test suite 、 The results are output to a file

Catalog

• 1、 test suite
  • 1.1、 Mode one ：unittest.main()
  • 1.2、 Mode two ：unittest.TestSuite()
  • 1.3、 Mode three ：unittest.defaultTestLoader()
• 2、 The results are output to a file

1、 test suite

1.1、 Mode one ：unittest.main()

1、 establish test_Case1.py file

Script code ：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#  Import unittest modular 
import unittest
"""
 test suite ： Mode one ：unittest.main()
"""
#  Define test classes , The parent class is unittest.TestCase
class TestDemo(unittest.TestCase):

    #  Each test method is executed before running 
    def setUp(self):
        print('setUp')

    #  Execute after each test method is run 
    def tearDown(self):
        print('tearDown')

    #  All test methods should be based on test Start with 
    def test_case1(self):
        print('test_case1')

    def test_case3(self):
        print('test_case3')

    def test_case2(self):
        print('test_case2')

if __name__ == '__main__':
    unittest.main(verbosity=2)

Copy

2、 perform test_Case1.py file , Running results ：

unittest.main() Method will search all under this module test The initial test method , And automatically execute them .

The execution order is the naming order ： Execute first test_case1, Re execution test_case2, Finally, execute test_case3.

1.2、 Mode two ：unittest.TestSuite()

1、 establish test_Case2.py file

Script code ：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#  Import unittest modular 
import unittest
"""
 test suite ： Mode two ：unittest.TestSuite()
"""
#  Define test classes , The parent class is unittest.TestCase
class TestDemo(unittest.TestCase):

    #  Each test method is executed before running 
    def setUp(self):
        print('setUp')

    #  Execute after each test method is run 
    def tearDown(self):
        print('tearDown')

    #  All test methods should be based on test Start with 
    def test_case1(self):
        print('test_case1')

    def test_case2(self):
        print('test_case2')

    def test_case3(self):
        print('test_case3')

if __name__ == '__main__':
    suite = unittest.TestSuite()
    suite.addTest(TestDemo('test_case2'))
    suite.addTest(TestDemo('test_case1'))
    runner = unittest.TextTestRunner(verbosity=2)
    runner.run(suite)

Copy

2、 perform test_Case2.py file , Running results ：

（1） Construct test set , Instantiate the test suite .

suite = unittest.TestSuite()

Copy

（2） Load test cases into the test suite .

The execution sequence is installation loading sequence ： Execute first test_case2, Re execution test_case1, Don't execute test_case3（ Because it is not loaded ）.

suite.addTest(TestDemo('test_case2'))
suite.addTest(TestDemo('test_case1'))

Copy

（3） Execute test case , Instantiation TextTestRunner class .

runner = unittest.TextTestRunner(verbosity=2)

Copy

（4） Use run() Method to run the test suite （ That is, run all the use cases in the test suite ）.

runner.run(suite)

Copy

1.3、 Mode three ：unittest.defaultTestLoader()

1、 establish test_Case3.py file

Script code ：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#  Import unittest modular 
import unittest
"""
 test suite ： Mode three ：unittest.defaultTestLoader()
"""
#  Define test classes , The parent class is unittest.TestCase
class TestDemo(unittest.TestCase):

    #  Each test method is executed before running 
    def setUp(self):
        print('setUp')

    #  Execute after each test method is run 
    def tearDown(self):
        print('tearDown')

    #  All test methods should be based on test Start with 
    def test_case1(self):
        print('test_case1')

    def test_case3(self):
        print('test_case3')

    def test_case2(self):
        print('test_case2')

if __name__ == '__main__':
    test_dir = './'
    discover = unittest.defaultTestLoader.discover(test_dir, pattern='test_*3.py')
    runner = unittest.TextTestRunner(verbosity=2)
    runner.run(discover)

Copy

2、 perform test_Case3.py file , Running results ：

（1） Construct test set , Use defaultTestLoader Of discover Method to find the test case file .

The execution order is the naming order ： Execute first test_case1, Re execution test_case2, Finally, execute test_case3.

test_dir = './'
discover = unittest.defaultTestLoader.discover(test_dir, pattern='test_*3.py')

Copy

（2） Execute test case , Instantiation TextTestRunner class .

runner = unittest.TextTestRunner(verbosity=2)

Copy

（3） Use run() Method to run the test suite （ That is, run all the use cases in the test suite ）.

runner.run(discover)

Copy

2、 The results are output to a file

When executing a test case , Want to output the results to a file , You can use Python Of open() Function to operate on a file .

1、 establish OutputFile.py file

Script code ：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#  Import unittest modular 
import unittest
"""
 The results are output to a file 
"""
#  Define test classes , The parent class is unittest.TestCase
class TestDemo(unittest.TestCase):

    #  Each test method is executed before running 
    def setUp(self):
        print('setUp')

    #  Execute after each test method is run 
    def tearDown(self):
        print('tearDown')

    #  All test methods should be based on test Start with 
    def test_case1(self):
        print('test_case1')

    def test_case2(self):
        print('test_case2')

if __name__ == '__main__':
    suite = unittest.TestSuite()
    suite.addTest(TestDemo('test_case1'))
    suite.addTest(TestDemo('test_case2'))
    #  Perform the test , Output the result to OutputFile In file 
    with open('OutputFile.txt', 'a') as f:
        runner = unittest.TextTestRunner(stream=f, verbosity=2)
        runner.run(suite)

Copy

2、 perform OutputFile.py file , Running results ：

At the same time, it will generate OutputFile.txt file （ If the file exists, it does not need to be generated again ）, As shown in the figure ： Output the results to this file .
