As a testing advocate, I frequently delve into “implementation details” and “public interfaces.” These terms refer to the inner workings of your API and how it’s presented to users. Rather than just defining them, let’s explore their significance through a real-world example. Witness how grasping these concepts enhances our code in practical scenarios. Once Upon […]
Tauri is a desktop apps framework built with Rust for its backend and JavaScript for its front end. The first thing I like to do in a project is set up a unit tests infrastructure. I found it surprisingly easy to do it in Rust. It has become a summer tradition with my son: we […]
Here’s how we made our website load 97.5% faster by using service workers, how we ensure the users will get the newest version every time, and how you can do it too. Our website is more than 1 year old. It started from a few static pages and has grown to a fully-fledged documentation with […]
My talk from JFokus 2023. I spoke about the main building blocks of a CI/CD process with github actions.
In 12 minutes, I shared with my colleagues three tips I used to refactor tests of legacy code. Testing the API, ensuring the tests fail for the right reason, and avoiding the coupling pitfall are exhibited in this live session.
How do I approach a new feature in an open source project? How do I TDD a frontend feature? What do we use for cross-browser testing? All this and more in this live coding session recording This is the recording of the first live session. I developed a feature taken from the issues list on […]
How and when to run Github Actions jobs on your own machine? In a previous blog, I wrote about using your own Docker images with Github actions. One of the comments was about contacting private or custom docker registries (like Amazon’s ECR). It also mentioned Self Hosted runners as a means to run on your […]
Vivid, Vonage’s design system, is now published. What better way to celebrate Vivid’s public birthday than to build a birthday quiz? Let’s have a vivid birthday! Vivid is an open-source vanilla JavaScript design system built upon the web components technology. It holds a growing repertoire of web components that a developer can use regardless of […]
How do you know your test is effective? How do you know your test protects you from breaking changes? And how can you do TDD without doing TDD? The best distillment of TDD taken from a TDD workshop in JFokus. We all know that tests are good, right? Reduce regressions, and increase confidence. If done […]
How can tests be your best documentation? What small changes can improve the contract between your code and its consumers? Learn how to improve your tests from a real-world example. Yes, we write them to ensure fewer things break before you push changes (a.k.a regression). The thing is – tests can be more than just […]
