Today, we hope to make testing Absinthe a bit easier for you. We believe that it’s a great library for writing GraphQL applications, but if you previously haven’t done much work on an Absinthe application, you might find some things a bit tricky to test.

After weeks of writing, researching and hopefully enough proofreading, we just launched a living collection of practical guides on leveraging headless browser tools (starting with Puppeteer and Playwright) for testing, monitoring, scraping, performance measuring and more. We called it theheadless.dev. This article is about the different approaches we tried in contributing ideas to the Puppeteer community, as well as the principles that guide our latest contribution.

Few things are more frustrating than slow, flaky test suites. You're ready to deploy, wait 20 minutes for CI to run, only to find that a test failure in code you've never touched is blocking you. You dig into the source and find the problem: an external API call. It works (slowly) most of the time. But sometimes the network glitches and it fails. What do you do? In this article, José Manuel shows us several techniques for removing external API dependencies from our tests.

In January 2020, the UK recorded its first case of COVID-19. The world was facing the unknown, and the only apparent way to contain the virus was for every nation across the planet to shut down. As governments across the globe planned for the unknown, organizations rapidly began seeking ways to support efforts to save lives and restart the economies of these countries. One such endeavor was the vital role technology could play in contact tracing.

It’s been more than a year-and-a-half since we started using Cypress for our automated functional testing, and it has been well worth the investment. Cypress has now become an essential part of our process to automate regression testing, which helps us ship new releases faster, with increased quality.

In Part 1, we looked at some best practices for getting started with creating effective test suites for critical application workflows. In this post, we’ll walk through best practices for making test suites easier to maintain over time, including: We’ll also show how Datadog can help you easily adhere to these best practices to keep test suites maintainable while ensuring a smooth troubleshooting experience for your team.

Here at Mattermost, our team of developers and quality assurance analysts are proud of what we build and work hard to ship a quality product on the 16th of each month. However, maintaining our high bar for quality month over month isn’t without its challenges!

Test automation helps increase development speed while reducing cost and effort. In this article, we will share how to automate testing to help keep a test automation initiative on the right track with key tips for test execution, design and maintenance for large enterprise applications.

For a website to succeed in 2020, it’s not enough for your content to be engaging. As we all spend more time online, we want websites to be fast and the experience to be seamless. Those that don’t will lose out on customers even if their content is top-notch. Cutting down on your website’s loading time is one of the best ways to improve the overall user experience (UX).
