[200~Implement script injection and assertion functions with error ha…

[pawvan]

Summary of Changes

What I've Done:

1. Script Injection Function:

   • Added a function to dynamically inject and execute script logic within a page context. This allows for executing custom JavaScript code within the page.

2. Sanitization and Error Handling:

   • Included basic sanitization and error handling within the script execution to mitigate Cross-Site Scripting (XSS) risks. This ensures that user input is handled securely and any errors during script execution are managed.

3. Content Verification Function:

   • Added a function to verify the text content of a div element against expected values. This function checks if the content of a specific element matches what is anticipated.

4. Error Messages:

   • Enhanced error messages for better debugging and improved code clarity. This provides clearer information when something goes wrong, making it easier to identify and fix issues.
