In Visual Studio 2017 version 15.5 and later, Google Test is integrated into the Visual Studio IDE as a default component of the Desktop Develoment with C++ workload. To verify that it is installed on your machine, open the Visual Studio Installer and find Google Test under the list of workload components:
In the Test Project Configuration dialog that appears, you can choose the project you want to test. When you choose a project, Visual Studio adds a reference to the selected project. If you choose no project, then you need to manually add references to the project(s) you want to test. When choosing between static and dynamic linking to the Google Test binaries, the considerations are the same as for any C++ program. For more information, see DLLs in Visual C++.
From the main menu, choose Tools | Options | Test Adapter for Google Test to set additional options. See the Google Test documentation for more information about these settings.
In your test .cpp file, add any needed
#include directives to make your program's types and functions visible to the test code. Typically, the program is up one level in the folder hierarchy. If you type
#include "../" an IntelliSense window will appear and enable you to select the full path to the header file.
You are now ready to write and run Google Tests. See the Google Test Primer for information about the test macros. See Run unit tests with Test Explorer for information about discovering, running, and grouping your tests by using Test Explorer.
