nti.nose_traceback_info 1.0.2

nose_traceback_info

Have you ever wanted supplemental (debugging) info included in an error or failure traceback produced by nose? Do you find that nose’s Failure Detail plugin fails you (for example, because you use PyHamcrest matchers)? Developing server software using Zope, Plone, Paste or WebError? Then this plugin might be the solution you’re looking for: it allows you to add whatever detailed information you want to any frame in your traceback. Turn a traceback like this:

Traceback (most recent call last):
File "/.../nti.nose_traceback_info/src/nti/nose_traceback_info/tests/test_nose_traceback_info.py", line 39, in test_format_failure
  t, formatted, _ = self.plugin.formatFailure(None, exc_info)
File "/.../nti.nose_traceback_info/src/nti/nose_traceback_info/__init__.py", line 48, in formatFailure
  return self.formatError( test, exc_info)
File "/.../nti.nose_traceback_info/src/nti/nose_traceback_info/__init__.py", line 31, in formatError
  t, v, tb = exc_info
TypeError: 'builtin_function_or_method' object is not iterable

into a traceback like this:

TypeError: Traceback (most recent call last):
Module unittest.case, line 331, in run
  testMethod()
Module nti.nose_traceback_info.tests.test_nose_traceback_info, line 39, in test_format_failure
  t, formatted, _ = self.plugin.formatFailure(None, exc_info)
  - __traceback_info__: ("calling plugin with test and exc_info", None, <build-in function exc_info>)
Module nti.nose_traceback_info, line 48, in formatFailure
  return self.formatError( test, exc_info)
Module nti.nose_traceback_info, line 31, in formatError
  t, v, tb = exc_info
  - __traceback_info__: ("Test and exc_info args", None, <built-in function exc_info>)
TypeError: 'builtin_function_or_method' object is not iterable

def formatError(self, test, exc_info):
    __traceback_info__ = "Test and exc_info args", test, exc_info
    t, v, tb = exc_info
