text Selenium UI测试

Posted 2021-05-02

1. create class library .net core project

2. install packages:
xunit, xunit.runner.visualstudio, selenium.webdriver, selenium.webdriver.ChromeDriver
Microsoft.extensions.PlatformAbstractions, DotNetSeleniumExtras.PageObjects.Core

3. Go to Debug > start without debuging

4. Unit test
