Types

type CadvisorActions

type CadvisorActions interface {
	// Returns a cAdvisor client to the machine being tested.
	Client() *client.Client
}

type DockerActions

type DockerActions interface {
	// Run the no-op pause Docker container and return its ID.
	RunPause() string

	// Run the specified command in a Docker busybox container and return its ID.
	RunBusybox(cmd ...string) string

	// Runs a Docker container in the background. Uses the specified DockerRunArgs and command.
	// Returns the ID of the new container.
	//
	// e.g.:
	// Run(DockerRunArgs{Image: "busybox"}, "ping", "www.google.com")
	//   -> docker run busybox ping www.google.com
	Run(args DockerRunArgs, cmd ...string) string
}

type DockerRunArgs

type DockerRunArgs struct {
	// Image to use.
	Image string

	// Arguments to the Docker CLI.
	Args []string
}

type Framework

type Framework interface {
	// Clean the framework state.
	Cleanup()

	// The testing.T used by the framework and the current test.
	T() *testing.T

	// Returns information about the host being tested.
	Host() HostInfo

	// Returns the Docker actions for the test framework.
	Docker() DockerActions

	// Returns the cAdvisor actions for the test framework.
	Cadvisor() CadvisorActions
}

Integration test framework.

func New

func New(t *testing.T) Framework

Instantiates a Framework. Cleanup *must* be called. Class is thread-compatible. All framework actions report fatal errors on the t specified at creation time.

Typical use:

func TestFoo(t *testing.T) {
	fm := framework.New(t)
	defer fm.Cleanup()
     ... actual test ...
}

type HostInfo

type HostInfo struct {
	Host            string
	Port            int
	GceInstanceName string
}

func (HostInfo) FullHost

func (self HostInfo) FullHost() string

Returns: http://<host>:<port>/
