A fairly common desire is to simply get everything deployed and make a few queries to validate that the resulting system is operational. As you do these operations, they are frequently captured in either Makefiles or shell scripts as simple programs to validate a baseline of functionality. Several years ago, a system called Bats, which stands for Bash Automated Testing System, was developed to make it slightly more convenient to run tests using shell scripts.
There are several examples of using Bats to test systems deployed in Kubernetes. The tests are generally straightforward and easy to read, and it is easy to extend and use. You can find more information on Bats at its GitHub home https://github.com/sstephenson/bats. You may see Bats used in some Kubernetes-related projects as well, for simple validation.
Bitnami has set up an example GitHub repository to use as a starting point that uses Bats and Minikube, and was designed to also work with external CI systems...
