Run Browsers in Parallel

We need to be able to run two browsers in parallel up to a certain point and take a screenshot to test functionality of two users in the same space as how our application would react when  that situa...

    Hi,

     

    If the browser is at different pages during the test, than it should be no problem to distinguish these two pages just by web address.

    If the address is the same, then:

    -- Page is a logical object provided by TestComplete to support cross-browser testing. Every Page object has complimentary BrowserWindow object that represents actual parent object (container) for the Page one. Because BrowserWindow object represents a window object provided by OS, it has its handle;

    -- It is possible to match Page object to its BrowserWindow container using this code (provided by SmartBear;s Support somewhere in time, VBScript)

CTRL-N opens a new tab to a page... however, if the page does not have a different URL than the original page, then TestComplete can't make the distinction.

Does it have to be Chrome?  You could, potentially, open up the second page in a different browser and do the check from there.

And the second window is opening to the browser home page, where as the original window is in the application at the time that the Cntrl-N keypress is sent. The second window, if you spy it, even shows as BrowserWindow(1), but all action in it happen in the first window. And even though the second window shows as BrowserWindow(1), the other attributes are the same as the first window 

Selenium accomplishes this through handles. Can TC do it this way, too?

    Shifting from one browser window to the other shifts the index... what used to be 0 is now 1 and vice versa.  BrowserWindow is for operating with the browser application itself.  If you need to operate with the application in the web page, you need to work with the page objects on the browser process.  

    Say your application is at url http://myapp.com/ and the home page is about:blank, then you should see in your object browser the Sys.Browser("chrome") with two page objects... one for page("http://myapp.com/") and one for page("about:blank").  Interacting with the application means you interact with the page object for your application.

     

    If you open a second page to your application, you know have two page objects with the same URL.  You could work, probably with the ID property to distinguish them but, each time you close a browser tab and re-open it, the ID will change.  So, this is something you'll have to work around.  What you will need to do is send commands and stuff to those different pages.  In code, you'll need to distinguish the two by noting the ID of the two pages in code (rather than depending upon static mapping) and operating on them that way.  

     

    I don't know if this is "handles" necessarily, but it's how TestComplete identifies pages... they are objects off the browser containing the Web application under test.

      The way I've always done it (and this is through code) is that you get an array of all running chrome processes and get the window handles before opening the new window. Open window, get handles, and compare to the list taken before opening the window. Odd handle out is the new window. Rinse, repeat for the second window. You can then switch between the two windows using their handles and the switchTo(<handle>) function that comes with WebDriver
