Hands-On Reactive Programming in Spring 5

Testing and debugging Project Reactor

A versatile testing framework accompanies the Reactor library. The io.projectreactor:reactor-test library offers all of the necessary tools for testing reactive workflows implemented with Project Reactor. Chapter 9, Testing the Reactive Application, covers testing techniques that are applicable to reactive programming in detail.

Even though reactive code is not so easy to debug, Project Reactor provides techniques to simplify the debugging process if it is required. As in any callback-based framework, stack traces in Project Reactor are not very informative. They do not give the exact location in our code where an exceptional situation had happened. The Reactor library comes with the debugging-oriented ...
