Over the last decade, there have been notable shifts in the process of delivering source code. One of the more recent adaptations on the deployment aspect of this process has been the declarative and version controlled description of an application’s desired infrastructure state and configuration read more

How to Test Service APIs
When you're developing applications, especially when doing so with microservices architecture, API testing is paramount. APIs are an integral part of modern software applications. They provide incredible value, making devices "smart" and ensuring connectivity.
No matter the purpose of an app, it needs reliable APIs to function properly. Service API testing is a process that analyzes multiple endpoints to identify bugs or inconsistencies in the expected behavior. Whether the API connects to databases or web services, issues can render your entire app useless.
Testing is integral to the development process, ensuring all data access goes smoothly. But how do you test service APIs?
Taking Advantage of Kubernetes Local Development
One of the best ways to test service APIs is to use a staging Kubernetes cluster. Local development allows teams to work in isolation in special lightweight environments. These environments mimic real-world operating conditions. However, they're separate from the live application.
Using local testing environments is beneficial for many reasons. One of the biggest is that you can perform all the testing you need before merging, ensuring that your application can continue running smoothly for users. Adding new features and joining code is always a daunting process because there's the risk that issues with the code you add could bring a live application to a screeching halt.
Errors and bugs can have a rippling effect, creating service disruptions that negatively impact the app's performance and the brand's overall reputation.
With Kubernetes local development, your team can work on new features and code changes without affecting what's already available to users. You can create a brand-new testing environment, making it easy to highlight issues that need addressing before the merge. The result is more confident updates and fewer application-crashing problems.
This approach is perfect for testing service APIs. In those lightweight simulated environments, you can perform functionality testing to ensure that the API does what it should, reliability testing to see if it can perform consistently, load testing to check that it can handle a substantial number of calls, security testing to define requirements and more.
