No matter what application you're building and who your target customers are, everyone can agree that it's critical to avoid broken deployments. To aid in this goal, many tools and concepts have been invented, with Kubernetes preview environments being one of them. In this post, you'll get a deeper understanding of how preview environments work, how organizations are using them, and how you can get started yourself. But to put it simply: preview environments allow teams to deploy a version of their applications during the development process, interacting with it as if it was deployed in production.

After spending hours or even days manually testing your software, you're wondering whether there's any way to optimize this process. Well, you're right to look toward implementing test automation. However, minimizing manual labor isn't the only valid reason to do so; there are many other benefits to test automation, a few being: Test automation is an entire field in itself that can help you improve accuracy and resilience, which you'll learn a lot more about throughout this post.

You've forgotten to add frontend validation to number fields, and now people are getting an error when they enter text into those fields. However, this is an issue that's easily preventable-by implementing a proper test that checks for edge cases, but how do get started with software testing? Avoiding bugs in production is just one advantage of testing, it also helps you be more confident about your applications, opens up the potential for a full CI/CD pipeline, and much more. In this post, we'll introduce you to software testing, as well as provide pointers on how to move from beginner to advanced.
