Introduce testing APIs with Jest in eventonica backend, then guide participants with how to introduce the testing into their project with a walkthrough example, similar to this (no longer used) legacy testing lesson and (no longer used) legacy testing set up instructions.

Eventonica Project

Type of problem

Week 9 is an ideal opportunity for participants to practice understanding how to implement testing into their project. The week before they were exposed to testing for the first time. Note that this would come after https://github.com/Techtonica/curriculum/blob/main/testing-and-tdd/jest.md, so they have already had an intro to Jest.

Suggested Solution

• Add a file (or section) to the updated eventonica project (it may need its own directory)
• Make changes so that this file’s directions make it easy to add Jest API testing to their eventonica project.
• Give them a few examples of tests they could potentially use in their eventonica project, and then try to be explicit about what else they should cover on their own.
