Learning cmake and googletest using VScode.

Notes:

• Reference link: https://www.hahack.com/codes/cmake/
• Some remarks: (1) Case_i related to the Demo in the reference link; (2) For Case3: the MathFunctions.h file use "extern" keyword; (3) For Case4:
  • Write config.h.in file to generate config file;
  • Include "config.h" in main.c
  • Modify main.cc to choose different library
  • Use ccmake . // c // enter // g // make to run (4)For Case5: (make install/test)
  • sudo make install
  • Copy .o file to /usr/locol/bin
  • Copy .h file to /usr/local/include
  • check: ls /usr/local/bin
  • note this copy path can be modified (5)For Case6:
  • similar to Case4

Notes: (1) Gtest_one_function: - test.cpp & a.out - include the gtest TEST functions and function define to test.cpp function - refer to: https://blog.csdn.net/qq_26915769/article/details/107028696 - using command line run: g++ -std=c++11 test.cpp -lgtest -lpthread ./a.out - gtest download in /usr/local/include - change the c_cpp_properties.json file to include this folder: "includePath": [ "${workspaceFolder}/**", "/usr/local/include" ] (2) simpletest: - using the CMakeLists to compile and link the gtest library - include the gtest TEST functions and function define to main.cpp file (3) Gtest_class: - test calc class with add function - class defination using hpp file and using #program once to set include guard - note the complie way shown in calc_test.cpp (4) Gtest_setup_teardown - g++ main.cpp -o test -std=c++11 -lpthread -lgtest - ./test - If we use setup and teardown funcion, we need to define a class form Environment Setup and Teardown for the environment run firstly for the whole file Every setup function in testsuite need obey the rule setting in Environment setting - The teardown function is not necessary - TEST_F(test_suite_name, test_case_name): one test_suite can have many test_case - Define TestMap from test class for SetupTestcase and Setup SetupTestcase for the suite TestMap Setup for the testcase in TestMap
