Tests

Integration tests with kubebuilder

These tests are generated by kubebuilder and use Ginkgo. They will start a controller process and api server locally.

The test (which hasn't been modified from the default) lives in feline_controller_test.go.

To run these tests:

go test ./pkg/controller/feline

End to end tests

After you have deployed the controller, you can run the integration tests against the current-context cluster in your kube config:

go test -v -count=1 -tags=e2e ./client-go/test
go test -v -count=1 -tags=e2e ./kubebuilder/test

-count=1 is the idiomatic way to disable test caching.

You can override the kubeconfig and context if you'd like:

go test -v -tags=e2e -count=1 ./client-go/test --kubeconfig ~/special/kubeconfig --cluster myspecialcluster
