Boost Test vs. Google Test Framework: Which One Should You Choose?

21 May 2024 Stephan Petzl Leave a comment Tech-Help

As a C++ developer venturing into the world of automated unit testing, choosing the right framework can be overwhelming. With numerous frameworks available, narrowing down to the best option for your project is crucial. This article aims to provide a clear comparison between two popular C++ unit testing frameworks: Boost Test Libraries and Google Test Framework.

Overview of Boost Test Libraries

Boost Test Libraries are part of the larger Boost C++ Libraries, which are widely used in the industry. They offer a robust set of tools for unit testing, including logging capabilities. Here are some key features:

  • Integration with other Boost libraries
  • Rich set of assertions
  • XML output support
  • Flexible configuration options

Overview of Google Test Framework

Google Test Framework, also known as GTest, is another widely-used unit testing framework for C++. It is known for its simplicity and ease of use. Some of its notable features include:

  • Simple syntax for writing tests
  • Rich set of assertions
  • Support for death tests
  • XML output for integration with CI tools
  • Compatibility with Google Mock for mocking capabilities

Key Considerations

Existing Use of Boost Libraries

If your project already utilizes Boost libraries, it might be beneficial to stick with Boost Test Libraries. The integration with other Boost components, such as Boost.Log, can streamline your testing and logging processes.

Ease of Use and Compiler Messages

Google Test is often praised for its user-friendly syntax and ease of use. One significant advantage is the clarity of compiler error messages, which can be particularly helpful during the debugging process. This can save considerable time, especially in large projects with complex testing requirements.

Test Complexity

Both frameworks are capable of handling simple tests effectively. However, for more complex testing scenarios, Google Test’s compatibility with Google Mock provides additional flexibility for mocking dependencies and creating more comprehensive tests.


Choosing between Boost Test Libraries and Google Test Framework depends largely on your project’s specific needs and existing infrastructure. If you are already leveraging Boost libraries, Boost Test might be the more seamless option. On the other hand, if ease of use and clear compiler messages are your priorities, Google Test might be the better choice.

For developers seeking a no-code solution to streamline their testing processes, Repeato offers a powerful alternative. Repeato is a no-code test automation tool for iOS and Android, leveraging computer vision and AI to create, run, and maintain automated tests for your apps. Its intuitive test recorder and scripting interface make it suitable for both beginners and advanced testers. Additionally, Repeato’s upcoming web testing support will further enhance its versatility, making it an excellent choice for comprehensive testing needs.
