New submission from Naitree Zhu <[email protected]>:
When using @skip decorator, `reason` argument is required. But one could easily
overlook that and use it like so:
class SomeTest(TestCase):
@skip
def test_method(self):
# ...
The test actually passes when running with unittest, because it's equivalent to
class SomeTest(TestCase):
def test_method(self):
# ...
test_method = skip(test_method)
This gives the illusion that @skip decorator worked as expected.
I propose we should check the passed in `reason`, and raise error if it looks
like a function/method, therefore prevent this erroneous usage.
In practice, this behavior has misled people using the decorator in the
unintended way. For example: In this chapter of Test-Driven Development with
Python
(http://www.obeythetestinggoat.com/book/chapter_organising_test_files.html),
the author used @skip decorator without `reason` argument.
