Dependencies
Frameworks for unit testing and mocking are pulled in as git submodules.
The testing framework uses ruby and rake as well as libasan (AddressSanitizer) to generate and run code.
If you run the tests on your own machine you will have to install them.
To minimize the need for installations and configuration, use the docker builder image (bitcraze/builder) that contains all tools needed. All scripts in the tools/build directory are intended to be run in the image. The toolbelt makes it easy to run the tool scripts.
Running all unit tests
With the environment set up locally
make unit
with the docker builder image and the toolbelt
tb make unit
Running one unit test
When working with one specific file it is often convenient to run only one unit test
make unit FILES=test/utils/src/test_num.c
or with the toolbelt
tb make unit FILES=test/utils/src/test_num.c
Running unit tests with specific build settings
Defines are managed by make and are passed on to the unit test code. Use the normal ways of configuring make when running tests. For instance to run test for Crazyflie 1
make unit LPS_TDOA_ENABLE=1
