Introduction to unittest framework and the first demo

1、 effect ： Manage test cases 、 Assertion 、 Generate test reports

2、Unittest Official document ： Look at grammar and usage , You can also see online tutorials

unittest — Unit testing framework — Python 3.10.5 documentation

3、 Part of the

test fixture： Test fixed components  

test case： The test case , The smallest unit of test execution

test suite： test suite , It is a use case set , It is used to summarize the test cases that should be executed together

test runner： Test runner , It is the component that designs the test execution mode , It provides a way to display the output results , You can use icons 、 Text 、html Way to show the test results

 TestFixture Fusion runs in code , Embodied in TestCase in

4、unittest stay python3 in , yes python Built in module of , It can be used without installation

example ：

 5、 Modify the operation mode

1） The above figure is the default unittest Way of execution

The default operation mode can be selected as follows ：

 

 2） Normal mode execution

choice edit configuration

 

Select the content of the plus sign. Just look at the previous figure

 apply After that , Look at the execution mode in the upper right corner of the page and change it to normal mode

The above figure is executing 2 There are two points below , Prove the execution is successful  

 E Represents execution error , The script is wrong, and the program is wrong

F Delegate execution failed

 6、unittest Runtime , Points needing attention

Unittest Running test cases , It has to be inherited TestCase Method , And this method defaults to test start , The default execution order is test The following characters follow ASCII Code size execution

#  Guide pack 
import unittest

#  Create inheritance unittest.TestCase Class 

class FirstDemo(unittest.TestCase):

    # Create test cases 
    def test01(self):
        print(" perform 1")

    def test02(self):
        print(" perform 2")


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