![]() PowerMockito.when(spy.staticMethod(paramIfAny)).thenReturn(value) įor the demo, we will mock the Service.staticMessage() method which is a static method in the Service class. Static spy = PowerMockito.spy(new Static()) Mockito.when(Static.staticMethod(paramIfAny)).thenReturn(value) Use PowerMockito.spy() to mock a specific static method.Use PowerMockito.mockStatic() to a mock a static class or all the static methods in a class.Mocking a Static Methodįor mocking static methods, PowerMock provides two approaches: ![]() JUnit 5 introduced new features and approaches to testing compared to the older JUnit 4 version that. As a Java developer, we work on very different areas, starts from writing core Java code to creating JSP pages, writing REST APIs. JUnit, Selenium, REST-Assured, Spock framework, etc. For example, in the given declaration, PowerMockito will prepare all classes within the specified package for mocking. In this post, I would like to focus on unit testing in Java with the JUnit5 library. Companies generally prefer programmers who are good at writing unit tests and show good knowledge of various unit testing frameworks, libraries, and tools e.g. In we can pass the fully qualified names of types we want to mock. ![]() We will be mocking and testing these methods. To eliminate unnecessary complexity, we are simply returning a String value from these methods. We are creating a simple class that has one private method, one final method and one static method. It is important to include the compatible versions of Mockito and PowerMock to avoid any possible runtime issues. If you plan to use its reflection module, for example invoking the private methods, then we need to import powermock-reflect module as well.
