Kotlin Test Automation: Web, Mobile, and API Testing

As software systems become more complex, automated testing is essential for delivering reliable applications at speed. Kotlin has emerged as a powerful, expressive language not just for development, but for building modern, highly maintainable test automation frameworks. This text-based course guides you from the fundamental concepts of QA automation to designing and running comprehensive test suites. You will learn how to leverage Kotlin's elegant syntax and powerful ecosystem to automate tests across web interfaces, mobile platforms, and backend APIs. What you'll learn: - Understand foundational QA automation concepts, testing terminology, and the structure of a test suite. - Write clean Kotlin code specifically tailored for test scripts, utilizing modern language features and type safety. - Configure test environments using Gradle with Kotlin DSL for seamless dependency management. - Build automated tests for web applications using Selenium and mobile apps using Appium. - Implement asynchronous test patterns and handle concurrency safely using Kotlin coroutines. - Apply MockK and JUnit 5 to mock dependencies and write robust integration and API tests. The course begins with essential testing terminology and Kotlin basics before moving step-by-step through web, API, and mobile automation. You will progress from simple assertions to structuring scalable, multi-platform test frameworks using industry-standard libraries. This course is designed for manual QA engineers looking to transition to automation, as well as beginners with basic programming exposure who want to specialize in Kotlin-based testing. No prior automation experience is required. Start reading today and build the skills needed to become a modern test automation engineer.
