NOTE: if you suspect that this change breaks your build, it's likely that your tests depend on the exact messages of `ElementsAre()` and friends. The messages are implementation details of these matcher and are subject to change without notice. Depending on the messages is not supported. In that case, please rewrite your tests to avoid the dependency. When the array being matched is long, it can be hard for the user to find the mismatched element in the message generated by `ElementsAre()` or `ElementsAreArray()` - even though these matchers print the index of the mismatched element, the user still has to count to find the actual element and its corresponding matcher. With this change, these matchers will include the actual value and corresponding matcher in the failure message, making it easier for the user. Also make a small style improvement: now it's advised to write ``` EXPECT_EQ(actual, expected); ``` as opposed to ``` EXPECT_EQ(expected, actual); ``` PiperOrigin-RevId: 738039133 Change-Id: I3b94f7d01a6a4c92e2daf268df8cfb04a21d4294
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.
