Abseil Team 3fa7f983c6 Shut up a Clang warning.
Clang warns on this pattern because it looks like the author might
have meant to use the value of the first part of the comma operator,
so it warns that it isn't being used. The cast here signals to Clang
that this behavior is intentional.

This was discovered while updating gmock in Android. Clang's -Wcomma
warning is on by default with either -Wall or -Werror, so users of
gmock with those on in combination with -Werror are unable to build
without this fix.

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.
