kube-test-env (KTE)

KTE is a Go library that makes it very easy to create a Kubernetes cluster from testing, so all you need do is run go test. It avoids having to have shell scripts that manage kind clusters. Presently it implements only one provider - kind, it may include other options in the future.

KTE does not require kind CLI installed, it just needs Docker.

It's common for test infra to be configured before tests run, that approach suffers from the following:

• setup contract is not explicit, it's often done via shell scripts and not an API
  • lack of abstraction makes it harder to migrate between infra providers
  • incidental features easy to add in a shell script
• the lifecycle of the infra is not bound to test runs
  • left-over state
  • test scenarios cannot define infra scale or isolation requirements
• configuration of the infra may not match expectations of the tests
  • leads to uncertainty and poor reliability
  • it's hard to evolve infra needs as tests evolve
