Testing a React App in Chrome with Heroku CI

When building web applications, unit testing your individual components is certainly important. However, end-to-end testing provides assurance that the final user experience of your components chained together matches the expected behavior. Testing web application behavior locally in your browser can be helpful, but this approach isn’t efficient or reliable, especially as your application grows more complex.

Ideally, end-to-end tests in your browser are automated and integrated into your CI pipeline. Every time you commit a code change, your tests will run. Passing tests gives you the confidence that the application — as your end users experience it — behaves as expected.

Updating Twelve-Factor: A Call for Participation

How to Use pnpm on Heroku

What is pnpm?

Pnpm is a fast, disk-efficient Node package manager used as an alternative to npm. The Heroku Node.js buildpack now supports pnpm. Early Node.js application owners who’ve taken advantage of pnpm support have seen 10-40% faster install times compared to NPM on Heroku deployments. It’s an excellent choice for managing packages in the Node.js ecosystem because it:

Improved Browser Testing on Heroku with Chrome

For developers and businesses offering a web-based product, automated browser testing is a critical tool to ensure continuous delivery of a reliable service. Developers write browser tests by scripting actions against a real browser, simulating real usage by navigating, selecting, and making assertions about web pages and their document elements.

In this post, we introduce a new community buildpack that helps with automated browser testing. The new buildpack resolves installation reliability problems in the existing Chrome browser buildpacks for Heroku apps.
