1. The default test case rules

1.1. Module name [test_login]: must start with test_ or end with _test 
1.2. Test class [Testlogin]: must start with Test, and cannot have an init method 
1.3. Test method [test_01_baili]: must start with test 
1.4. All The package package must have an __init__.py file

2. Execution order of test cases

unittest: Absolute execution order according to the size of the ASCII code

pytest: top to bottom by default

Change the default execution order of use cases: use mark mark

3. How to run the test case

For details on the meaning of running parameters, see: Analysis of Common Parameters Running in the Pytest Framework_Momo 18S Blog-CSDN Blog

3.1. Main function mode

if __name__ == '__main__':
    pytest.main(['-vs','-m smoke','test_01_baili'])

3.1.1. Main function mode: 4 operation modes

#1. Run all 
pytest.main() 
#2. Specify module [file] 
pytest.main(['-vs','test_login.py']) 
#3. Specify directory folder 
pytest.main(['-vs ','./interface_testcase']) 
#4. Specify the directory folder 2; specify the use case through nodeid to run: nodeid is composed of module name, separator, class name, method name, and function name Execution function: no class
    name 
pytest.main (['-vs', './interface_testcase/test_interface.py::test_01_func']) 
   execute method 
pytest.main(['-vs', './interface_testcase/test_interface.py::TestInterface::test_01'])

3.1.2. The file framework is as shown below

3.2. Command line mode

3.2.1. Command line mode: 4 operation modes

#1. Run all files: 
pytest 
#2. Execute the [smoke] use case of a certain file; expressions can also be used after -m, adding and, or, not keywords between tags 
pytest -vs test_login.py 
pytest -v -m smoke test_login.py 
#3. Specify the directory folder 
pytest -vs ./interface_testcase 
#4. Specify the directory folder 2; specify the use case through nodeid to run: nodeid consists of module name, separator, class name, method name, The function name constitutes 
   the execution function: no class name 
pytest -vs ./interface_testcase/test_interface.py::test_01_func 
   execution method 
pytest -vs ./interface_testcase/test_interface.py::TestInterface::test_01

3.2.2. Framework of the second operation mode

Remarks : The framework of the fourth operating mode is the same as that of the main function mode

3.3. Run by reading the configuration file pytest.ini

3.3.1.pytest.ini file considerations

pytest.ini is generally used in the implementation of enterprise automation testing, and is also the core configuration file of the pytest unit testing framework

Location: generally placed in the root directory of the project;
name: must be pytest.ini
Encoding format: must be ANSI, you can use notpad++ to modify the encoding format
Function: You can change the default test case rules of pytest
Running rules: Whether it is running in the mode of the main function or running in the command line mode, it will read the configuration file pytest.ini

3.3.2.pytest.ini file interpretation

Note: An error will be reported when executing with Chinese. After removing all Chinese, you can use notpad++ to modify the encoding format

3.3.3.pytest.ini file source code

[pytest]
addopts = -vs -m "smkoe"
testpaths = ./testcase/
python_files = test_*.py
python_classes = test*
python_functions = test

Remarks: Modify the naming rules of [pytest.ini file source code] module name, class name, and method name. The names of corresponding modules, classes, and methods also need to be modified according to the rules of pytest.ini
