How to Test Database Queries and More with Node.js

This blog post is a cross-post of the article originally published on Medium. Getting an application to work, most of the time is somewhat trivial. Enough trial and error and you have something to show off. However, as you code more, the vicious cycle of coding, breaking, and fixing chips away at your soul. Manual testing of the last few changes that you have made to your codebase always leaves a bad taste in your mouth.
