Testing with Jest

• Use eslint-plugin-jest to enforce testing style
• Use testing-library/jest-dom and jest-community/jest-extended for supplemental expectation matchers
• Use React Testing Library for testing React components
• Use React Hooks Testing Library for testing React Hooks
• Use User Event for simulating DOM events on React components under test
• Use Fishery for building factories
• Prefer placing test suite files alongside source files (e.g. Thing.tsx / Thing.test.tsx)
• Prefer writing specific unit tests over Snapshot Testing
• Prefer describe and it blocks over test blocks
• Prefer .resolves/.rejects over awaiting promises in tests
