Mocking EJB injection in tests

Question

Whenever I want to test a class which uses resource injection I end up including a constructor that will only be used within the test:

public class A {

             


        

Answer 1

you could use easy gloss to that effect, it mocks the EJBs injection system.

another way is to set the field using reflexion in your tests, I sometime use something like this :

public static void setPrivateField(Class instanceFieldClass, Object instance, String fieldName, Object fieldValue) throws Exception {
    Field setId = instanceFieldClass.getDeclaredField(fieldName);
    setId.setAccessible(true);
    setId.set(instance, fieldValue);
}
