How to mock an enum singleton class using Mockito/Powermock?

Question

I am unsure on how to mock an enum singleton class.

public enum SingletonObject{
  INSTANCE;
  private int num;

  protected setNum(int num) {
    this.num =         


        

Answer 1

In addition to above Matt Lachman answer, create a object factory for power mock in SingleTonConsumerTest.class

@ObjectFactory
public IObjectFactory getObjectFactory() {
    return new org.powermock.modules.testng.PowerMockObjectFactory();
}

This will remove Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types error.
