Yep, you're missing something. new
is a static method just like any other, and you need to set an expectation for it. The confusion stems from the fact that if you hadn't explicitly defined a new
method, then Mockall would've created one, which wouldn't be a regular method, requiring expectations. If you rename new
to something else, then the problem will be more obvious.
In this case, you have two easy solutions:
- In your test, use
MockFooTrait::default
instead ofMockFooTrait::new
, or - Create an expectation for the
new
method, like this:
let ctx = MockFooTrait::new_context();
ctx.expect().returning(|| MockFooTrait::default());
let mut mock_foo = MockFooTrait::new();
Hope that helps.

Thanks, that's perfectly clear in retrospect and solves the issue!
The thought had occurred to me but I couldn't see how to create an expectation for new
before I had created the mock object. In my case, default
is a fine solution.
