We need to decide with testing framework(s) to use. The only framework I know for React _Native_ apps (I've only ever used React) is [Jest](https://jestjs.io/docs/en/tutorial-react-native.html), but maybe they are other good ones..? A one stop shop with minimal dependencies would be good. [Cypress.js](https://www.cypress.io) is great for this, but unfortunately it doesn't yet support native mobile apps.
