Client returns the current Kubernetes client for the test harness.

func (*Harness) Config

func (h *Harness) Config() (*rest.Config, error)

Config returns the current Kubernetes configuration - either from the environment or from the created temporary control plane.

func (*Harness) DiscoveryClient

func (h *Harness) DiscoveryClient() (discovery.DiscoveryInterface, error)

DiscoveryClient returns the current Kubernetes discovery client for the test harness.

func (*Harness) DisplayFailedTest

func (h *Harness) DisplayFailedTest()

func (*Harness) DockerClient

func (h *Harness) DockerClient() (testutils.DockerClient, error)

DockerClient returns the Docker client to use for the test harness.

func (*Harness) GetLogger

func (h *Harness) GetLogger() testutils.Logger

GetLogger returns an initialized test logger.

func (*Harness) GetTimeout

func (h *Harness) GetTimeout() int

GetTimeout returns the configured timeout for the test suite.

func (*Harness) LoadTests

func (h *Harness) LoadTests(dir string, shouldSkip func(string) bool) ([]*Case, error)

LoadTests loads all of the tests in a given directory.

func (*Harness) Report

func (h *Harness) Report()

Report defines the report phase of the kuttl tests. If report format is nil it is skipped. otherwise it will provide a json or xml format report of tests in a junit format.

func (*Harness) Run

func (h *Harness) Run()

Run the test harness - start the control plane and then run the tests.

func (*Harness) RunKIND

func (h *Harness) RunKIND() (*rest.Config, error)

RunKIND starts a KIND cluster.

func (*Harness) RunTestEnv

func (h *Harness) RunTestEnv() (*rest.Config, error)

RunTestEnv starts a Kubernetes API server and etcd server for use in the tests and returns the Kubernetes configuration.

func (*Harness) RunTests

func (h *Harness) RunTests()

RunTests should be called from within a Go test (t) and launches all of the KUTTL integration tests at dir.

func (*Harness) Setup

func (h *Harness) Setup()

Setup spins up the test env based on configuration It can be used to start env which can than be modified prior to running tests, otherwise use Run().

func (*Harness) Stop

func (h *Harness) Stop()

type Step

type Step struct {
	Name       string

LoadYAML loads the resources from a YAML file for a test step:

  • If the YAML file is called "assert", then it contains objects to add to the test step's list of assertions.
  • If the YAML file is called "errors", then it contains objects that, if seen, mark a test immediately failed.
  • All other YAML files are considered resources to create.
