• Location: Both guests joining from Paris

Laag Functionality and Workflow

• Laag Process

  • Launch script with URL and feature file
  • Computer vision used to take screenshots
  • Generates instructions transpiled into Selenium code
  • Executes tasks like clicking buttons, verifying cart items, etc.

• How Laag works

  • Start script with scenario and URL
  • Uses computer vision to reason about page content
  • Creates and runs Selenium code
  • Records all interactions and generates reusable Pytest BDD files
  • Allows regeneration of tests for interface changes
