Why?
While it is easy(ish) enough to add google test using various packages, you might want to add it directly to your project, (to debug your tests and so on).
I also found that packages are not always as often as you might want, so it might be because you need a new feature or something added to your test.
Before we start
– I am using Visual Studio 2019, but it should work fine with 2017 and even 2015
– I am using the latest Google Test (v1.10 at the time of writing this, but the principle is the same for almost all versions and should work fine for a few versions.
Getting started
- Go to Google test on Github and get the latest release, make sure you get the ‘source code’
- Don’t get it from anywhere else, you don’t know what has been changed and who changed it!
- Remember that google test is written to a test application, not your main application!
- Create a new console application, (File > New > Project …) and select “Console App”
Now add Google Test
- Download the latest release of Google test and extract it in your project folder, (of course create a sub folder of sort).
- In your project, create a new ‘folder’, I normally prefer to have it mirror what it looks like in my actual windows source code directory, but you could call it whatever you want, (like I did below).
- Right-click on the ‘src’ folder and select “Add > Existing Items…”
- Navigate to the folder you extracted, and find the ‘googletest > src’ folder
- And then select ‘gtest_main.cc’ and ‘gtest-all.cc’, nothing else.
- Finally, right-click your project and select “properties” and edit the “Additional Include Directories”
- Add the directory relative to the location of your solution
You could enter the full path if you want, (but that … blah), or you could use macros …
Either way, make sure that the path is valid.
- Make sure that the changes you make apply to all your build configuration.
In the screenshot above I havex64andReleasebut make sure that you choose all the configurations you will be using. - Compile your code … nothing funny should happen, (’cause you did nothing really).
If you get an error, double check your paths and permissions.
Write and run a test
Last but not least, write a very simple test in your main and run a test
You do the rest
Now that a simple test is running, you can start creating tests for your own project.

#include <gtest/gtest.h> TEST(EngineString, Basic) { const auto data = "abcdefg"; ASSERT_EQ(data, u"abcdefg"); } int main(int argc, char **argv) { ::testing::InitGoogleTest(&argc, argv); return RUN_ALL_TESTS(); } |
Example?
Have a look at my directory watcher project and see my own tests.
As an aside, I am alway looking for comments, reviews and so on, please have a look at the project and comment!
