I have an interface, ex:
interface MyService {
void createObj(int id)
void createObjects()
}
I want to test an implementation of the createObjects
method, which has body like:
void createObjects() {
...
for (...) {
createObj(someId);
}
}
I have already tested createObj(id)
:
@Test public void testCreate() {
//given
int id = 123;
DAO mock = mock(DAO.class);
MyService service = new MyServiceImpl(mock);
//when
service.createObj(id);
//verify
verify(mock).create(eq(id));
}
So I don't want to repeat all test cases for it in the test for createObjects
.
How can I make sure that another method of the real object was called besides the one I am testing?
Use a spy:
MyService myService = new MyServiceImpl()
MyService spy = spy(myService);
doNothing().when(spy).createObj(anyInt());
// now call spy.createObjects() and verify that spy.createObj() has been called
This is described, like everything else, in the api doc .
