When built with `--define=absl=1` under Bazel, GoogleTest
flags use ABSL_FLAG instead of GoogleTest's own implementation.
There are some minor behavior differences in this mode.
The most notable difference is that unrecognized flags result
in a flag parsing error, and are not returned to the user though
a modified argc/argv, unless they appear after the positional
argument delimiter ("--").
For example, to pass a non-Abseil flag, you would have to do
./mytest --gtest_color=false -- --myflag=myvalue
The documentation at https://abseil.io/docs/cpp/guides/flags
may be helpful in understanding the behavior.
There are some other minor differences. For example,
passing --help results in the program returning 1 instead of 0.

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.
