通过鼻子测试运行跳过的测试（不跳过不起作用）

Question

I have a lot of legacy test like this. Tests are skipped with unittest but are run with nosetests.

import unittest
import nose
import time


class BaseTestClass(unittest.TestCase):

    @unittest.skip("Skipped")
    def test_add(self):
        """Test 1"""
        print "Execute test 1"
        time.sleep(5)

    def test_sub(self):
        """Test 2"""
        print "Execute test 2"
        time.sleep(5)

if __name__ == '__main__':
    nose.run(argv=["nose", ".", "--verbosity=2", "--nocapture", '--no-skip'])

I want to run all skipped tests. Looks like "no-skip" - option not works, become I have output

Execute test 2
Test 1 ... Test 2 ... ok

----------------------------------------------------------------------
Ran 2 tests in 5.001s

OK

looks like test is present in output but doesn't execute code inside.

I expected to see:

Test 1 ... ok
Execute test 1
Test 2 ... ok
Execute test 2
----------------------------------------------------------------------
Ran 2 tests in 10 s

OK

Answer 1

I got a similar problem, and after some research the issue seems to be that --no-skip does not have anything to do with unittests.skip but with the handling the exception nose.SkipTest .

I ended up with a hacky solution that does the job in my case. Maybe it can help somebody. It consists of using your own custom skip function so that it "piggybacks" the --no-skip flag and reacts accordingly.

import sys
import unittest

no_skip_mode = '--no-skip' in sys.argv

def skip(reason):
    if no_skip_mode:
        # Don't decorate the test function. Just return as is.
        def dummy_wrapper(fn):
            return fn

        return dummy_wrapper

    return unittest.skip(reason)

I guess you could try to monkeypatch unittest.skip .
