Types

type ClusterFeature 

type ClusterFeature string

ClusterFeature represents a feature that can be enabled or disabled on the target Kubernetes cluster.

type Framework 

type Framework struct {
	// ClusterFeatures is a map indicating whether specific
	// cluster features have been detected in the target cluster.
	ClusterFeatures map[ClusterFeature]bool

	// FeatureMap is the map containing features and their status for the current instance of the end-to-end test suite.
	FeatureMap features.FeatureMap

	// KubeClient is an interface to the Kubernetes base APIs.
	KubeClient kubernetes.Interface

	// Namespace is the namespace in which we are running.
	Namespace string

	// NatsClient is an interface to the nats.io/v1alpha2 API.
	NatsClient natsclient.Interface
}

Framework encapsulates the configuration for the current run, and provides helper methods to be used during testing.
