I need a small browser automation utility to assist with internal testing of a web reservation flow that I own/manage. The script should: Open a specific website in Google Chrome Navigate through a multi-step reservation workflow Populate form fields using configurable test data Handle client-side validation messages or modal pop-ups gracefully Proceed through the flow until the final confirmation page This tool is intended only for development and QA testing purposes to repeatedly verify UI behavior, form validation, and page transitions. Important notes: No captcha handling is required The automation should respect the website’s normal behavior and timing Clean, readable, well-commented code is required so I can modify test values later Tech Preferences Selenium / Playwright / Puppeteer (Chromium-compatible) Windows environment Google Chrome installed locally Deliverables Source code + dependencies README with setup & run instructions Short demo video or GIF showing the automated test flow reaching the confirmation page Acceptance Criteria Script consistently completes the full UI flow without manual interaction Configuration values can be easily updated Code is readable and maintainable
