Mocking IOs #82

Closed T81 closed 5 years ago

T81 commented 6 years ago

Is there any way to mock digital or analog signals?

wmacevoy commented 6 years ago

ArduinoUnit does not provide that support directly. How are your running ArduinoUnit? If you are "en vitro" then you can provide your own. Simavr (simduino) can provide digital signals. "en vivo" (on the board) requires a bit of refactoring (of the code you are testing) to test with mocks. Can you explain more?

I am writing a library for driving motors. At some point I am reading some digital inputs and analog inputs. I would like to mock these inputs to certain values in some way if possible. I do not know if I made this clear enough. I'll also check simduino.

Might be helpful. If you are willing to have some runtime overhead, mocking is usually done with polymorphism, if that means anything to you. The template style make the real implementation not have any overhead, which is better in many embedded situations...

Thank you very much! I'll have feedback in a couple of weeks or so. Also I will upload the library and the unit tests to GitHub. Currently I am working with the wiki: https://github.com/L298/wiki You can find the unit tests here: https://gist.github.com/T81/fbe0a2f0d61f9fb7c67bf5fa384b3545
