How can I unit test Arduino code?

Question

I\'d like to be able to unit test my Arduino code. Ideally, I would be able to run any tests without having to upload the code to the Arduino. What tools or libraries can he

Answer 1

You can unit test in Python with my project, PySimAVR. Arscons is used for building and simavr for simulation.

Example:

from pysimavr.sim import ArduinoSim    
def test_atmega88():
    mcu = 'atmega88'
    snippet = 'Serial.print("hello");'

    output = ArduinoSim(snippet=snippet, mcu=mcu, timespan=0.01).get_serial()
    assert output == 'hello'

Start test:

$ nosetests pysimavr/examples/test_example.py
pysimavr.examples.test_example.test_atmega88 ... ok
