python+selenium+unitest用例失败重运行

Posted 2020-09-26

经过多次研读和调试unittest代码，后来发现一个也可以重运行setUp()和dearDown()的解决办法，那就是修改源码，我们重新建一个模块套件类来覆盖原来的TestSuite类

实例代码：

[python] view plain copy

1. class Suit(unittest.TestSuite):  
2.     def run(self, result, debug=False):  
3.         failcount = 1#失败总运行次数  
4.         class_num = 1  
5.         topLevel = False  
6.         if getattr(result, ‘_testRunEntered‘, False) is False:  
7.             result._testRunEntered = topLevel = True  
8.   
9.         for test in self:  
10.             case_num = 1  
11.             if result.shouldStop:  
12.                 break  
13.               
14.             success_flag = True  
15.             while success_flag:    
16.                 if _isnotsuite(test):  
17.                     self._tearDownPreviousClass(test, result)  
18.                     self._handleModuleFixture(test, result)  
19.                     self._handleClassSetUp(test, result)  
20.                     result._previousTestClass = test.__class__  
21.                     if (getattr(test.__class__, ‘_classSetupFailed‘, False) or  
22.                         getattr(result, ‘_moduleSetUpFailed‘, False)):  
23.                         if class_num > failcount:  
24.                             success_flag = False  
25.                         else:  
26.                             time.sleep(5)  
27.                             result._previousTestClass = None  
28.                             print ‘类%s第%s次重新初始化执行‘%(test.__class__,class_num)  
29.                             class_num += 1  
30.                         continue  
31.   
32.                 if not debug:  
33.                     test(result)  
34.                 else:  
35.                     test.debug()  
36.                   
37.                 if result.result[-1][0]==1 or result.result[-1][0]==2:#结果为fail和err用例判断  
38.                     if case_num > failcount:  
39.                         success_flag = False  
40.                     else:    
41.                         print ‘用例%s第%s次重新执行‘%(test,case_num)  
42.                         case_num += 1  
43.                 else:  
44.                     success_flag = False  
45.                       
46.         if topLevel:  
47.             self._tearDownPreviousClass(None, result)  
48.             self._handleModuleTearDown(result)  
49.             result._testRunEntered = False  
50.         return result  

然后测试使用

alltests=suit.Suit()

alltests.addtest(WidgetTestCase("testDefaultSize"))

runner =HTMLTestRunner.HTMLTestRunner(stream=fp,verbosity=2,title=‘Android测试报告‘,description=‘用例执行情况:‘,)
runner.run(alltests)

运行完后，有失败重运行的用例都会打印在测试报告里，方便查阅
