ExUnit vs GoogleTest
Both stand on unit testing frameworks. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
ExUnit provides a free testing framework with Mix integration, assertions, configurable reporting, and concurrency across modules. Test cases within a module run in sequence.

GoogleTest offers a broad set of C++ testing and mocking capabilities, from automatic test discovery to parallel execution. Check the published compiler, platform and build-tool versions, and note the C++17 requirement for the 1.18.x branch.
