I have test that click on link and then new browser window open and in new browser window I need to check some elements are present. How to switch to new Browser window that was opened using BEHAT/MINK?
You can use switchToWindow($windowName)
method.
$this->getSession()->switchToWindow($windowName);
Method declaration is here
You can get all windows from current session and then switch to the second one for example
$windowNames = $this->getSession()->getWindowNames();
if(count($windowNames) > 1) {
$this->getSession()->switchToWindow($windowNames[1]);
}
