Failure of Errorclasses
-----------------------
Errorclasses (skips, deprecations, etc.) define whether or not they
represent test failures.
>>> import os
>>> import sys
>>> from nose.plugins.plugintest import run_buffered as run
>>> from nose.plugins.skip import Skip
>>> from nose.plugins.deprecated import Deprecated
>>> support = os.path.join(os.path.dirname(__file__), 'support')
>>> sys.path.insert(0, support)
>>> from errorclass_failure_plugin import Todo, TodoPlugin, \
... NonFailureTodoPlugin
>>> todo_test = os.path.join(support, 'errorclass_failing_test.py')
>>> misc_test = os.path.join(support, 'errorclass_tests.py')
nose.plugins.errorclass.ErrorClass has an argument ``isfailure``. With a
true isfailure, when the errorclass' exception is raised by a test,
tracebacks are printed.
>>> run(argv=["nosetests", "-v", "--with-todo", todo_test],
... plugins=[TodoPlugin()]) # doctest: +REPORT_NDIFF
errorclass_failing_test.test_todo ... TODO: fix me
errorclass_failing_test.test_2 ... ok
<BLANKLINE>
======================================================================
TODO: errorclass_failing_test.test_todo
----------------------------------------------------------------------
Traceback (most recent call last):
...
Todo: fix me
<BLANKLINE>
----------------------------------------------------------------------
Ran 2 tests in ...s
<BLANKLINE>
FAILED (TODO=1)
Also, ``--stop`` stops the test run.
>>> run(argv=["nosetests", "-v", "--with-todo", "--stop", todo_test],
... plugins=[TodoPlugin()]) # doctest: +REPORT_NDIFF
errorclass_failing_test.test_todo ... TODO: fix me
<BLANKLINE>

----------------------------------------------------------------------
Traceback (most recent call last):
...
Todo: fix me
<BLANKLINE>
----------------------------------------------------------------------
Ran 1 test in ...s
<BLANKLINE>
FAILED (TODO=1)
With a false .isfailure, errorclass exceptions raised by tests are
treated as "ignored errors." For ignored errors, tracebacks are not
printed, and the test run does not stop.
>>> run(argv=["nosetests", "-v", "--with-non-failure-todo", "--stop",
... todo_test],
... plugins=[NonFailureTodoPlugin()]) # doctest: +REPORT_NDIFF
errorclass_failing_test.test_todo ... TODO: fix me
errorclass_failing_test.test_2 ... ok
<BLANKLINE>
----------------------------------------------------------------------
Ran 2 tests in ...s
<BLANKLINE>
OK (TODO=1)
Exception detail strings of errorclass errors are always printed when
-v is in effect, regardless of whether the error is ignored. Note
that exception detail strings may have more than one line.
>>> run(argv=["nosetests", "-v", "--with-todo", misc_test],
... plugins=[TodoPlugin(), Skip(), Deprecated()])
... # doctest: +REPORT_NDIFF
errorclass_tests.test_todo ... TODO: fix me
errorclass_tests.test_2 ... ok
errorclass_tests.test_3 ... SKIP: skipety-skip
errorclass_tests.test_4 ... SKIP
errorclass_tests.test_5 ... DEPRECATED: spam

Without -v, the exception detail strings are only displayed if the
error is not ignored (otherwise, there's no traceback).
>>> run(argv=["nosetests", "--with-todo", misc_test],
... plugins=[TodoPlugin(), Skip(), Deprecated()])
... # doctest: +REPORT_NDIFF
