Experience
ClimQA: A Modern Front-end Testing Framework Template
https://github.com/jalolk/climqaThis framework includes comprehensive testing tools: Jest and React Testing Library support reliable unit and component testing, while Playwright enables end-to-end testing across browsers with features like network request mocking and mobile responsiveness. Organized with a Page Object Model (POM), it ensures clean, scalable tests while including strategies for accessibility and error boundary testing.
ClimQA's CI/CD pipeline is powered by GitHub Actions, handling automated testing, build verification, and code deployment to Vercel. With linting, test coverage reports, and parallel test execution, the system streamlines continuous integration for rapid iteration. This project is ideal for teams seeking a maintainable, high-quality testing setup that combines automation with a structured approach to modern front-end testing.
Play2do
https://github.com/jalolk/play2doThis project's structure is organized for easy extension, with dedicated test suites covering all application layers. Integrated with CI/CD, Play2do is an excellent resource for QA engineers and developers to learn, build, and refine testing workflows for reliable, maintainable applications.
