venkatesan_G02 has asked for the wisdom of the Perl Monks concerning the following question:

Hi All,

I am currently working with WWW::Selenium module and i am stuck up with the following problem.

My requirement is i need to search whether a particular window is open or not before performing any action.

I have given below a sample code i have been working with


#!C:/Perl/bin/perl.exe

use WWW::Selenium;

my $sel = WWW::Selenium->new( host => "localhost", 
                                    port => 5555, 
                                    browser => "*firefox", 
                                    browser_url => "http://www.google.
+com" );
$sel->start;

$sel->open("/");

$sel->select_window("CPAN - Google Search");

$sel->pause("3000");

$sel->type("q", "www::selenium");

$sel->key_press("q","\\13");

$sel->pause("300");

$sel->stop;

[download]

This code searches if a window with title "CPAN - Google search" is open or not. If open, it will search for www::selenium in that google window. The window is open but still i am receiving Error: Could not find window with title CPAN - Google Search

Could someone help me out with this requirement?

Thanks

    If I read the documentation for WWW::Selenium correctly, $sel->select_window() needs additional help to determine the appropriate window:

    <quote> 

    $sel->select_window($window_id)

    Selects a popup window using a window locator; once a popup window
+ has been selected, all commands go to that window. To select the mai
+n window again, use null as the target. Window locators provide diffe
+rent ways of specifying the window object:by title, by internal JavaS
+cript "name," or by JavaScript variable.

        * title=My Special Window:Finds the window using the text that
+ appears in the title bar. Be careful;two windows can share the same 
+title. If that happens, this locator willjust pick one.
        * name=myWindow:Finds the window using its internal JavaScript
+ "name" property. This is the second parameter "windowName" passed to
+ the JavaScript method window.open(url, windowName, windowFeatures, r
+eplaceFlag)(which Selenium intercepts).
        * var=variableName:Some pop-up windows are unnamed (anonymous)
+, but are associated with a JavaScript variable name in the current a
+pplication window, e.g. "window.foo = window.open(url);". In those ca
+ses, you can open the window using"var=foo".

    If no window locator prefix is provided, we'll try to guess what y
+ou mean like this:

    1.) if windowID is null, (or the string "null") then it is assumed
+ the user is referring to the original window instantiated by the bro
+wser).

    2.) if the value of the "windowID" parameter is a JavaScript varia
+ble name in the current application window, then it is assumed that t
+his variable contains the return value from a call to the JavaScript 
+window.open() method.

    3.) Otherwise, selenium looks in a hash it maintains that maps str
+ing names to window "names".

    4.) If that fails, we'll try looping over all of the known windows
+ to try to find the appropriate "title".Since "title" is not necessar
+ily unique, this may have unexpected behavior.

    If you're having trouble figuring out the name of a window that yo
+u want to manipulate, look at the Selenium log messages which identif
+y the names of windows created via window.open (and therefore interce
+pted by Selenium).  You will see messages like the following for each
+ window as it is opened:

debug: window.open call intercepted; window ID (which you can use with
+ selectWindow()) is "myNewWindow"

    </quote>

    I suspect that you are falling into items 3 and 4, and the name of the window isn't really "CPAN - Google Search". (In my browser, the window is titled "CPAN - Google Search - Mozilla Firefox".)

    Update -- Cleaned up the syntax in the first sentence.

      Hi,

      Is there a way to find the ID of the open window. Please note that the window is not opened by window.open command.

        venkatesan_G02,
        Have you read Using WWW::Selenium To Test Or Automate An Ajax Website? In there, I showed an example of how to find a window not opened with window.open. It might not be immediately useful but if you combine it with some of the other Selenium methods (get_all_window_ids or get_all_window_titles), you should be able to figure it out.

        Cheers - L~R
