TestCase

Bases: OrigTestCase

Enhanced test case, provides extra functionality (e.g. an assertErrorRegex method).

assertEqual(a, b, msg=None)

Make assertEqual always print useful messages

assertErrorRegex(error, regex, call, *args, **kwargs)

Convenience method to match regex with the expected error message. Example: self.assertErrorRegex(OSError, "No such file or directory", os.remove, '/no/such/file')

assertExists(path, msg=None)

Assert the given path exists

assertNotExists(path, msg=None)

Assert the given path exists

convert_exception_to_str(err)

Convert an Exception instance to a string.

get_stderr()

Return output captured from stderr until now.

get_stdout()

Return output captured from stdout until now.

is_string(x)

test if the variable x is a string)

mock_stderr(enable)

Enable/disable mocking stdout.

mock_stdout(enable)

Enable/disable mocking stdout.

mocked_stdout_stderr(mock_stdout=True, mock_stderr=True)

Context manager to mock stdout and stderr

setUp()

Prepare test case.

tearDown()

Cleanup after running a test.

nicediff(txta, txtb, offset=5)

generate unified diff style output ndiff has nice indicators what is different, but prints the whole content each line that is interesting starts with non-space unified diff only prints changes and some offset around it

return list with diff (one per line) (not a generator like ndiff or unified_diff)
