Lighthouse
🔦 Lighthouse Performance Automation (WebdriverIO)
This module automates performance testing for key Toolstation NL web pages using Lighthouse and WebdriverIO. It validates that the performance of each page is above a defined threshold.
📁 File: LightHouse.js
The LightHouse class extends a custom WebdriverIO Page helper and defines structured performance tests for NL-based pages.

▶️ Run Command
To run only the Lighthouse performance tests (identified by group ID LP), use:
npx wdio --mochaOpts.grep LP
This will execute only the performance group specified by the params.page.id value (LP).
✅ Compatible ChromeDriver
Lighthouse tests require a recent version of Chrome. Ensure your project uses the latest compatible ChromeDriver:
"chromedriver": "^137.0.1",
Install the latest version with:
npm install chromedriver@latest --save-dev
This keeps your ChromeDriver version aligned with the latest Chrome browser updates.
📌 Notes
- You can extend this module to support UK or other locales by adding new groups and URLs.
- Lighthouse reports can be enhanced with reporting tools like Allure or Mochawesome.
- Tests can be run headlessly via WebdriverIO for CI/CD integration.
