Steps to setup Google Test Framework in my Linux workstation (running Ubuntu):

1. sudo apt-get install libgtest-dev

2. sudo apt-get install cmake # install cmake cd /usr/src/gtest sudo cmake CMakeLists.txt sudo make

   copy or symlink libgtest.a and libgtest_main.a to your /usr/lib folder

   sudo cp *.a /usr/lib

3. Create TEST functions: TEST(FindNumOccurance, General) { // create test arrays int arr1[1] = {1};

   EXPECT_EQ(1, find_target_number_occurance(arr1, 0, 0, 1)); ...//more EXPECT function }

4. Create CMakeLists.txt: For example: cmake_minimum_required(VERSION 2.6)

#Locate GTest find_package(GTest REQUIRED) include_directories(${GTEST_INCLUDE_DIRS})

#Link runTests with what we want to test and the GTest and pthread library add_executable(runTests recursion.cpp) target_link_libraries(runTests ${GTEST_LIBRARIES} pthread

5. Compile and run tests:

• cmake CMakeLists.txt

• The following files should be created after running cmake: CMakeCache.txt CMakeFiles cmake_install.cmake Makefile

• run "make": make

• run the google unit test: ./runTests
