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.

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.

We've just introduced three new changes to our pricing at Heroku, all designed to provide extra value to our customers and make cost estimation easier. These changes will kick in from September 1, 2023 onward:

1. Your account will no longer be charged the $10 monthly fee for Heroku CI.
2. Your account will no longer be charged the $10 monthly fee for Heroku Teams with over five members.
3. We've improved our pricing page to include hourly expenses alongside the maximum monthly costs.

Why is the Heroku pricing page changing? The Heroku team is simplifying pricing for clarity and a better customer experience.

What about Heroku Enterprise customers? Heroku CI has always been included, and...

Faster application delivery with remote teams is the key to connect with your customers, now more than ever. A few years ago, we released Review Apps with the goal of improving the application development process and team collaboration. Today, we are excited to announce the release of an improved version of Review Apps to general availability.

The new version of Review Apps provides easier access management with a new permission system, and more flexibility for complex workflows with public APIs. It also no longer needs a staging, production, or placeholder app to host its configuration and collaborator access; this independence supports easier, more flexible application development.
