Testing

The default scaffolds in Phoenix do not show how to use setup_all and other niceties in your tests. This article shows you how: http://blog.lucidsimple.com/2016/01/31/exunit-cheat-sheet.html

describe and setup blocks.

	A friend of mine, approaching 50, works as a programmer in a medium sized consultancy. In a recent conversation he told me how he felt like he was feeling older now that they had hired many 20-somethings in his company.
