What is Pitest? Pitest is a library that helps us do mutation testing. Mutation testing is a process in which random variations of the code under test are generated. Hence, our tests will run against variants of the code that we’re intending to test. If the test fails, the mutation is killed, if it still passes it lives. So in …

I attended the JavaLand conference in March, stumbled upon the Gradle booth, and found this gem: Of course, at some point, a fanboy hijacked the thread and claimed the so-called superiority of Gradle. In this post, I’d like to shed …

My original approach with my JEP proposal was to build a replacement of the API, which could be used as a drop-in for …

In this tutorial, we will take a look at working with GitLab Merge Requests inside IntelliJ IDEA. When reviewing Merge Requests in a web interface, we don’t have the same support that our IDE gives us, like syntax highlighting and the context within which the code was written. IntelliJ IDEA has support for reviewing and merging GitLab Merge Requests. These …

An easy non-obtrusive way to collect data about your dockerized app without changing your existing docker-compose.yml or docker files! This is just a neat trick that I discovered when I was trying to collect OTEL data about my application which was running via Docker Compose. I was trying to understand more about the code using tracing. However, I definitely didn’t want to modify …
