Selenium_webdriver can't drive browser.

Recently, when many students are learning selenium tools, one of the most common problems is why I can't open the browser when I create a browser instance, driver.get (url), or why I can't enter the corresponding URL even if I open it.

Recently, when I was self-learning selenium tools, I also encountered these problems, and finally found that it was the driver version, because webdriver needs to call the corresponding driver when enabling our specified browser Chrome/Firefox/I e, and different browser versions correspond to different drivers. Some drivers only support which browser-related versions, for example, Chrome:

-ChromeDriver v2.7 (2013-11-22)-Supports Chrome v30-33Resolved issue 615: ChromeDriver doesn't work well with auto detect proxy settings [OS-Windows, Pri-0] Resolved issue 614: Implement new redirectionless / session command [Pri-0] Resolved issue 625: logging broken on windows [Pri-0] Resolved issue 573: chromedriver crashes on windows occasionally [OS-Windows Pri-1]-ChromeDriver v2.6 (2013-11-04)-Supports Chrome v29-32Resolved issue 599: Chromedriver failes after MacOS X Mavericks upgrade [OS-Mac, Pri-0, Type-Defect] Resolved issue 585: Return user data dir via capabilities []-ChromeDriver v2.5 (2013-11-01)-Supports Chrome v29-32Resolved issue 600: Support minidump for chrome crashes on Linux with a new capability minidump_path.

As we can see above, the browser versions supported by different ChromeDriver are different. If we use the driver of ChromeDriver v2.4 to drive Chrome 35 or above, there may be various problems mentioned above. Other types of browsers are similar. These problems are usually caused by drivers.

Download the ChromeDriver driver and the supported browser version number, which can be found at the following link:
