Hello,
First of all, thanks for an amazing mocking library for Rust 🙂 The usage is really simple, docs are nice and it is really powerful, although I am still discovering the range of features available there.
I started learning Rust few weeks ago, so I apologize in advance for any novice issues or non-Rusty thinking 🙂
I am trying to find a way how to write an incremental tests using the mockall library. For example when I am developing some functionality of specific trait that is using another trait methods inside it, using the TDD, I start with implementing some specific functionality of a method. I setup some expectation that inside that method the method of the other trait is called. Then I implement the functionality to get the test passing. Then I continue with implementing another functionality of the same method. I want to add another call of the trait in that method, so I add another test and some new expectation. But here comes the problem as I always need to setup all expectations that will be called. In this case I will need to modify the previous, already implemented tests which is definitely not the TDD flow how it's supposed to be.
Therefore I would like to know, if there is some possibility how to turn on something like "relaxed" expectations matching - ignore calls that are not explicitely listed in the tests code. For me this was the essential part of the mocking frameworks so far, coming from the C++ (google mock) and C# (moq, ...) environment.

Well, Mockall certainly can't ignore unexpected method calls. After all,
you need to set return values. But if you don't specify any .times(),
then any number of calls, including zero, will be accepted .
