Selenium and PERL : File handling with AutoIT script.

 To handle file download window, develop logic and write code based on following two points.

  • First run the AutoIT script as a process.
  • Click on Link that downloads file.

When AutoIT script is running as process, it is waiting for new windows pop-up (Windows) event. When selenium code clicks on any link that downloads file, browser opens new pop-up (Windows). When AutoIt script finds new windows with specific title, it takes control and clicks button available on pop-up windows GUI.

How to create process in perl.

  • Install PERL  module Win32::Process.
  • Create exe file of your AutoIt script.
  • Assumed AutoIt is already installed on your systemperl script:
    use Win32::Process;
    # Error handling
    sub ErrorReport()
    {
    Info_Log("Info","Can not create process ","fatal");
    print Win32::FormatMessage( Win32::GetLastError() );
    }# Create Process.
    sub create_process()
    {
    my ($process, $args) = @_;
    ### $process= file to be executed as process.
    ### $args = Arguments to be passed to process.

    Win32::Process::Create($ProcessObj,
    $process,
    $args,
    0,
    NORMAL_PRIORITY_CLASS,
    ".")|| die &ErrorReport();
    return ($ProcessObj);
    }
    # Download file abce.com for your http server
    my %testdata;
    my $filetobedowmnload = "abce.com";

    $testdata{'LinkToClick'} = "http://yourserver.com/abcd/bcd/$filetobedowmnload " ;

# LinkToClick is your link name. You should use link name properly in your code.
# Here I have taken whole path of file on http server. It just for example.
&create_process("Lib\\filedownload.exe","filedownload.exe $filetobedowmnload 1 1");
# Now click on link
&click_link($testdata{'LinkToClick'});# File will be downloaded at default download folder.

#### Rest of the code....

Selenium: File download handling.

Image
 When we download any file from internet, browser opens new pop-up windows and prompt user for action. Action could be open, save or save as.  Pop-up windows ( GUI ) could be different based on browser. When you are automating file download dialog box (or action), you should keep following points in mind. -           Browser -           Pop-up windows  title -           Pop-up GUI -           Available buttons on GUI -           File Type (Binary file, zip file, MS file etc..) -           Extra settings See how IE and FF pop-ups ... If you have any doubt or if it is not working , please provide me details and I will try to fix the problem. Func Down_FF_NonMS() Send("{TAB}{TAB}...

Major Differences between Python and Java

Image
Python and Java are both popular programming languages that have been around for many years. While they share some similarities, there are also some key differences between them. Syntax: One of the most obvious differences between Python and Java is their syntax. Python is known for its simple, readable syntax, which is designed to be easy to learn and use. Java, on the other hand, has a more complex syntax that requires more code to accomplish the same tasks. Performance: Java is generally faster than Python when it comes to execution speed. This is because Java code is compiled into bytecode, which can be executed directly by the Java Virtual Machine (JVM). Python, on the other hand, is an interpreted language, which means that each line of code is executed one at a time by the Python interpreter. Memory Management: Java manages memory through a process called Garbage Collection. This process automatically frees up memory that is no longer in use, which helps to prevent memory leaks ...

Cypress V/S Selenium

  Cypress V/S Selenium During my learning of Cypress, I noted down a few important differences between these tools. Documentation: Cypress Selenium Feature Cypress Selenium Language Support JavaScript Multiple languages including Java, C#, etc. Test Architecture Mocha test runner and Chai assertion library built-in Requires separate test frameworks and assertion libraries Browser Support Chrome, Firefox, Electron Multiple browsers including Chrome, Firefox, Safari, Edge, etc. Test Structure Built-in test runner and assertion library Needs separate test runners and assertion libraries Test Execution Faster execution Slower execution due to the use of WebDriver DOM Manipulation Native commands for DOM manipulation Needs to use JavaScriptExecutor for DOM manipulation Locators Cypress uses jQuery-like syntax for selecting elements Selenium uses various locating strategies such as XPath, CSS Selector, etc. Automatic Waits Automatically waits for commands to complete before moving...
