About the Selenium webdriver browser tab, the current market on the latest browser, when clicked on a link to open a new page is in the browser to open a tab, and selenium can only switch to the window method, can only operate, not intuitive to see the page. Later I thought of selenium interface actions can simulate keyboard operation, and click on the keyboard "Ctrl+tab" key combination can switch the browser's tab, as long as the following code is placed on the tab to operate before the page, if there are more than one tab, more than a few executions.

The code is as follows:

Import Org.openqa.selenium.Keys; 
Import org.openqa.selenium.interactions.Actions;


Actions action = new actions (driver);
