None of these are strictly needed for correctness. A large number of them (maybe all of them?) trigger `-Wdeprecated` warnings on Clang trunk as soon as you try to use the implicitly defaulted (but deprecated) copy constructor of a class that has deleted its copy assignment operator. By declaring a deleted copy assignment operator, the old code also caused the move constructor and move assignment operator to be non-declared. This means that the old code never got move semantics -- "move-construction" would simply call the defaulted (but deprecated) copy constructor instead. With the new code, "move-construction" calls the defaulted move constructor, which I believe is what we want to happen. So this is a runtime performance optimization. Unfortunately we can't yet physically remove the definitions of these macros from gtest-port.h, because they are being used by other code internally at Google (according to zhangxy988). But no new uses should be added going forward.
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:
and 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, and
- is easy to learn and use.
