Python unittest Understanding

First, the operation process

Second, how to use:

1, define an inheritance unittest. TestCase class in which the Test_ beginning method is the test case at the time of execution

############################name:test_unittest.py#!/usr/bin/env python#_*_ coding:utf-8 _*_defAdd (A, b):returnA +bdefMinus (A, b):returnA-bdefmulti (A, B):returnA *bdefDivide (A, b):returnA/b

###########################name:test_case.py#!/usr/bin/env python#_*_ coding:utf-8 _*_Importtest_unittestImportUnitTestclassMyTest (unittest. TestCase):defTest_add (self): self.assertequal (5,test_unittest.add (2,3))    defTest_minus (self): self.assertequal (2,test_unittest.minus (5,3))    defTest_multil (self): self.assertequal (6,test_unittest.multi (2,3))    deftest_divide (self): self.assertequal (2,test_unittest.divide (6,2))if __name__=='__main__': Unittest.main (verbosity=2)

2, the above direct execution, you can add multiple test methods to a testsuile (test suite), execute a test suite

Testloader (). Loadtestsfromnames (['Test_case. MyTest','Test_case. MyTest2'])) Runner= UnitTest. Texttestrunner (verbosity=2) Runner.run (suite)

3. Output the result to a file

4. SetUp () and teardown ()

5. Skip a Use case

6. Using Htmltestrunner
