This repository contains a very simple example to use GTest

• Open a terminal
• Type sh install_gtest.sh to run the script to install GTest
  • GTest will be installed inside 'thirdparty' folder.
• Type cmake . && make -j to build the project
• Type ./unitTests to run the unit test

Inside the 'src' folder, you will find a file called 'StringReturner.hpp'. This file contains a simple class called StringReturner, which has two public functions: getHello() and getWorld. Each function returns a string "hello" and "world".

Inside the 'test' folder, you will find a file called 'StringReturerTest.cpp'. This file contains a test function to test if getHello() returns "hello" and getWorld() returns "world" as intended, using GTest.

The test successfully passed.
