When an AssertionError is thrown during the fixture set up, then _count_relevant_tb_levels will return 1. Then, the traceback of the error will not be reported.
To reproduce:
Here I have two tests with wrong fixtures. One raises a ZeroDivisionError and the other one an AssertionError
import fixtures
import testtools
class WrongFixtureWithoutTrace(fixtures.Fixture):
def setUp(self):
super(WrongFixtureWithoutTrace, self).setUp()
raise AssertionError('error')
class WrongFixtureWithTrace(fixtures.Fixture):
def setUp(self):
super(WrongFixtureWithTrace, self).setUp()
1/0
class TestCase(testtools.TestCase):
def test_without_trace(self):
self.useFixture(WrongFixtureWithoutTrace())
def test_with_trace(self):
self.useFixture(WrongFixtureWithTrace())
When I run them, I get:
======================================================================
ERROR: test_with_trace (test.TestCase)

Ran 2 tests in 5.854s
FAILED (failures=1, errors=1)
Not on the second test that there is only one line of the trace, hiding where and why the error occured. |
