在Selenium Webdriver中从一个选项卡导航到另一个选项卡后，按钮的xpath不起作用，如何使它起作用？

Question

// opening the base URL

driver1.get(baseUrl+"/");

// opening a new tab

driver1.findElement(By.cssSelector("Body")).sendKeys(Keys.COMMAND + "t");

driver1.get("my URL"); 

// getting back to the first tab             

driver1.findElement(By.cssSelector("body")).sendKeys(Keys.COMMAND, Keys.SHIFT, "{");

// I want to signup by clicking the sign up button

driver1.findElement(By.xpath("/html/body/div[1]/header/div[2]/button")).click();

The error that I get after running is : "Error communicating with the remote browser. It may have died."

But when I run the same code without the navigation, the button click works fine, then it means there is no problem with the xpath.

Answer 1

The information which browser you are using would be very interesting. And the webdriver doesn't need to control the visbile Tab. So i wouldn't let the Browser change the Tab and I would use the "switchTo" Method of the webdriver.
More information to this topic is here .

Answer 2

As @Kikkirej mentuined, i see no reason to use sendKeys to switch between opened tabs. Use Selenium instead, it is a much better approach.

Edit: in addition, try to provide more information, especially the most basic part - the browser you are automating.
