Running the Application

If using TypeScript:

1. Compile the TypeScript file:

   tsc <your-file-name>.ts
   node <your-file-name>.js

If using ts-node (without compiling separately):

npx ts-node <your-file-name>.ts

📂 Where to Find the AI Generated Test Scripts ?

After running generateTestFiles(config), the following files will be created:

output.feature - This contains the generated Cucumber feature file with test scenarios.

output.ts - This is the Step Definition file that maps steps from the feature file to Playwright test actions.

📌 Location of Generated Files

These files will be saved in your project root folder or the default output directory based on your system settings.

✅ How to View the Files?

Open your file explorer and navigate to the project directory.

In VSCode or any IDE, check the left-hand file explorer.

Run the following command in your terminal to confirm the files exist:

ls -l output.*

📌 Note: You can now review and modify the generated test files before executing them.
