PyUnit - BioHackersNet

UnitTest의 Python용 모듈. 버젼 2.1부터 built-in에 포함됨.

http://pyunit.sourceforge.net/

JUnit을 모델로 만들었기때문에 매우 유사.

테스팅 방법들

assertEquals(a, b, "message when not equal") = assertEqual = failUnlessEqual
assertNotEquals(a, b, "message when equal") = assertNotEqual = failIfEqual
assert_(boolean, "message when false") = failUnless
failIf(2 > 1)
fail("message") 무조건 실패
failUnlessRaises(exceptionClass, callableObj, *args, **kwargs) = assertRaises
failUnlessEqual

원하는 테스트만을 실행하고 싶다면,

   1 def testAll():
   2     unittest.main(argv=('','-v'))
   3 
   4 def testPart():
   5     myTests = [TestClass('testMethod'),
   6               ]
   7     suite = unittest.TestSuite()
   8     for eachTest in myTests:
   9         suite.addTest(eachTest)
  10     unittest.TextTestRunner().run(suite)
  11 
  12 if __name__=='__main__':
  13     #testAll()
  14     testPart()
