Mockito Tutorial: Learn mocking with 25 Junit Examples - Step 05: Stubbing variations with Mockito - Argument Matchers &

The video tutorial covers various Mockito examples, focusing on mocking the List interface in Java. It demonstrates stubbing methods to return specific values, handling multiple return values, using argument matchers, and throwing exceptions. The tutorial also compares Mockito's nice mock behavior with Easymock, highlighting Mockito's advantages. The video provides a step-by-step guide to creating JUnit tests for these scenarios, ensuring a comprehensive understanding of Mockito's capabilities.

What is one of the key features of Mockito that allows returning multiple values from a single method call?

• Single return stubbing

• Multiple return stubbing

• Static method invocation

• Dynamic method creation

Which method is used in Mockito to specify the behavior of a mock when a method is called?

• thenReturn

• when

• verify

• mock

In the context of mocking, what does the 'when' method do?

• It throws an exception

• It sets up the expected behavior of a method

• It verifies the number of method calls

• It initializes a mock object

What is the significance of the '@Test' annotation in JUnit?

• It throws an exception

• It verifies the test results

• It initializes a mock object

• It marks a method as a test case

What is the purpose of the 'anyInt' argument matcher in Mockito?

• To match any object type

• To match any string value passed to a method

• To match any integer value passed to a method

• To match any boolean value

How does Mockito handle a method call for which no behavior is stubbed?

• It throws an exception

• It returns a default value

• It logs an error

• It skips the method call

What is the default behavior of Mockito when a method is not explicitly stubbed?

• It throws a runtime exception

• It returns a random value

• It logs a warning

• It returns null or default values

What happens when a method is called on a mock object without a defined behavior in Mockito?

• The method is ignored

• The test fails

• An exception is thrown

• A default value is returned

Which of the following is a feature of Mockito's 'nice mock' behavior?

• It logs errors for unstubbed methods

• It skips unstubbed methods

• It returns default values for unstubbed methods

• It throws exceptions for unstubbed methods

How can you test if a method throws an exception in JUnit?

• Using the 'assertThrows' method

• Using the 'verify' method

• Using the 'mock' method

• Using the 'when' method
