I try to write a unit test for a class with static methods .

My tests run successfully when I use @RunWith(MockitoJUnitRunner.class) , but when I change that to @RunWith(SpringRunner.class), I get this error :

I'm using jmockit-1.26 to mock private methods of class under test. I've succeed to mock these methods by MockUp. But it is more complicated then Expectations. I'm try to use Expectations to do this. But I got IllegalStateException while running the test class.

The class under test:

I am writing an integration test between my JPA layer and the database to check the SQL I've written is correct. The real database is Oracle, unfortunately down to reasons out my control my test database has to be Derby so naturally there are some differences. For example my JPA class has the following SQL String constant

I'm writing component tests for my bean and I'm constantly getting NullPointerExceptions because of the addMessage() method from FacesContext.

I'm sure it's because of the addMessage() method, because if I delete the line the test passes. How do I mock the addMessage() method?

i'm trying to test my bean as a component itself. So that the method i want to test gets executed correctly. Therefore i'm mocking it's dependencies with JMockit. I wrote two tests, one for validating the if condition to true, so the method ends immediately and returns null.The second one for executing the code below this condition also resulting in returning null. But my code coverage tool (JaCoCo) just shows that the if condition is executed and not the code below. Session is a field in the super class ÀbstractBean. The method isLoggedIn() invokes session.isLoggedIn() and is defined in AbstractBean.
