Description
This course gives you a complete, practical workflow for API testing using modern JavaScript tools. You will build a real Express API, validate every endpoint with curl, Postman, and Swagger, then automate the entire test suite with Playwright. By the end, you will understand the full lifecycle of API quality: designing endpoints, testing them manually, and running automated checks in continuous integration with GitHub Actions.
The deliverables are concrete. You will create a working API project you can upload to GitHub as part of your portfolio. You will build multiple Postman collections, a Swagger documentation site, and a complete Playwright automation suite that covers positive tests, error handling, data validation, and authentication. You will also configure a CI workflow that runs your tests automatically. These are the same types of assets hiring managers expect from strong QA engineers and SDETs.
The skills in this course translate directly to higher earning potential. API testing is one of the most in-demand skills in both manual and automation roles. Many teams rely heavily on API level validation because it is faster, more stable, and more scalable than UI automation. Engineers who understand Express, REST architecture, and Playwright's API capabilities can take on more responsibility, handle complex features, and contribute to automation frameworks. That combination typically leads to senior roles, better promotions, and stronger salary negotiation power.
This course is also forward-looking. You will use GitHub Copilot to speed up test creation, explore prompt patterns for reusable API test logic, and learn how AI-assisted workflows boost productivity. Together, these skills demonstrate that you can operate in a modern engineering environment and increase your value on any QA or automation team.
Who this course is for
■ QA engineers who want to add API testing to their skillset
■ Manual testers who want to move into automation roles
■ SDETs looking to build stronger API test frameworks
■ Developers who want structured API testing practices
■ Anyone preparing for QA or automation job interviews
■ Career changers who want practical, portfolio ready projects
