spy constructor about mockito

[fibulwinter]

Can you provide an example of use case?

[cgarciae]

Sometime mocking things like a database driver or a graph-like structure are hard to mock because of their structural or functional complexity, you might instead prefer to use an implementation but still be able to log the objects activity.

Use case

Some script

foo (db) => db.find (...).filter.(...).map(...);

To get the test right, in find you have to tell the mock to return an object that has a filter method, that returns a object that has a map methods. Since nested structures take more effort, it might be easier to use a spy a.

Done in 0.10.0

  //spy creation
  var cat = spy(new MockCat(), new Cat());
  //stubbing - before execution
  when(cat.sound()).thenReturn("Purr");
  //using mocked interaction
  expect(cat.sound(), "Purr");  
  //using real object
  expect(cat.lives, 9);
