Summary
This chapter explored automated testing in modern software development, emphasizing quality in fast-paced delivery cycles. You learned about the test pyramid and its layers—unit, integration, and E2E tests—and their roles in ensuring software reliability. Practical examples demonstrated how to implement effective tests using tools such as JUnit 5 and Mockito for unit testing, Spring Boot’s test utilities for loading full application contexts, Testcontainers for stable and isolated integration tests, and MockMvc and RestAssured for validating API behavior at different layers.
The chapter also covered performance testing using JMeter to assess system stability and scalability and introduced TDD and BDD, which foster code quality through test-first design and business-aligned requirements using the GWT pattern.
This chapter’s theoretical concepts and practical implication strategies provided a solid foundation for developing automated testing...
