Cannot open the test case

Miscellaneous
1

Hello everyone,

I’m running Debian (Linux 12) on a google cloud VM. When I record a web scenario using the web recorder and save the script, I’m unable to open the test case associated with it. This happens to any new project I create.

The error is “Cannot open the test case”

Please help.

Thank you.

Hi @thisura, which KS version are you using? Did this happen when you open the old ones?

Step 1: Verify Tool & Environment Setup

Assuming you’re using Katalon Studio, Postman, or similar tools:

  1. Check Java Version
    Ensure you’re using a compatible Java version (OpenJDK 8 or higher).

    bash

    java -version # Should return 1.8, 1.11, etc.

    Fix: Install required Java if missing:

    bash

    sudo apt update && sudo apt install default-jdk # For Debian

  2. File Permissions
    Test cases might be saved to a directory with insufficient permissions.

    • Use ls -l to check ownership/permissions of the test case file.

    • If permissions are restrictive:

      bash

      sudo chown $USER:$USER /path/to/test/case sudo chmod +w /path/to/test/case

Step 2: Reinstall/Reconfigure the Tool

  1. Reinstall the Tool
    Uninstall the tool (e.g., Katalon Studio) manually or via package manager, then reinstall.

    bash

    sudo apt purge [PackageName] sudo apt install [PackageName]

  2. Reset Tool Cache
    Delete configuration files to reset settings:

    bash

    rm -rf ~/.config/[ToolName] # Example: ~/.katalon630

Step 3: Project-Specific Fixes

  1. Create a New Project
    Test with a basic scenario to isolate the issue:

    • Recreate the project in the tool.

    • Record a small test and save it. If it works, the original project may be corrupted.

Step 4: Advanced Checks

  1. Network/VM Configuration
    Ensure Google Cloud firewall rules allow required connections.

    • Check if the tool relies on external services (e.g., browsers, APIs).

  2. Working Directory Path
    Ensure the test case path matches the tool’s expected directory structure.
    Example (Katalon Studio):

    text

    /Project/Scripts/com.users.testcase

@thisura

Can you share the error log file?

Hello,

I can open the log by going to Help > Error log.

This opens up in the application “Vim”

Please guide me on how to save the log and share here.

Thanks.

You can find the file at <KS folder>/config/.metadata/.log

Please note that it is a hidden file. This may help if you are unfamiliar with Debian: How to see hidden files and folders in the Debian – VITUX

@thisura

You might need to install libwebkit2gtk-4.0-37. Please refer to this post

Installing libwebkit2gtk-4.0-37 worked!!

Thank you @duyluong.

I did create a web test case. Do you have any tip on how to automatically run it (Schedule) for every 3 hours?

I think you need to create another separate thread to ask for help from the comunity
