A, selenium2.0 brief
General browser testing framework (crawler frame) different, Selenium2.0 actually consists of two parts Selenium + webdriver, Selenium responsible for interpreting the user's instruction (code), webdriver is responsible for the control and browser page parsing. So when using Selenium2.0 requires a corresponding version of webdriver and browser, the program is running will start a real browser by webdriver. Due to the combination webdriver + browser, Selenium does not exist for js, ajax resolve problems, which directly use the browser to the site code parsing and obtaining the results of web code, so Selenium is the best web automated testing framework, but also the perfect js / ajax page crawlers.

Chromedriver.exe downloaded into the root directory of C to
Fourth, the test project
