 ## Unit tests
+Some of the software components used in the altimeter have unit tests written for them using the googletest
+framework. Those are located in the `test` folder and separated into the `common` and `embedded` tests and
+can be executed through the PlatformIO UI.
+
+The `common` tests are tests of software components that have been written in a way as to not depend on
+the features present on the microcontroller and can therefore be tested on a desktop machine or the
+microcontroller directly.
+
+The `embedded` tests on the other hand can only be executed on the microcontroller.
+
+To add a new set of tests, simply create a new `.cpp` file in the respective testfolder and prefix it with
+`test_`. Testcases written in this file will automatically be picked up and executed. Tests executed on a
+desktop machine may require adding the tested source code to the `build_src_filter` in the `platformio.ini`
+file.
