	// DefaultData contains the default data of the configmap deployed by pkg/applications/helmclient/testdata/examplechart chart.
	DefaultData = map[string]string{"foo": "bar"}

	// DefaultDataV2 contains the default data of the configmap deployed by pkg/applications/helmclient/testdata/examplechart-v2 chart.

Functions

func AssertContainsExactly

func AssertContainsExactly[T comparable](t *testing.T, prefixMsg string, actual []T, expected []T)

AssertContainsExactly failed the test if the actual slice does not contain exactly the element of the expected slice.

func CheckConfigMap

func CheckConfigMap(t *testing.T, ctx context.Context, client ctrlruntimeclient.Client, ns *corev1.Namespace, expectedData map[string]string, expectedVersionLabel string, enableDns bool)

CheckConfigMap asserts that configMap deployed by helm chart has been created/ updated with the desired data and labels.

func CopyDir

func CopyDir(source string, destination string) error

CopyDir coypy source dir to destination dir.

func CreateNamespaceWithCleanup

func CreateNamespaceWithCleanup(t *testing.T, ctx context.Context, client ctrlruntimeclient.Client) *corev1.Namespace

CreateNamespaceWithCleanup creates a namespace with a generated name test-<something> and registers a hook on T.Cleanup that removes it at the end of the test.

func PackageChart

func PackageChart(t *testing.T, chartDir string, destDir string) (string, int64)

PackageChart packages the chart in chartDir into a chart archive file (i.e. a tgz) in destDir directory and returns the full path and the size of the archive.

func StartHttpRegistryWithAuthAndCleanup

func StartHttpRegistryWithAuthAndCleanup(t *testing.T, glob string) string

StartHttpRegistryWithAuthAndCleanup starts a Helm http registry with basic auth enabled and uploads charts archives matching glob and returns the registry URL. the basic auth is hardcoded to Username: "username", Password: "password".

func StartHttpRegistryWithCleanup

func StartHttpRegistryWithCleanup(t *testing.T, glob string) string

StartHttpRegistryWithCleanup starts a Helm http registry and uploads charts archives matching glob and returns the registry URL.

func StartOciRegistry

func StartOciRegistry(t *testing.T, glob string) string

StartOciRegistry start an oci registry and uploads charts archives matching glob and returns the registry URL.

func StartOciRegistryWithAuth

func StartOciRegistryWithAuth(t *testing.T, glob string) (string, string)

StartOciRegistryWithAuth start an oci registry with authentication, uploads charts archives matching glob, returns the registry URL and registryConfigFile. registryConfigFile contains the credentials of the registry.

func StartTestEnvWithCleanup

func StartTestEnvWithCleanup(t *testing.T, crdPath string) (context.Context, ctrlruntimeclient.Client, string)

StartTestEnvWithCleanup bootstraps the testing environment and return the to the kubeconfig. It also registers a hook on T.Cleanup to stop the env and remove the kubeconfig.

Types

type ReleaseStorageInfo

type ReleaseStorageInfo struct {
	// Name of the secret containing release information.
	Name string

	// Version of the release.
	Version string
}

ReleaseStorageInfo holds information about the secret storing the Helm release information.

func MapToReleaseStorageInfo

func MapToReleaseStorageInfo(secrets []corev1.Secret) []ReleaseStorageInfo

MapToReleaseStorageInfo maps the secrets containing the Helm release information to a smaller struct only containing the Name of the secret and the release version.
