Python unittest: Генерировать несколько тестов программно? [дубликат]

С проверкой носа, тогда да. См. Это: https://nose.readthedocs.org/en/latest/writing_tests.html#test-generators

нос (предложено @Paul Hankin )

#!/usr/bin/env python
# file: test_pairs_nose.py
from nose.tools import eq_ as eq

from mymodule import f

def test_pairs(): 
    for input, output in [ (2, 332), (234, 99213), (9, 3), ]:
        yield _test_f, input, output

def _test_f(input, output):
    try:
        eq(f(input), output)
    except AssertionError:
        if input == 9: # expected failure
            from nose.exc import SkipTest
            raise SkipTest("expected failure")
        else:
            raise

if __name__=="__main__":
   import nose; nose.main()

Пример:

$ nosetests test_pairs_nose -v
test_pairs_nose.test_pairs(2, 332) ... ok
test_pairs_nose.test_pairs(234, 99213) ... ok
test_pairs_nose.test_pairs(9, 3) ... SKIP: expected failure

----------------------------------------------------------------------
Ran 3 tests in 0.001s

OK (SKIP=1)

unittest (подход аналогичен @ doublep's one )

#!/usr/bin/env python
import unittest2 as unittest
from mymodule import f

def add_tests(generator):
    def class_decorator(cls):
        """Add tests to `cls` generated by `generator()`."""
        for f, input, output in generator():
            test = lambda self, i=input, o=output, f=f: f(self, i, o)
            test.__name__ = "test_%s(%r, %r)" % (f.__name__, input, output)
            setattr(cls, test.__name__, test)
        return cls
    return class_decorator

def _test_pairs():
    def t(self, input, output):
        self.assertEqual(f(input), output)

    for input, output in [ (2, 332), (234, 99213), (9, 3), ]:
        tt = t if input != 9 else unittest.expectedFailure(t)
        yield tt, input, output

class TestCase(unittest.TestCase):
    pass
TestCase = add_tests(_test_pairs)(TestCase)

if __name__=="__main__":
    unittest.main()

Пример:

$ python test_pairs_unit2.py -v
test_t(2, 332) (__main__.TestCase) ... ok
test_t(234, 99213) (__main__.TestCase) ... ok
test_t(9, 3) (__main__.TestCase) ... expected failure

----------------------------------------------------------------------
Ran 3 tests in 0.000s

OK (expected failures=1)

Если вы этого не сделаете хотите установить unittest2 , затем добавьте:

try:    
    import unittest2 as unittest
except ImportError:
    import unittest
    if not hasattr(unittest, 'expectedFailure'):
       import functools
       def _expectedFailure(func):
           @functools.wraps(func)
           def wrapper(*args, **kwargs):
               try:
                   func(*args, **kwargs)
               except AssertionError:
                   pass
               else:
                   raise AssertionError("UnexpectedSuccess")
           return wrapper
       unittest.expectedFailure = _expectedFailure
