public class UnnecessaryStubbingException extends MockitoException
MockitoJUnit) or Mockito session (
Unnecessary stubbings are stubbed method calls that were never realized during test execution. Example:
Notice that one of the stubbed methods were never realized in the code under test, during test execution. The stray stubbing might be an oversight of the developer, the artifact of copy-paste or the effect not understanding the test/code. Either way, the developer ends up with unnecessary test code. In order to keep the codebase clean & maintainable it is necessary to remove unnecessary code. Otherwise tests are harder to read and reason about.
//code under test: ... String result = translator.translate("one") ... //test: ... when(translator.translate("one")).thenReturn("jeden"); // <- stubbing realized during code execution when(translator.translate("two")).thenReturn("dwa"); // <- stubbing never realized ...
Mockito JUnit Runner triggers
UnnecessaryStubbingException only when none of the test methods use the stubbings.
This means that it is ok to put default stubbing in a 'setup' method or in test class constructor.
That default stubbing needs to be used at least once by one of the test methods.
