1, Run 
    1, right click 
    2, in operation Terminal (console): 
       first adding 
       IF __name__ __ ==' __ main__ ': 
            unittest.main () 
    Terminal (console) enter the command: python <module name .py> 
    
2, the test suite (the TestSuite) 
    command (all) execution: python <module name .py> -m unittest 
    single execution: python -m unittest <module name class name.> 
             Python -m unittest <module name. class name. method name> 
    
    
3, loading (TestLoader) 
    need to initialize an object, suite test suite (a collection of) 
    3.1 - a first method) 
        # initialization test suite 
        Suite unittest.TestSuite = () 
            
        # to test kit which added test, first import module 
        cases = [class name ( "method name"), the class name ( 'method name')] 
        suite.addTests (Cases) 
        
    . 3.2-- second method) 
        Suite = unittest.TestSuite (= Cases Tests)
    
    
4, run, test report file, 
    
first open a file 
    with Open ( 'TXT', 'w', encoding = 'utf8') AS f: 
    # initialize runner, logging detail level, slightly -> fine (0, 1 (default ), 2) 
    Runner = unittest.TextTestRunner (F, the verbosity = 0) 
    # run 
    runner.run (Suite) 
    
. 5, the execution order with the unittest embodiment is a method name, in particular according to the ASCII code 
   , if according to the ASCII code, can add value 
    def test_add_1_success (Self): 
        Pass 
    DEF test_add_2_success (Self): 
        Pass 
        
. 6, the setUp attention to the case and the tearDown # 
    DEF the setUp (Self): 
    # preconditions 
    automatically executed inside the program setup before the test method # 
    def TearDown (self): 
    after # postcondition 
    automatically executed inside the program after Teardown test method # 


7, TestLoader used to load test 
# loading module can also be tested in accordance with class loading, own rules to automatically load; 
    7.1) initialization loader
    = unittest.TestLoader Loader () 
    # test class according to load test 
    cases = loader.loadTestFromTestCase (class name) 
    Suite1 = unittest.TestSuite () 
    suite1.addTests (Cases) 

. 8, the test case automatic discovery (Discover) 
    # = the unittest Suite .TestSuite () 
    # initialization Loader 
    Loader unittest.Testloader = () 
    # automatic discovery test 
    start_dir = os.path.dirname (os.path.abspath with (__ file__)) 
    Suite1 = loader.discover (start_dir) 

9.HTMLtestrunner 
    9.1 introduced HTMLtestrunner 
        from HTMLTestRunnerNew import HTMLTestrunner 
        modified portion 
        with Open ( 'dem.html', 'WB') AS F: 
        # initialization Runner, logging level of detail, slightly -> fine (0,1 (default), 2)
        runner = unittest.TextTestRunner (f, verbosity = 2, title = ' test report name', tester = 'name testers') 
        # Run 
        runner.run (Suite) 
        
    9.2 Test Report report into a folder 
        dynamically generating a time file name 
        
        Mr. into a report folder 
        report_dir = os.path.join (start_dir, 'report') 
        IF not os.path.exists (report_dir): 
            os.mkdir (report_dir) 
        
        # reporting format report / 2019-09-19. html 
        introduced datatime 
        from datatime import datatime 
        time_str = datatime.now () the strftime. ( '% Y-M-% D%% H:% M:% S') 
        file_name = the os.path.join (report_dir, time_str + 'html')
