Unit Testing

Unit Testing is a software testing technique that reduces defects in the newly developed features or reduces bugs when changing the existing functionality.

PlatformIO Unit Testing allows you to segregate each part of the firmware/program and test that the individual parts are working correctly. Using PlatformIO you can execute the same tests on the local host machine (native), on the multiple local embedded devices/boards (connected to local host machine), or on both. When testing both, PlatformIO builds firmware on the host machine, uploads it into a target device, starts tests and collects the test results into test reports. The final information will be shown on the host side with informative output and statistics.

Using Remote Development you can start unit tests on the Remote Device from anywhere in the world or integrate with Continuous Integration systems.
