Use switchTo() window

Use switch window to switch to the window you want, then perform the test on that window.

Windows and Tabs are used interchangeably.

Example from above site of using an iterator to switch window:

driver.findElement(By.id(“id of the link which opens new window”)).click();\ 
waitForNumberofWindowsToEqual(2);//this method is for wait
Set handles = driver.getWindowHandles();
firstWinHandle = driver.getWindowHandle(); handles.remove(firstWinHandle);
String winHandle=handles.iterator().next(); 
if (winHandle!=firstWinHandle){
secondWinHandle=winHandle; //Storing handle of second window handle
driver.switchTo().window(secondWinHandle);
