In this post, weโll explore how to use GitHub Copilot to generate Java code and unit tests with minimal manual input. Using a real-world exampleโa mortgage calculator serviceโyouโll see how Copilot can help write both the core logic and the corresponding unit tests. Whether youโre new to AI-assisted development or curious about Copilotโs capabilities in a Java environment, this tutorial will give you practical insight into how it worksโand where human oversight still matters.
Security is the cornerstone of software built for regulated industries. Applications must work properly and meet strict compliance standards while protecting sensitive information at every stage. In healthcare, finance, and other regulated fields, secure Java development ensures data is safe, trust is maintained, and legal obligations are met. At Keyhole Software, we help teams build security into every part of …
Let’s get this out of the way: I love tmux. Gaining the ability to multi-task within the terminal was a monumental productivity boost for me, and if you’ve used it in the past, you probably have similar stories about how it leveled up your workflow. It’s fast, it’s well-supported, and it has a plethora of features you can invoke with just a few keystrokes.
…and personally, I can only remember about a dozen of them.
As discussed in a previous blog post, Selenium is a popular choice for automation testing, and when you pair it with Cucumber, you unlock even more benefits. By writing test cases in Cucumberโs human-readable format, teams can improve clarity, boost maintainability, and make collaboration easier โ even for non-technical stakeholders. In this post, Iโll walk you through how to integrate Cucumber with Selenium to create efficient, effective tests that set your team up for success.
In my last post, โIntroduction to Web Apps with Next.jsโ, we went through the steps of setting up a new Next.js project, customizing a landing page, and implementing a very simple web application. In this post, weโll implement an Open Authentication (OAuth) based Single Sign-On (SSO) API within Next.js using NextAuth.js. Weโll be using GitHub as our provider, but the steps here are very similar for other platforms, such as Google or Discord. This will allow us to place portions of our website behind a login screen, restricting access to certain content or APIs for anonymous visitors.
