Testing reactive components
In this section, we’ll delve into testing reactive components, focusing on the UserController endpoints in our sample reactive Spring Boot application. Testing reactive components is slightly different from traditional applications because reactive programming offers a non-blocking, event-driven approach to handling data streams and the propagation of change. We’ll use Spring WebFlux along with WebTestClient for testing reactive HTTP requests.
Setting up the testing environment
As we learned in Chapter 3, reactive programming in Spring, facilitated by Spring WebFlux, introduces an approach to a non-blocking, event-driven model that efficiently handles asynchronous data streams. That’s why we need a slightly different strategy to test these reactive components to ensure that the asynchronous and non-blocking behavior is accurately accounted for. The reactive testing environment must be capable of dealing with data flows and sequences...
