This is an app for writing and saving sticky notes, built with React. This was a course project in the Skillcrush React course.
I went beyond the assigned project by practicing TDD as I created this App. I utilized Jest with React Testing Library, which was a joy to work with. (It just worked, straight out of the box!) Coverage is 100%. I tried to follow Testing Library's guiding principle that "The more your tests resemble the way your software is used, the more confidence they can give you." (Kent Dodds). Accordingly, I prioritized tests that reflect the experience of visual/mouse users (as well as those that use assistive technology) over tests that utilize code identifiers hidden to the end user.
In working on this project, I discovered the Testing Playground, which was an amazing tool in helping me to choose queries that most closely resembled user experience.
