Protractor will not switchTo().window(handle). nameOrHandle Undefined error.

Protractor will not switchTo().window(handle). nameOrHandle Undefined error.

I usually just look through the webdriver code when trying to find documentation. Check out https://code.google.com/p/selenium/source/browse/javascript/webdriver/webdriver.js and search for 'switchTo'.

I think your problem is that popUpHandle is not defined until after ptor.getAllWindowHandlers(), so when you run ptor.switchTo().window(popUpHandle) it's not yet defined. I can't quite tell though - could you post the entire test?

[rlrhett]

I am not sure I understand what you are saying. ptor.getAllWindowHandlers() is run in the BeforeEach setup. In fact, I have it in a runs/waitFor block to make sure that it has finished and the promise has been fulfilled before running the test. As far as I can tell ptor.switchTo().window(popUpHandle) is being run after ptor.getAllWindowsHandlers() has returned. Every test I run before the switchTo() including expect(popUpHandle).toBeDefined() passes.

Regardless, that is the entire test. Here it is as one block of text if that helps:

var Pby, parentHandle, popUpHandle, ptor, util;

util = require('util');

Pby = protractor.By;

parentHandle = {};

popUpHandle = {};

beforeEach(function() {
  var handlesDone;
  ptor = protractor.getInstance();
  handlesDone = false;
  ptor.get('#/');
  runs(function() {
    return ptor.findElement(Pby.className('btn')).click();
  });
  waits(3000);
  runs(function() {
    return ptor.getAllWindowHandles().then(function(handles) {
      popUpHandle = handles[1];
      parentHandle = handles[0];
      handlesDone = true;
    });
  });
  waitsFor(function() {
    return handlesDone;
  });
});

describe('login', function() {
  return it('should switch to popUp\'s handle', function() {
    var handle;
    expect(popUpHandle).toBeDefined();
    handle = driver.switchTo().window(popUpHandle).getWindowHandle();
    expect(handle).toEqual(popUpHandle);
  });
});

Any further thoughts? Is this a bug? Is anyone else having this issue? Does this problem occur with straight webDriverJS? Is there more I can add to shed light on this problem? I am completely stalled on e2e testing unless I can figure out how to log into the app, so I am open to any suggestions.

Thanks.

This is indeed an issue with the control flow. In protractor, expect is patched so that it understands webdriver promises, and waits for them to resolve before executing. That's why your expect(popUpHandle).toBeDefined(); is passing, but popUpHandle is still empty later.

You should be able to fix by rearranging your test like this:

var Pby ptor, util;

util = require('util');

Pby = protractor.By;

var handlePromise;

beforeEach(function() {
  ptor = protractor.getInstance();
  ptor.get('#/');
  ptor.findElement(Pby.className('btn')).click();
  handlePromise = ptor.getAllWindowHandles();
});

describe('login', function() {
  return it('should switch to popUp\'s handle', function() {
    handlePromise.then(function(handles) {
      var popUpHandle = handles[1];
      var handle = driver.switchTo().window(popUpHandle).getWindowHandle();
      expect(handle).toEqual(popUpHandle);
    });
});

[rlrhett]

That solved the undefined error. I still don't understand why the waitsFor didn't do the job, but at least I can move on with setting up tests. Thanks!

Just as information for other possible users, I modified a bit the promise handle:

            var handles = handlePromise.then(function (handles) {
                popUpHandle = handles[1];
                var handle = browser.switchTo().window(popUpHandle);
                handle = browser.getWindowHandle();
                expect(handle).toEqual(popUpHandle);
                browser.driver.executeScript('window.focus();');
            });

And it worked beautifully. After this point I could send the data to the inputs in the window and do whatever I wanted with it. Pretty.

Hi @DanielaValero , I tried the way you provided here, I got an error. Could you please check it? I posted it here: http://stackoverflow.com/questions/25873294/how-to-switch-to-a-new-pop-up-windowa-non-angular-app-to-run-protractor
Thank you.

Hi @juliemr and @DanielaValero , me also facing the same issue reported by @jasonnjit . can u please provide me the solution

Thanks in ADVANCE!!!!

Hello,

I am not currently active with this issue. Can't help right now. Sorry

[prakashomp]

HI,

Iam also having same problem with angularJS page .
The size of handles are showing only.
how to enter text in popup text field.

[balakmr08]

HI guys ,

My pop up is also angular based , so my friends asked me to use some what like this:

element(by.id("").element(by.model("<model_name>")).sendKeys("value");

and its working for me.

[jasonnjit]

@balakmr08 Is that working for a pop-up? Cause I found switchTo() only works for a new window or a new tab, but not a new pop-up.

[balakmr08]

@jasonnjit : yes , its working for popup . U need to use any specific attribute to get into the popup (like id , name or css of the popup) and using this we can access inner elements

Hi everyone,
I can still reproduce this with 3.0.0 and webdriver 2.53.0. Code:

it('checks tabs', () => {
  const url1 = 'http://stackoverflow.com/';
  const url2 = 'http://programmers.stackexchange.com/';

  let windowHandles = {
    oldTab: '',
    newTab: ''
  };

  await browser.get(url1);
  await browser.getWindowHandle().then(handle => {
     windowHandles.oldTab = handle;
  });

  await browser.executeScript('window.open("' + url2 + '", "whatever")');

  await browser.getAllWindowHandles()
    .then(handles => {
      expect(handles[0]).toEqual(windowHandles.oldTab);

      windowHandles.newTab = handles[1];
      return browser.driver.switchTo().window(windowHandles.oldTab);
    })
    .then(() => {
      let handle = browser.driver.getWindowHandle();
      expect(handle).toEqual(windowHandles.oldTab);
    })
    .then(() => browser.sleep(6000));
});

Hello, I have the same issue. I am using :

1. Selenium WebDriver dll. Version 2.53.0 Installed by Nuget
2. IEDriverServer.exe Version 2.53.0 64 bit version downloaded from Selenium Website

My code is same as @latobibor 's code, and it gets stuck on line
browser.driver.switchTo().window(windowHandles.oldTab);

Is it a Selenium Bug, or is this the wrong syntax to Switch Window Handle?

when i debug the issue, i get the following exception after waiting a long time :

An exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll but was not handled in user code

Additional information: The HTTP request to the remote WebDriver server for URL http://127.0.0.1:4444/wd/hub/session/36fa4074-3b34-4dea-9da8-c8278b135c4f/window timed out after 240 seconds.

For a single pop-up I just do browser.switchTo().frame(1); and works like a champ.
