Types

type Config 

type Config struct {
	// SkipNamespaceCreation sets whether to skip creating a namespace. Use this ONLY for tests that do not require
	// a namespace at all, like basic sanity or other global tests.
	SkipNamespaceCreation bool
	// SkipControllerPodLookup sets whether to skip looking up the name of the cdi controller pod.
	SkipControllerPodLookup bool
}

Config provides some basic test config options

type ExecOptions 

type ExecOptions struct {
	Command []string

	Namespace     string
	PodName       string
