Kubernetes (K8) is a powerful open-sourced system for deploying, scaling and managing containerized applications. The highly versatile system allows developers to scale applications up or down based on their needs. It adjusts to changes in demand, enabling applications to accept substantial traffic without any issues.

There are countless benefits to using Kubernetes. With Kubernetes API testing, developers unlock even more potential and greater capabilities in creating game-changing applications.

About API Testing

The Kubernetes API allows developers to query and manipulate the state of objects within the Kubernetes staging cluster. It makes performing preview and integration tests a breeze. Instead of dealing with the downstream effects that small changes can have, developers can enjoy high-fidelity testing with live dependencies and data.

API testing can involve the creation of sandboxes. The sandboxes run a branch version of microservices. Developers can then preview changes and run automated tests to catch regressions before merging. It makes previewing changes from mobile and web front ends easier and eliminates the guesswork. Kubernetes API testing can occur on every pull request, creating a more efficient workflow and the ability to prevent regressions early.

Benefits

The biggest reason to do API testing in Kubernetes is to improve productivity. Code changes can have major rippling effects on containerized applications. Even seemingly minor adjustments can impact front-ends and user experiences in major ways.

With testing, developers can preview and test those changes before merging. It allows developers to catch integration issues early, ensuring that changes don't have major impacts. If integration issues need attention, developers can easily spot what they are. That means no more sifting through code to try and find the problem.

API testing is also scalable without creating runaway infrastructure costs. The testing sandboxes are lightweight and efficiently use staging clusters. They cost up to 100 times less than traditional methods of replicating test environments.

That means developers can test at scale, working more efficiently without additional costs.

Finally, API testing is a great avenue for collaboration. Preview new features, share work with others and tackle parallel development.
