I’ve been working a little more on my Raspberry Pi Temperature Monitor and wanted to check out how to do some Test-driven Development. So, I started by looking into how I might write some tests and structure my code so I looked at the Python unittest documents and class documents. I also ran into this guide which was quite informative. I think it turned out alright (though I’m sure things may have evolved since 2009, when the guide was written. Like anything else, the code can be refactored and improved incrementally.
