This provides a type-safe way for an action to express that it wants to be called only once, or to capture move-only objects. It is a generalization of the type system-evading hack in ByMove, with the improvement that it works for _any_ action (including user-defined ones), and correctly expresses that the action can only be used with WillOnce. I'll make existing actions benefit in a future commit. PiperOrigin-RevId: 440496139 Change-Id: I4145d191cca5655995ef41360bb126c123cb41d3
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:
It is 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.
- Is easy to learn and use.

GoogleMock is a part of GoogleTest C++ testing framework and a subject to the same requirements.
