Arduino TestSuite: Automated Arduino Unit Tests

This Python scripts allows automated running of several Arduino unit tests. The testing process is started on the PC but the tests run on the actual Arduino hardware. One set of unit tests is typically used to test one Arduino library.

The following steps are performed for each set of unit tests:

1. The script compiles and uploads an Arduino sketch that contains the unit testing.
2. The unit tests are run on the Arduino board.
3. The results of the test are printed over the serial port and analyzed by the Python script.
4. The script starts the next test, repeating steps 1,2 and 3 for all test that are requested in the configuration file. The script prints a summary showing an overview of all the failed/passed tests in the complete testsuite.

Installation:

• Download the source and run python setup.py install
• Python Package available in the Python Package Index at: http://pypi.python.org/pypi/arduino_testsuite
• Install using pip: pip install arduino_testsuite

Usage:

• Start the program with: python -m arduino_testsuite
• Select the tests you want to run by editing: planned-tests.conf
• Getting help: python -m arduino_testsuite --help
• Post issues to GitHub http://github.com/jeroendoggen/Arduino-TestSuite/issues.

Typical test output:

user@computer:~/tests$ python -m arduino_testsuite

Requirements:

• The unit tests are written with the "Arduino Unit Testing Library": http://code.google.com/p/arduinounit
• The tests also use "Arduino Unit Testing Helper Library": http://code.google.com/p/arduino-unit-test-helper-library
• The code is uploaded to the Arduino board with "Arscons: scons script for Arduino": http://github.com/suapapa/arscons
• Python 2.6+ packages: pyserial

Limitations:

• Currently only tested on Linux and Windows 7
• The program was created with other OS users in mind, so it will eventually get full cross-platform support.
