Fix `-Wgnu-zero-variadic-macro-arguments` in GMock

Passing zero arguments to the variadic part of a macro is a GNU
extension and triggers warnings when build projects using GMock with
`-pedantic`.

 - Fix uses of `GMOCK_PP_INTERNAL_16TH` to always receive at least 17
arguments. (this was triggered when `GMOCK_PP_NARG` or `GMOCK_PP_HAS_COMMA`
were used with an argument containing no commas).
 - Fix `GMOCK_PP_HEAD` to append a dummy unused argument so that
`GMOCK_PP_INTERNAL_HEAD` always has two arguments.

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.
