This repository provides three templates to use google test framework:

1. unit-test only: "code-under-test" and "test-code" mixed in same folder. There is no "user-defined main function".
   • the unit-test executable is build/mytest
2. unit-test and end-to-end simulation: "code-under-test", "test-code", "user-defined main function" all mixed in same folder. Using different file names to separate:
   • "*main.cc" or "*main.cpp": user-defined main function.
   • "*test.cc" or "*test.cpp": test-code.
   • everything else: code-under-test
     • the unit-test executable is build/mytest
     • the end-to-end executable is build/${filename} where "filename" is the name of the file that contains user-defined main function.
3. unit-test and end-to-end simulation: similar as 2, but use a dedicated folder "test" to contain all test-code. No need for specific file naming convention.
   • the unit-test executable is build/test/mytest
   • the end-to-end executable is build/mymain

For all templates, to build the code:

• cd build
• cmake ..
• make

Note: use cmake -D CMAKE_BUILD_TYPE=Debug .. to generate debug build.

** To run this in MacOS:

1. install gtest: brew install googletest
2. add Lib path via terminal: export LIBRARY_PATH=/opt/brew/lib
3. add the following to CMakeLists.txt set (CMAKE_CXX_STANDARD 14) include_directories("/opt/brew/include")
