How to Mock Constructors for Unit Testing using Mockito

Date: 2024-01-18

This tutorial demonstrates how to unit test constructors in Java using Mockito and PowerMockito. Mockito, a popular mocking framework, can mock parameterized constructors directly. For more complex scenarios, PowerMockito extends Mockito's capabilities, allowing mocking of constructors, static, and final methods. The article provides examples using both libraries, highlighting the necessary annotations (@RunWith, @PrepareForTest) for PowerMock and showcasing the simpler Mockito approach. Choosing between them depends on project needs and complexity. Constructor mocking improves unit test reliability and helps ensure code stability.
