Navigating to a fresh window using Selenium/Protractor in Javascript

Seeking assistance with accessing a new "pop-up" window that appears after clicking a "login" button.

The code I am currently using to capture the window handle seems to be ineffective even though I am able to reach the displayed window. My scenario involves using protractor within my pages, but the new non-angular based window requires me to switch to using Selenium WebDriver while in that window. (Is there a potential issue with this approach?)

Below is the snippet of code used to create the selenium driver and an attempt to switch to the new pop-up window's handle. I keep encountering "No Such Element" errors when trying to locate a form on the page.

// Create selenium webdriver / driver
var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

// Ensure the new window pops up and we navigate to it correctly
var handlePromise = browser.driver.getAllWindowHandles();
handlePromise.then(function (handles) {
    var popUpHandle = handles[1];

    // Change to the new handle
    browser.driver.switchTo().window(popUpHandle);

    var popUpHandleFinal = browser.driver.getWindowHandle();
    expect(popUpHandleFinal).toEqual(popUpHandle);
});

A few points to address:

  1. If I remove "browser" from "browser.driver.switchTo().window(popUpHandle)" and use just "driver.switchTo().window(popUpHandle)", I encounter an error stating "UnknownError: unknown error: 'name' must be a nonempty string." This is because the "switchTo()" method on driver cannot be null. The error resolves when using the original code.

  2. I'm unsure if I should be utilizing protractor (global "browser" variable) or defaulting to "driver" (Selenium) for managing windows.

Appreciate any guidance you can provide.

Answer №1

With the most recent update of Protractor (v2.2), there should be no issue with using window handles to manage multiple windows. As mentioned by P.T, it is unnecessary to create a separate driver instance as the global variable browser will suffice. The parent window has an index of 0, while any pop-up windows will have subsequent indices. Here is an example of how to switch to a pop-up window:

browser.getAllWindowHandles().then(function(handles){
    browser.switchTo().window(handles[1]).then(function(){
        // Perform actions on the pop-up window
    });
});

I hope this explanation is helpful.

Answer №2

If you're ever faced with the challenge of opening a pop-up window by clicking a link or button, remember to insert a pause after the click event using browser.sleep(ms).

I found that this simple addition helped me resolve the issue of encountering an error message stating "missing 'handle' parameter".

element(by.className("name")).click();
browser.sleep(10000); //Remember to include this line
var windowHandles = browser.getAllWindowHandles();
windowHandles.then(function(handles) 
{
    var parentWindow = handles[0];
    var popupWindow = handles[1];
    browser.switchTo().window(popupWindow);
    browser.switchTo().window(parentWindow);
})

Answer №3

When trying to access a website using https:// and then being redirected to http://, a security popup may appear due to the potential security risks involved.

1 - To resolve this issue, make sure both applications are configured to use either https:// or http://.

Answer №4

Ensure the window is accessible because the count begins at 0 for the window. Therefore, attempt decreasing the count and utilizing it, there is a possibility that it will function.. ;) This approach proved successful in my case..
