Continuing the topics from my last post, this week I want to offer a deep dive into the lifecycle of a Jest TestEnvironment by exposing the events that are raised when tests are run. I’ll also explore some of the details that are included with each event.

I needed a way to implement integration tests that would allow me to ensure that I could clean up the emulators I was using after each test cycle. Jest Test Environments provided a powerful way to do this, and TypeScript makes it easy to do (aside from a few quirks).

GitHub Advanced Security (GHAS) helps teams to shift left and secure their development practices. But what do you do when its process its processes and practices doesn’t quite fit your team’s approach? In this post, we’ll look at how to use GitHub Probot to implement your own process in a GitHub-native way.

Last week we built an understanding of how Kubernetes reserves resources on a node. This week we’ll look at how cloud providers configure the resource reservations for their Kubernetes offerings.

Surprised that you can’t fit as many pods on a node as you thought? Wondering why a node with 32 GiB of memory can’t hold four 8 GiB pods? It turns out that there’s a lot more to the story of how Kubernetes allocates resources. In this post, you’ll learn how resources are allocated and how to use that to plan your cluster.
