Console logging is often perceived as a bad practice, but in specific contexts, it’s quite suitable. Consider a scenario of a workshop where printing output directly to the console enhances transparency and simplifies the project setup. Using a comprehensive logger could lead to unnecessary clutter. However, there’s a downside to directly printing to the console—it makes it challenging to verify the result. Well, at least so I thought until I accidentally stumbled upon this awesome article by Thijs Kaper. Although Spring Boot provides out-of-the-box support for output verification, it’s also possible, and sometimes preferable, to implement it independently. In this blog post, I’ll demonstrate how to create a custom spec in Kotest that you can leverage in your tests. This spec automatically captures console output and provides the result for verification.
