First to tell you about the selenium environment, you can in the CMD first look at their own selenium version:Enter it and you can install it.I would like to tell you how to skip the verification code to log in, the results of a lot of friends and I asked my environment configuration problems, so I think it is detailed with you to explain, I also make a record. You can take a look ahead of the issue of skip

1.Webdriver principleWebdirver is a Web automation tool that provides a unified Webdriver interface to the browser, which is submitted by client, our test script, and the remote server browser responds to the request. Compared to the original selenium1 in the Selenium RC is more convenient, the browser operation more flexible.2. Positioning(1) Positioning of elements:The positioning of the elements can be a

positioning of the page, and the method encapsulated by the business operation code associated with those elements.4. Code reuse, which reduces the amount of test script code.5. Clear hierarchy, while supporting the development of multiple writing automation scripts, such as how many pages each person writes, does not affect others.6. It is recommended that both the page class and the business logic approach give a meaningful name to make it easy for
