mcp23s17-wiring's Issues

I ❤️️ the tests!

I just have to say, fantastic job creating tests for this library! I'm always looking for good examples on how to do that.

If you're ever looking for techniques for offline testing of Particle apps, feel free to take a look at some of the apps I wrote for my Carloop project.

https://github.com/carloop/app-reminder/blob/master/tests/app-reminder-tests.cpp

I use Catch, a single header file testing framework and run the main loop inside the test to do integration style testing of the app.

Anyway, I just wanted to say thanks for making high quality libraries and for contributing to the Particle ecosystem!
