The test class uses the MockitoJUnit.rule() method to create a MockitoRule instance. The MockitoRule instance is then used as a JUnit rule in the test class. The MockitoJUnit.rule() method returns a MockitoRuleBuilder instance. The MockitoRuleBuilder class has a strictness() method that takes a Strictness enum value as an argument. The Strictness enum has 3 values:30The org.mockito.quality.Strictness enum is used to specify the strictness level for the MockitoRule instance. The MockitoRuleBuilder class has a strictness() method that takes a Strictness enum value as an argument. The Strictness enum has 3 values:
