Spring provides a few options for building a REST client, and WebClient is recommended. Here, we are going to use the Mockito framework along with the JUnit framework. In this quick tutorial, we will look at how to unit test services that use WebClient to call APIs. Der polymorphische Stub kann dann – vom jeweiligen Datentyp abhängig – die passende Funktion aufrufen. Stub. THE unique Spring Security education if you’re working with Java today. While Mockito worked and maybe a good option for simple examples, the recommended approach is to use MockWebServer. Stub won’t though, as it basically ignores all query parameters to let you quickly stub out one or more endpoints in your route temporarily. For example, let's have an EmployeeService class with a getEmployeeById method to fetch data via HTTP using WebClient: As we can see, we need to provide a different mock object for each call in the chain, with four different when/thenReturn calls required. We can also use Spring Boot instead of using the JUnit framework.. JUnit is one of the testing frameworks used by the Java programmers for creating test cases.
