mark.timeout(10)    def test_simple_simulation(self):        ...    @pytest.mark.timeout(10)    def test_compute_tracers(self):        ...

However, there is one difference: applying the @pytest.mark decorator to a class means that all its subclasses will inherit the mark. Subclassing test classes is not common, but it is sometimes a useful technique to ...
