If the second parameter of assert is used normally it prints it out debug information.E.g. with the following code:
class TestTest: def test_test(self): assert 1 == 2, "TEST"
The following debug information is printed:
tests\test_test.py:1 (TestTest.test_test)1 != 2Expected :2Actual :1<Click to see difference>self = <tests.test_test.TestTest object at 0x000002147E5B1B08> def test_test(self):> assert 1 == 2, "TEST"E AssertionError: TESTE assert 1 == 2E +1E -2test_test.py:3: AssertionError
However, if the assert happens in a helper function, this is not printed:
class TestTest: def test_test(self): self.verify(1) def verify(self, parameter): assert 1 == 2, "TEST"
results in:
tests\test_test.py:1 (TestTest.test_test)1 != 2Expected :2Actual :1<Click to see difference>self = <tests.test_test.TestTest object at 0x000002AFDF1D5AC8> def test_test(self):> self.verify(1)test_test.py:3:
So the stack trace is incomplete and the debug information not shown.
UPDATE:This only happens when starting the test through PyCharm (2021.3).
Is there any way to fix this?
