Spring Framework Master Class - Java Spring the Modern Way - Spring Unit Testing with Mockito

The video tutorial covers writing unit tests for CDI business and DAO using Mockito. It begins with adding business logic to a class and implementing a method to find the greatest value from a list. The tutorial then demonstrates writing unit tests using Java context and explains the drawbacks of depending on the data layer. It introduces Mockito for creating mocks, allowing for testing without a full Spring context, and highlights the efficiency of Mockito tests compared to Spring tests. The tutorial concludes with creating various test scenarios and emphasizes the importance of avoiding Spring in unit tests when possible.

What is the primary purpose of using Mockito in unit tests?

• To simplify the user interface

• To replace the need for a database

• To create mocks and test business logic independently

• To enhance the performance of the application

What is the initial step in writing a unit test for a CDI business?

• Creating a new database

• Designing a new algorithm

• Implementing a user interface

• Adding business logic to the class

Why is it important to match the package when writing a unit test?

• To reduce the code complexity

• To improve the user interface

• To ensure the test runs faster

• To maintain consistency and avoid errors

What is a potential issue with depending on the data layer for unit tests?

• It enhances the test accuracy

• It increases the speed of the tests

• It creates unnecessary dependencies

• It simplifies the test process

How does Mockito help in testing the business layer?

• By creating mocks to simulate different data scenarios

• By enhancing the graphical output

• By providing a user-friendly interface

• By reducing the need for code documentation

What is the advantage of using Mockito over Spring context for unit tests?

• Mockito requires more resources

• Mockito tests are faster and simpler

• Mockito provides better graphical interfaces

• Mockito is more complex to set up

What is the role of the Mockito JUnit Runner?

• To simplify the code structure

• To replace the need for a database

• To enhance the graphical user interface

• To identify and understand annotations for mocks

What is a key benefit of using mocks in unit tests?

• They require more setup time

• They enhance the visual output

• They allow testing without actual data dependencies

• They increase the complexity of tests

Why should Spring context be avoided in unit tests when possible?

• It reduces test accuracy

• It complicates the user interface

• It makes tests run slower

• It requires more memory

In what scenario is using Spring context unavoidable?

• When testing simple algorithms

• When dealing with MVC frameworks

• When creating basic user interfaces

• When optimizing database queries
