Selenium Lesson 14 – Handling Windows Dialogs

Lesson 13 - Handling Windows Dialogs

In this lesson we look at how we are going to address the selenium’s common limitations and how to achieve it using other tools.

According to me Selenium is one of the best open source, free tool for testing web applications. It’s quite powerful and gives you the facility to write down your test case in your favorite language ( from the plenty of languages it supports ). But it sucks when it comes to handle the dialogs. Dialog boxes are like ghosts to selenium, It can’t even see them.
That’s because dialogs are native to the operating system you are running and selenium are designed to identify only web component.

After searching too much on the Internet and other forums, I finally got the solution to all my problems. The solution is too simple. As you can’t handle the dialog box through selenium, use the other software to do this. And AutoIT is best at this.

AutoIt
Autoit is a free scripting language designed to automate the windows component. It’s just like an extensive VB Script and it allows you to convert the script in executable (exe). So what you can do is, write down the script to handle dialog box using AutoIt, convert it into executable and then call the executable when required. So let’s see guys how to do it. But before we begin you need to download and install the Autoit. Download it from the following link

Handing Modal Dialogs
Modal Dialog box mean once it has appeared all the focus of that application will be on that dialog box only. You will not able to access any of the other component of parent window until you close the dialog box.

Some of the modal dialog boxes that we face frequently during web application testing are

Save Dialog Box
Save dialog box is bit different in IE and in Firefox. So I have write down two separate script for that.

AutoIt script to handle Firefox Save Dialog box
In Firefox when you click on the button/link to download a file. First it will ask you for you permission once you select yes, If you have selected to ask you for the path then only a dialog box will display.

If you will click on download link following dialogbox will appear in Firfox.
Save Dialog box in Firefox

If you click “Save File” on above dialogbox this dialog box will apppears, Yeah if you have choose to ask where to save file from Option.
If you click save on above dialogbox this will appear.
The executable and the script below will handle both of these dialogboxes. You just need to call it in proper way. Your need to pass arguments while calling the script or executable as following.
Save_Dialog_FF Operation FilePath
Operaion: Operation you want to perform when dialog box appears. Can be any of the following
cancel: Press Cancel on the dialog box
Save: Press the Save as Dialog box
FilePath: It’s an option argument. It’s a full path where you want to save the file.
i.e. C:\myfile.txt

; set the select mode to select using substring
AutoItSetOption("WinTitleMatchMode","2")
 
if $CmdLine[0] < 2 then
 ; Arguments are not enough
 msgbox(0,"Error","Supply all the Arguments, Dialog title,Save/Cancel and Path to save(optional)")
 Exit
EndIf

; wait until dialog box appears
WinWait($CmdLine[1]) ; match the window with substring
$title = WinGetTitle($CmdLine[1]) ; retrives whole window title
WinActive($title);

; if user choose to save file
If (StringCompare($CmdLine[2],"Save",0) = 0) Then

 WinActivate($title)
 WinWaitActive($title)
 Sleep(1)

 ; If firefox is set the save the file on some specific location without asking user.
 ;Save the File
 send("{TAB}")
 Send("{ENTER}")
 if ( StringCompare(WinGetTitle("[active]"),$title,0) = 0 ) Then
  WinActivate($title)
  send("{TAB}")
  Send("{ENTER}")
 EndIf

 ;if firefox is set to prompt user for save path.
 if WinExists("Enter name") Then
  $title = WinGetTitle("Enter name")
  if($CmdLine[0] = 2) Then
  ; If user hasn't provided path to save
  ;save to default path.
  WinActivate($title)
  ControlClick($title,"","Button2")

  Else
  ; If user has provided path 
  ;Set path and save file
  WinActivate($title)
  WinWaitActive($title)
  ControlSetText($title,"","Edit1",$CmdLine[3])
  ControlClick($title,"","Button2")
  EndIf

 Else
  ;Firefox is configured to save file at specific location
  Exit
 EndIf

EndIf
; do not save the file
If (StringCompare($CmdLine[2],"Cancel",0) = 0) Then
 WinWaitActive($title)
 Send("{ESCAPE}")
EndIf

AutoIt script to handle Internet Explorer Save Dialog box
Unlike Firefox dialog box internet explorers dialog box is bit different. First dialog box prompts with three choices Run, Save and cancel. The second dialog box is same as Firefox. If you click on the downloadlink in the internet explorer following dialog box will display.Selenium-Handle Save Dialog box of Internet ExplorereIf you will click on “Save” button on the above dialog box Following dialog box will appear which will ask for the path to save the file.Selenium-Handle Save Dialog box of Internet ExplorereThe executable and the script below will handle both of these dialog boxes.

If (StringCompare($CmdLine[2],"Save",0) = 0) Then

WinWaitActive($title)
ControlClick($title,"","Button2")
; Wait for the new dialogbox to open
Sleep(2)
WinWait("Save")
$title = WinGetTitle("Save")
;$title = WinGetTitle("[active]")
if($CmdLine[0] = 2) Then
;click on the save button
WinWaitActive($title)

EndIf

EndIf

If (StringCompare($CmdLine[2],"Cancel",0) = 0) Then
WinWaitActive($title)
ControlClick($title,"","Button3")
EndIf

Download above script

Now you just need to copy and paste above scripts in Autoit IDE, convert those into executables, Save those to the project folder. And then just make a call to the executables with proper arguments, just before you execute the step which invokes the dialog box as shows here.


import org.testng.annotations.*;
import com.thoughtworks.selenium.DefaultSelenium;
import com.thoughtworks.selenium.Selenium;

public class Handle_Dialogs {
private Selenium selenium;

 @BeforeClass
 public void startSelenium() {
  selenium = new DefaultSelenium("localhost", 4444, "*chrome", "http://www.autoitscript.com/");
  selenium.start();
 }
 
 @AfterClass(alwaysRun=true)
 public void stopSelenium() {
  this.selenium.stop();
 }
 
 
 @Test
 public void handleSaveDialog() throws Exception {
  String[] dialog;
  
  selenium.open("/site/autoit/downloads/");
  selenium.waitForPageToLoad("3000");
  selenium.click("//img[@alt='Download AutoIt']");
    
  Thread.sleep(2000);
  String browser = selenium.getEval("navigator.userAgent");
  if(browser.contains("IE")){
   System.out.print("Browser= IE "+browser);
   dialog =  new String[]{ "Save_Dialog_IE.exe","Download","Save" };
   Runtime.getRuntime().exec(dialog);
  }
  if(browser.contains("Firefox")){
   System.out.print("Browser= Firefox "+browser);
   dialog = new String[] { "Save_Dialog_FF.exe","Opening","save" };
   Runtime.getRuntime().exec(dialog);
  }
 }

}

Download above File

User Name and Password Dialog Box.

following is the AutoIt script to handle to User name and password dialog box.

AutoItSetOption("WinTitleMatchMode","2")

if $CmdLine[0] < 3 then
msgbox(0,"Error","Supply all the Arguments, Dialog title User Name, Password")
Exit
EndIf

WinWait($CmdLine[1]) ; match the window with substring
$title = WinGetTitle($CmdLine[1]) ; retrives whole window title
ControlSend($title,"","Edit2",$CmdLine[2]);Sets User Name
ControlSend($title,"","Edit3",$CmdLine[3]);Sets Password
ControlClick($title,"","OK");
