Why is PowerMock not good?

Powermock allows mocking static or final classes that can not be mocked in Mockito. It sounds great! It can mock anything that might not be the correct way of accessing objects in Java. Still, Powermock is not recommended.

Is PowerMock compatible with JUnit 5?

As your link suggests, still you can’t do power mock stuff with junit-5 directly, simply because there’s no PowerMockRunner (Extension) still available for junit-5.

Can we use both Mockito and PowerMock together?

Of course you can – and probably will – use Mockito and PowerMock in the same JUnit test at some point of time.

When should I use PowerMock?

PowerMock is an open-source Java framework used for creating a mock object in unit testing. It extends other mocking frameworks such as EasyMock and Mockito to enhance the capabilities.

Is it OK to use PowerMock?

For me, I’ve come to a conclusion that necessity of using PowerMock in a project is an indicator for bad code design. In later projects, PowerMock is not used at all. If something cannot be unit tested with Mockito then the class is refactored.

Why is mocking static methods bad?

If you need to mock a static method, it is a strong indicator for a bad design. Usually, you mock the dependency of your class-under-test. If your class-under-test refers to a static method – like java.

Can we mock final class using Mockito?

Configure Mockito for Final Methods and Classes Before Mockito can be used for mocking final classes and methods, it needs to be configured. Mockito checks the extensions directory for configuration files when it is loaded. This file enables the mocking of final methods and classes.

Can we mock constructor using Mockito?

Starting with Mockito version 3.5. 0, we can now mock Java constructors with Mockito. Similar to mocking static method calls with Mockito, we can define the scope of when to return a mock from a Java constructor for a particular Java class.

What is difference between mock and PowerMock?

Mockito is a JAVA-based library used for unit testing applications. Powermock dose the mock in more aggressive way, it uses custom class loader and manipulates class byte code so that testers can do the mock on a lot more things like static method, private method, constructors and even static initializer.

Is PowerMock and Mockito same?

The division of work between the two is that Mockito is kind of good for all the standard cases while PowerMock is needed for the harder cases. That includes for example mocking static and private methods. PowerMock is an open source mocking library for the Java world.

How do you mock a final method?

Mock Final Classes and Methods with Mockito

1. Overview. In this short article, we’ll focus on how to mock final classes and methods – using Mockito.
2. Configure Mockito for Final Methods and Classes.
3. Mock a Final Method.
4. Mock a Final Class.
5. Conclusion.

Can static method be mocked?

Mocking a No Argument Static Method 0, we can use the Mockito. mockStatic(Class classToMock) method to mock invocations to static method calls. This method returns a MockedStatic object for our type, which is a scoped mock object.

Is the Expectation Framework the same as powermock?

Developers familiar with the supported mock frameworks will find PowerMock easy to use, since the entire expectation API is the same, both for static methods and constructors. PowerMock aims to extend the existing API’s with a small number of methods and annotations to enable the extra features. Currently PowerMock supports EasyMock and Mockito.

How to create a mock object in powermock?

We can create the mock object using EasyMock but EasyMock doesn’t allow us to mock private methods. So we can use PowerMock EasyMock API extension to mock a class private methods. For stubbing private method behavior, we have to use PowerMock.createPartialMock () to get the mock object.

How to stub a private method in powermock?

After that, use PowerMock.expectPrivate () method to stub the private method behavior. Make sure to call PowerMock.replay () before writing the test code that uses the stubbed methods. For stub methods call verification, use PowerMock.verify () method. PowerMock doesn’t support JUnit 5 as of now, so I will use JUnit 4 for writing test cases.

Is there a Mockito extension for powermock framework?

Mockito extension now supports real partial mocking for private (and private final) methods (both static and instance methods) using PowerMockito.doReturn (..), PowerMockito.doThrow (..) etc
