3、 Five operation modes of unittest test cases

TestCase usage ：

import os
import unittest


class EcshopLogin(unittest.TestCase):

    # The test case 
    def test01_xiaoming(self):
        print(" Test Xiao Ming ")

    #  The test case 
    def test02_weiwei(self):
        print(" Test Pico ")

#  The test case 
    def test10_xiaohongi(self):
        print(" Test Xiaohong ")

if __name__ =='__main__':
    suite = unittest.TestSuite()
    testcase = unittest.defaultTestLoader.discover(start_dir=os.getcwd(),pattern='*.py')
    suite.addTests(testcase)
    unittest.main(defaultTest='suite')
    #unittest.TextTestRunner().run(suite) There is no difference between the results of the two calling methods 

1. Command line operation mode ：python -m unittest -v ecshop_login.EcshopLogin  -k *_weiwei   
python -m        Run a gate module in a script

python -v        --version It means more detailed output

ecshop_login.EcshopLogin        Module name . Class name . Method name

-k Matching mode ：

       1. wildcard ：-k *_weiwei

        2. character string ：-k weiwei

Suitable for integration jenkins When you use , All command line methods are called non GUI The way

postman: Not GUI,newman

jmeter:jmeter The order of

2. Use unittest.main Method , Run as a module

To configure pycharm Environment , Or use python Module name .py Way to run

if __name__ =='__main__':
    print('__________')
    unittest.main()

Read the results of execution ：

.         success

F        Failure        self.assertTrue(0)

E        error         raise Exception(” Custom exception ”)

S        skip         @unittest.skip(" This use case does not execute ")

Use case execution sequence ：

according to ASCLL Code rules ：【0-9 A-Z a-z】A=65, a=97

So the use case is named after 01-09, stay 10-99

The bottom principle of the frame ：

module='__main__',     The road strength of the test case  __main__ Represents the current module 
defaultTest=None,      Name of the case to be tested , The default is all 
 example ：defaultTest=["EcshopLogin.test01_xiaoming"]
argv=None,             Accept external parameters 
testRunner=None,       Test runner , Default TextTestRunner- Text format 
testLoader=loader.defaultTestLoader,      Specifies to use the default test case loader ,
exit=True,             Whether to end after the test is completed python Program 
verbosity=1,            similar -v  Yes 0,1,2,
failfast=None,          Whether to terminate the test in case of failure 
catchbreak=None,         Capture replication 
buffer=None,              Whether to capture the output stream 
warnings=None, *,          Whether to display a warning message 
tb_locals=False

What test suite does it use to run only part of the use cases ：

3. A single use case ：

if __name__ =='__main__':
    suite = unittest.TestSuite()
    suite.addTest(EcshopLogin("test01_xiaoming"))
    suite.addTest(EcshopLogin("test02_weiwei"))
    #unittest.main(defaultTest='suite') There is no difference between the results of the two calling methods 
    unittest.TextTestRunner().run(suite)

4. Use case set ：

if __name__ =='__main__':
    suite = unittest.TestSuite()
    testcase = [EcshopLogin("test01_xiaoming"),EcshopLogin("test10_xiaohongi")]
    suite.addTests(testcase) 
    unittest.main(defaultTest='suite')

5. File with .py End all use cases ：

#print(os.getcwd()) Get path

if __name__ =='__main__':
    suite = unittest.TestSuite()
    testcase =unittest.defaultTestLoader.discover(start_dir=os.getcwd(),pattern='*.py')
    suite.addTests(testcase)
    unittest.main(defaultTest='suite')
