Test a Render Prop!
2018-05-25
enzyme is a hugely popular library for testing React components. While
contracting for Commercetools, me and my teammates found it a bit
inconvenient to test render props with enzyme and we had plenty of them after
their epic rise in popularity.
My coworker Tobi and I built an extension for enzyme which removes the
overhead of testing render props called @commercetools-frontend/enzyme-extensions.
I wrote the "Test a Render Prop!" article as a homage to the hugely popular Use a render prop! article. It is supposed to be the missing testing section of the original.
The developers behind enzyme have since reached out to us and we
helped integrate the renderProp test helper of enzyme-extensions into the v3.8.0 release of `enzyme`, which I'm very excited about!

Work with me
As a consulant and frontend developer I help my clients build web applications. Over the last years I gained experience in versatile parts of the frontend. I worked as a UI architect, on feature teams, frontend infrastructure and as the intersection of developers and designers. The work ranged from highly technical infrastructure setup to creative work like building a Design System.
I'd love to get to know your web application to see how I can help out. I work both remotely and in-house. I usually work with React, React Native, Apollo, GraphQL, Webpack, node, and databases and services like Prisma, MongoDB and RethinkDB.
Send an email and let's find out what we can achieve together.
