Happo.io
React Storybook
Enzyme
Jest

We use Jest because when we rebooted our "front end" stack earlier last year, we need to have a testing solution (we didn't have any front-end tests before that!). Jest is fast and convenient and it has plenty of community support behind it. It let's us run our unit tests with Enzyme and snapshot tests.

This is an area that we are constantly reviewing to see what can be improved, both in terms of developer needs, accuracy, test maintainability, and coverage.

I'm currently exploring using React Storybook to be the record of snapshot tests and using some online services, such as Happo.io and Percy in our CI pipeline.

Cypress

When I saw the founders of Cypress introduce it in some conference I knew I found the tool we needed to start writing E2E testing. What I like about it is that it provides a comprehensive solution for the whole lifecycle of writing E2E tests for your application, from the API you need to write the tests to showing you why they fail. It's also nice that other tools/services in the testing space, like Percy, integrate with them now.

Cypress

We use Cypress because it's made browser testing simple and fast. The speed of both writing and executing the tests means that we're able to gain good coverage with minimal effort.

By building out browser tests we've been able to refactor large parts of the application and have a good degree of faith that everything is working. Next step is going to be adding Percy into the mix.
