Netlify
qotd is a tiny frontend application that serves a friendly, daily dashboard, which reminds you of the current day of the week and offers an inspiring quote. It interacts with several APIs (a quote-of-the-day service, the unsplash source API, the dark sky weather api and geolocation) and is intended to be a tiny reference application for end-to-end testing with Cypress.
We have a little test harness in Jest but mostly we are tested with Cypress. Example configuration for both circle and travis is provided.
Netlify is our deployment system, and runs on every commit, but it checks the cypress suite is passing before deploying to production.
