1. Question 1. What Is Mockito? Answer : Mockito allows creation of mock object for the purpose of Test Driven Development and Behavior Driven development. Unlike creating actual object, Mockito allows creation of fake object (external dependencies) which allows it to give consistent results to a given invocation. 2. Question 2. Why Do We Need Mockito? What Are The Advantages? Answer : Mockito differentiates itself from the other testing framework by removing the expectation beforehand. So, by doing this, it reduces the coupling. Most of the testing framework works on the "expect-run-verify". Mockito allows it to make it "run-verify" framework. Mockito also provides annotation which allows to reduce the boilerplate code. 3. Question 3. Can You Explain A Mockito Framework? Answer : In Mockito, you always check a particular class. The dependency in that class is injected using m...
