Testing Frameworks

PlatformIO supports the most popular testing frameworks and allows you to easily switch between them using the test_framework option in “platformio.ini” (Project Configuration File).

You can mix different frameworks in the same project. For example, use a more advanced C++ testing framework with Mocks for the Native development platform to run desktop tests on a host machine and a lightweight framework, such as Unity, for running tests on the target embedded device with constrained resources.

Compatibility

Framework	Test Types	Development Platforms	Mocking
Doctest	Native	Native	No
GoogleTest	Any	Native, Espressif 8266, Espressif 32	Yes
Unity	Any	Any	No

Tip

We highly recommend using the Unity testing framework if you plan to run tests on the target devices with constrained resources. The Unity has minimal requirements and works even on the 8-bit AVR MCUs.
