A Simple Example of GTest and GMock

Just take a note for howto utilize the GTest and GMock to test C program. All of the information is from Internet, I just leave a little comment for them.

Download and Install

• CMake
• GTest/GMock

$ git clone https://github.com/google/googletest.git
$ cd googletest/
$ mkdir build
$ cd build/
$ cmake ..
$ make
$ sudo make install

FindGMock.cmake is included in this repository.

Build & Run (Linux & OSX)

$ git clone https://github.com/Ed-Yang/gmockc.git
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make test

Test project .../gmockc/build
    Start 1: GMock-C-Test
1/1 Test #1: GMock-C-Test .....................   Passed    0.02 sec

100% tests passed, 0 tests failed out of 1

Total Test time (real) =   0.03 sec

$ ./gmockc
