Mockito Tutorial: Learn mocking with 25 Junit Examples - Step 04: Your first Mockito code! Hurrah!!!

This video tutorial introduces the Mockito framework, focusing on creating and using mocks in Java. It covers configuring Eclipse for static imports, creating mocks with Mockito, and debugging and testing with mocks. The tutorial highlights the advantages of using mocks over stubs, such as dynamic behavior and flexibility in testing different scenarios. It also provides practical steps for setting up and using Mockito in Eclipse, including configuring static imports and creating mock objects.

What is one key advantage of using mocks over stubs?

• Mocks are easier to maintain than stubs.

• Mocks require more code than stubs.

• Mocks are less flexible than stubs.

• Mocks are only used in Python.

What is the purpose of static imports in Java?

• To convert methods into instance methods.

• To increase the execution speed of methods.

• To allow methods to be used without class qualification.

• To make methods private.

In Eclipse, where do you configure static imports for Mockito?

• Window > Preferences > Java > Editor > Favorites

• File > Settings > Java > Imports

• Help > About > Java > Configuration

• Tools > Options > Java > Static Imports

What method does Mockito provide to create a mock object?

• mock()

• createMock()

• buildMock()

• generateMock()

What is a 'Nice mock' in Mockito?

• A mock that throws exceptions by default.

• A mock that returns default values for unconfigured methods.

• A mock that logs all method calls.

• A mock that requires explicit configuration for every method.

What happens when a method is called on a Nice mock without explicit configuration?

• It throws an exception.

• It returns a default value.

• It logs an error message.

• It halts the program.

How can you test different scenarios using mocks?

• By creating multiple stub classes.

• By dynamically configuring return values in the test code.

• By writing separate test scripts for each scenario.

• By using only static methods.

What method is used in Mockito to specify the return value of a method call?

• returnThis()

• defineReturn()

• setReturn()

• thenReturn()

Why is it beneficial to use mocks in testing?

• They automatically fix bugs in the code.

• They simplify the test setup and allow for flexible test scenarios.

• They make the code run faster.

• They eliminate the need for any test assertions.

What should you do to better understand the behavior of mocks in your code?

• Avoid using breakpoints.

• Read the entire codebase.

• Use debugging tools to step through the code.

• Ignore the test results.
