Type: Code Smell Detection
Test frameworks provide a mechanism to skip tests if their prerequisites are not met, by either calling dedicated methods (e.g: unittest.TestCase.skipTest, pytest.skip, ...) or using decorators (e.g: unittest.skip, pytest.mark.skip, ...)
Using a return statement instead will make the test succeed, even though no assertion has been performed. It is therefore better to flag the test as skipped in such situation.
This rule raises an issue when a return is performed conditionally at the beginning of a test method.
No issue will be raised if the return is unconditional as S1763 already raises an issue in such case.
The supported frameworks are Pytest and Unittest.
