Hands-On Reactive Programming in Spring 5

Summary

In this chapter, we learned how to test asynchronous code written using Reactor 3 or any Reactive Streams-based libraries. In turn, we covered the essential points of testing reactive Spring applications, based on the WebFlux module and the Spring Test module. Then, using WebTestClient, we learned a way to verify a single controller in isolation, or the whole application with mocked external interaction. Furthermore, we learned knowing how to test Reactor 3 helps us in testing the whole system in integration. Along with everyday business logic checking, we learned a few tips for working with mocked security, which is also a crucial part of modern web applications. Finally, this chapter ended with some tips and tricks for WebSocket ...
