This is a more aggressively "modern" approach than my first few attempts. Apparently we can't just follow the Rule of Zero for the `Ne` matcher in particular, because if we do, one of the unit tests hits "recursive template instantiation exceeded maximum depth of 256" on Clang. Fixes #1305.
Googletest Mocking (gMock) Framework
Overview
Google's framework for writing and using C++ mock classes. It can help you derive better designs of your system and write better tests.
It is inspired by:
and designed with C++'s specifics in mind.
gMock:
- provides a declarative syntax for defining mocks,
- can define partial (hybrid) mocks, which are a cross of real and mock objects,
- handles functions of arbitrary types and overloaded functions,
- comes with a rich set of matchers for validating function arguments,
- uses an intuitive syntax for controlling the behavior of a mock,
- does automatic verification of expectations (no record-and-replay needed),
- allows arbitrary (partial) ordering constraints on function calls to be expressed,
- lets a user extend it by defining new matchers and actions.
- does not use exceptions, and
- is easy to learn and use.
