AutoIt Tutorial – AutoIt Download, Install & Basic AutoIt Script

This is an AutoIt Tutorial for Beginners. Learn to Download, Install and Write Basic AutoIt Scripts to Handle Windows Pop-up using AutoIt and Selenium:

Pop-ups are those irritating windows that come up while we work on something important and interrupt our concentration. It is necessary to get rid of them while testing.

In this article, we shall discuss how to handle window pop-ups in automation testing using AutoIt.

This tutorial covers:

  • How to handle window pop-ups in Selenium WebDriver,
  • Uploading or downloading the files or images by transferring our control from Selenium WebDriver to AutoIt
  • How to call the AutoIt script from our program

But first, let’s understand what is AutoIt, how to install and use it.

AutoIt Tutorial

What is AutoIt?

AutoIt V3 is a freeware tool which is used for automating anything in Windows environment. AutoIt script is written in a BASIC language. It can simulate any combination of keystrokes, mouse movement and window/control manipulation.

Through AutoIt, we can prepare scripts for our routine actions like file input/output operations, application handling, resources monitoring, and administrative tasks and so on. However, in this article, we shall limit our discussion to handling window pop-ups in Selenium WebDriver.

While doing automation through Selenium or through any other tool for that matter, we all encounter a common problem, windows pop-ups. As Selenium is confined to automating browsers, desktop window is out of scope. Web applications sometimes need to interact with the desktops to perform things like file downloads and uploads. There are tools available for automating these sorts of workflow such as AutoIt, Robot Framework, Silk Test etc.

We can upload or download the files or images by transferring our control from Selenium WebDriver to AutoIt. We need to explicitly call the AutoIt script from our program.

How to write AutoIt script:

  • Identify the Windows control, through AutoItV3 Windows Info tool for 64 bit or 32 bit depending on your operating system
  • Click on Finder Tool and mouse hover over the object for which you want the properties
  • It will capture the properties of pop-up like Title, Class, Position, Size, Style, Handle and so on

  • Then with the help of above-captured properties, write a script in SciTE script editor or in notepad and save the script with .au3 extension
  • Now compile the .au3 script using AutoIt Script to EXE converter, which converts .au3 file to .exe file
  • In that editor provide source and destination folder location and click on convert button, it will create a .exe file

  • Else right click you’re saved .au3 script, it will show compile options. Select compile to 64bit or compile to32 bit option and will create a .exe file in the same folder.
  • Wherever you encounter download/ upload pop-up window in your Selenium test case, execute the .exe file
  • Syntax to call .exe file in your script is: Runtime.getRuntime().exec(“path of exe file”);

How to download the file?

You can use the below AutoIt script to handle the download popups:

We have already captured the file download popup properties like Tile, Class, Position, and Size and so on in our previous steps. Now build an AutoIt script using identified windows control:

WinWait("[TITLE:Opening ; CLASS:MozillaDialogClass]","", 10)  //Explanation – “It will wait for the title – opening , type- mozilladialogclass, for 10 secs
If WinExists("[TITLE:Opening ; CLASS:MozillaDialogClass]") Then  // if condition
WinActivate("[TITLE:Opening ; CLASS:MozillaDialogClass]")  // if that title is found it will activate and perform below actions
Send("{DOWN}")  // perform down arrow operation
Sleep(10)   // wait for 10 secs
Send("{TAB}")  // perform tab operation
Sleep(10) // wait for 10 secs
Send("{TAB}") // perform tab operation
Sleep(10)  // wait for 10 secs
Send("{ENTER}")  // press enter button
EndIf  // end of if condition

Upload pop up example:

How to upload the file?

You can use the below AutoIt script to handle the Upload window popup:

Build an AutoIt script using identified windows control:

WinWaitActive("File Upload") // enter the title of the pop up
Send("Path of the file to enter")   // enter the path of the file to upload
Send("{ENTER}") / press enter

Save and compile this script and execute that .exe file in your selenium script where we need to upload the file.

Login Pop-Up Window Example

AutoIt tutorial popup handle

How to enter username and password to the above login pop-up alert window?

You can use the below AutoIt script to handle the login popup:

WinWaitActive("Authentication Required","","10")
If WinExists("Authentication Required") Then

How to test if your AutoIt script is showing expected results or not without integrating it in your selenium script?

Follow below steps:

  • Before compiling your script double click .au3 file – it will show the errors in your script
  • If no errors are found then convert your script into a .exe file
  • Manually generate the file download pop scenario
  • Now the pop is available and click on the .exe file, it should be able to accept the pop-up and download the file

Disadvantages of AutoIT:

  • It works only in Windows operating system
  • Knowledge of fundamental coding principles is a must
  • It is great tool for professional but bit complicated for beginners

What else can we use AutoIt for?

Apart from handing windows pop-ups, we can use AutoIt to automate your each and every windows operation like file search, copy file from one location to other, installation of software and so on: Refer below examples –

The script for file search in your computer:

$search = FileFindFirstFile("*How*") // enter the search string
If $search = -1 Then // condition not satisfied show error message
MsgBox(1, "Error", "No files/directories matched the search pattern")
While 1
$file = FileFindNextFile($search)
If @error Then ExitLoop
MsgBox(4096, "File:", $file)

Save and compile this script and execute that .exe file in your current working directory. It will search all the files which start with “How” and display a message box.

Important aspects you should keep in mind while working with AutoIt:

  • Do not forget to save your script with .au3 extension
  • Compile your script and create a .exe executable file
  • The pop-up or anything that you want to handle should be present beforehand so that the .exe file can work on it


We can use AutoIt to automate anything in a Windows Operating System environment. It is a script that is written in a BASIC language and can handle any type of window pop-ups which we encounter while doing automation testing. It can kindle various things such as combinations of keystrokes, mouse movement and window/control manipulation.

Using AutoIt, we can also handle any interaction issues between Selenium WebDriver and Windows.

Here, we learned how to upload/download file pop-up, but there are also other issues such as browser authentication popup, file search in a particular directory, etc. We can handle all these issues by using AutoIt tool.

You can also write scripts through AutoIt to start a task at a particular time, to schedule a task, to copy a file from one server to another and so on.
