3 Tests tests are written using the [ArduinoUnit](https://github.com/mmurdoch/arduinounit) library (version 2.0).
5 Follow the instructions in the [ArduinoUnit readme](https://github.com/mmurdoch/arduinounit/blob/master/readme.md) to install the library.
7 Compile and upload the test sketch as you would any other sketch. Then open the
8 Serial Monitor to view the test results.
10 If you make changes to Firmata.cpp, run the tests in /test/ to ensure
11 that your changes have not produced any unexpected errors.
13 You should also perform manual tests against actual hardware.
