Leveraging APIs for smarter web testing
About Course
This course demonstrates practical approaches to combining API testing with WebUI testing to dramatically improve stability, speed, and the overall quality of your test automation. Instead of treating API and UI as isolated layers, you will learn how to make them work together as a unified strategy.
In three chapters, you will learn how to:
- Overcome common WebUI limitations by incorporating API workflows
- Quickly generate stable test data using API calls and validate it accurately in the UI
- Strengthen backend verification by combining UI actions with API checks
- Build smarter, faster, more maintainable test flows using an API-first mindset
By the end of this course, you will know how to extend your WebUI testing strategy with API-powered workflows that reduce flakiness, accelerate execution times, and provide deeper coverage across both frontend and backend logic.
To learn this course effectively, you should:
- Understand Groovy at a basic level
- Understand the concept of APIs
