How to use lenient method of org.mockito.Mockito class

Best Mockito code snippet using org.mockito.Mockito.lenient

What is `UnnecessaryStubbingException` in Mockito?

By default, Mockito 3.0+ enable strict strubbing. Strict stubbing ensures that redundant test code is minimal by raising an exception - UnnecessaryStubbingException, when an unused stub is declared or a stub is declared twice.

Examples


1Mockito.when(mockObject.someMethod()).thenReturn(1);
2Mockito.when(mockObject.someMethod()).thenReturn(2);

In the code above, the someMethod is stubbed twice, which is unnecessary and would trigger the UnnecessaryStubbingException. To avoid this, you should only stub a method once and only if it's necessary for your test case.


1MyClass mockObject = Mockito.mock(MyClass.class);
2Mockito.when(mockObject.someMethod()).thenReturn(1);

In this code, the method someMethod is stubbed, but it's not called in the test case. This results in an unused stub, and causes the exception to be raised.

What is lenient stubbing?

To bypass strict stubbing, stubs can be configured as lenient which will not raise the exception. These stubs won't be checked for potential stubbing problems, such as the unnecessary stubbing.

Example


1MyClass mockObject = Mockito.mock(MyClass.class, Mockito.RETURNS_SMART_NULLS);
2Mockito.lenient().when(mockObject.someMethod()).thenReturn(1);

In this example, mockObject is created as a lenient mock. This bypasses the strict stubbing checks.

Keep in mind that lenient mocks should be used with caution, as they can hide potential problems in your test code. It's best to use strict mocks (the default behavior in Mockito) and only use lenient mocks if necessary.
