Is Selenium still relevant with growing API-first applications?

Yes, Selenium is still relevant even with the rise of API-first applications. While APIs are tested using tools like Postman or REST Assured, end-to-end testing of UI components remains essential, especially for user-facing features. Selenium allows QA teams to validate that the frontend accurately reflects backend data and functionality. Many professionals still pursue Selenium certification to enhance their skills in building UI automation frameworks. In real-world scenarios, combining API testing with UI automation provides complete test coverage. Therefore, Selenium continues to play a vital role in modern testing strategies, complementing API-level testing rather than being replaced by it.
