Summary

In this chapter we learned how to:

• Write reactive test cases using StepVerifier.
• Test domain objects, which are below the layer of Reactive Streams with simple tests.
• Test reactive services using StepVerifier and mocks (courtesy of Spring Boot’s @MockBean).
• Write reactive results and verify Reactive Streams signals like complete and error.
• Write full container tests using Spring Boot.
• Test with slice testing using @WebFluxTest and @DataMongoTest.
• Write a BlockHound module to detect blocking code.
