Set up and prove testing framework (Jest and Puppeteer?)

[akc42]

I want to start a proper testing regime - might not set up tests for everything immediately, but at least anytime there is a bug I want to make sure I can set up a test which fails before the bug is fixed and doesn't when I have fixed it

• Try cypress and see if it can replace puppeteer and/or jest (possibly jest for server side?)
• Set up Jest testing environment
• Set up Puppeteer testing environment
• Figure out how to mock Ajax requests (is it in Jest or will I need Sinon?)
• Figure out how to mock HTTP so I can test server.js
• Figure out how to structure tests so I can have a test database initialised by database.sql
• Write some initial tests for server.js - particularly Initial Database Setup
• Write a test for /api/pin in server.js
• Write test that checks api token for all "logged in" requests
• Write a test that checks cid is checked for in Admin and User Apis
• Write at least one client side test

IF I use jest there are three separate test scenarios that require different approaches.

1. Server module testing - jest on its own
2. Client module testing - jest and jest-electron (An app written in electron for testing)
   3 End to end testing - jest and puppeteer.

Note there is a jest-puppeteer but it takes over jest and I am thinking I only needed it for one third of my potential testing regime, so is it appropriate?

I have also been looking at Cypress, which is able to do client and end to end testing on one package and has lots of nice features to see how tests fail. I think this is actually my first job
IF I do this server tests can use existing mocha, chai, (sinon?) setup
