One . explain ： This project adopts the idea of process control , Not quoted unittest&pytest Unit testing framework, etc .
Two . Project introduction
1. Purpose ： Test an official website login function module can be used normally .
2. Use cases
2.1. Enter the correct user name and password , Verify successful login
2.2. Enter a user name in the correct format and an incorrect password , Failed to verify login , And the message is correct
2.3. Enter a properly formatted user name and any password , Failed to verify login , And the message is correct
2.4. Both username and password are empty , Failed to verify login , And the message is correct
2.5. One of the user name and password is empty , Failed to verify login , And the message is correct
3. Environmental Science
Windows10 +Python3.6+selenium3.13+Pycharm
3.1. Environment most people will build , Find Baidu if you have anything , Search a basket , ha-ha ！ When I first learned, I also had various problems , Fortunately, it has been solved , Thank you for your strong existence ！ There is no need to write about how to build the environment , Go straight to the point .
3、 ... and . Script design
1. Purpose
The test script should achieve ： Script portability , Script modularization , Test data separation , Output test report, etc
2. Script design pattern 
3. Code implementation
3.1. Project directory structure 
3.2. notes ： The following files are stored in the same directory
