 # Automated Test Environment for AKS Applications
 
-Framework to create Automated Test Environment using [kind](https://kind.sigs.k8s.io/) for testing Azure Kubernetes Service (AKS) based applications in CI (Continuous Integration) Pipeline (Azure DevOps), where required dependencies/infrastructure will be provisioned for executing automated tests and deprovisioned after completion.

+
+Testing the applications to be deployed over Kubernetes means either the Cluster is already available or is to be deployed on the go before you test, in former case its a cost to keep the Cluster live and in later it takes a lot of time to bring up the kubernetes cluster.
+
+ This framework uses [KIND](https://kind.sigs.k8s.io/) which itself was primarily designed for testing Kubernetes itself. KIND is often used by developers to test their applications in local dev environments and can very well be used for automated testing.
