I am having difficulties getting PowerMock and Mockito to work.
I am using these versions. They should be compatible.
I am also using TestNG, but I do not believe this has any affect on the outcome of this test.
I want to mock an object, call a method on the mocked object, and verify that a private method was called once within the mocked objects method.
I have constructed an example, that hopefully explains what I want to accomplish.
public class MyClass {
public void execute(Object o) {
valid(o);
}
private boolean valid(Object o) {
return o != null;
}
}
This is my test class
@RunWith(PowerMockRunner.class)
@PrepareForTest(MyClass.class)
public class TestClass {
@After
public void validate() {
validateMockitoUsage();
}
@Test
public void executeTest() throws Exception {
//Initialize the Class and create the spy
MyClass myClass = PowerMockito.spy(new MyClass());
//Execute the method which I wish to test
myClass.execute(null);
//I want to verify that the private valid method was called once.
PowerMockito.verifyPrivate(myClass, times(1)).invoke("valid", anyObject());
}
}
I get the following error:
org.mockito.exceptions.misusing.UnfinishedVerificationException:
Missing method call for verify(mock) here:
-> at TestClass.executeTest(MyClass.java:14)
Example of correct verification:
verify(mock).doSomething()
Also, this error might show up because you verify either of:
final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
Mocking methods declared on non-public parent classes is not supported.

I have tried to search, but I could not find a solution for my problem. I believe this is a common error, and I am using PowerMock/Mockito wrong.
As you are using TestNG to run your test, the @RunWith annotation is ignored as it is specific to JUnit.
To make this work, you have 2 options:
Run your test with JUnit.
OR Configure TestNG so that it uses PowerMock object factory. The configuration details are pretty well explained here.
