Functions

func ExecTask added in v1.0.0 

func ExecTask(t *testing.T, driver *DriverHarness, taskID string, cmd string, tty bool, stdin string) (exitCode int, stdout, stderr string)

func ExecTaskStreamingConformanceTests added in v0.9.2 

func ExecTaskStreamingConformanceTests(t *testing.T, driver *DriverHarness, taskID string)

func SetEnvvars 

func SetEnvvars(envBuilder *taskenv.Builder, fsi drivers.FSIsolation, taskDir *allocdir.TaskDir, conf *config.Config)

SetEnvvars sets path and host env vars depending on the FS isolation used.

func TestExecFSIsolation added in v0.9.2 

func TestExecFSIsolation(t *testing.T, driver *DriverHarness, taskID string)

TestExecFSIsolation asserts that exec occurs inside chroot/isolation environment rather than on host

func TestExecTaskStreamingBasicResponses added in v0.9.2 

func TestExecTaskStreamingBasicResponses(t *testing.T, driver *DriverHarness, taskID string)

func TestTaskDNSConfig added in v0.12.0 

func TestTaskDNSConfig(t *testing.T, driver *DriverHarness, taskID string, dns *drivers.DNSConfig)

TestTaskDNSConfig asserts that a task is running with the given DNSConfig

Types

type DriverHarness 

type DriverHarness struct {
	drivers.DriverPlugin
	// contains filtered or unexported fields
}

func NewDriverHarness 

func NewDriverHarness(t testing.T, d drivers.DriverPlugin) *DriverHarness

func (*DriverHarness) Impl 

func (d *DriverHarness) Impl() drivers.DriverPlugin

func (*DriverHarness) Kill 

func (h *DriverHarness) Kill()

func (*DriverHarness) MkAllocDir 

func (h *DriverHarness) MkAllocDir(t *drivers.TaskConfig, enableLogs bool) func()

MkAllocDir creates a temporary directory and allocdir structure. If enableLogs is set to true a logmon instance will be started to write logs to the LogDir of the task A cleanup func is returned and should be deferred so as to not leak dirs between tests.

func (*DriverHarness) WaitUntilStarted 

func (h *DriverHarness) WaitUntilStarted(taskID string, timeout time.Duration) error

WaitUntilStarted will block until the task for the given ID is in the running state or the timeout is reached

type MockDriver 

type MockDriver struct {
	base.MockPlugin
	TaskConfigSchemaF  func() (*hclspec.Spec, error)
	FingerprintF       func(context.Context) (<-chan *drivers.Fingerprint, error)
	CapabilitiesF      func() (*drivers.Capabilities, error)
	RecoverTaskF       func(*drivers.TaskHandle) error
	StartTaskF         func(*drivers.TaskConfig) (*drivers.TaskHandle, *drivers.DriverNetwork, error)
	WaitTaskF          func(context.Context, string) (<-chan *drivers.ExitResult, error)
	StopTaskF          func(string, time.Duration, string) error
	DestroyTaskF       func(string, bool) error
	InspectTaskF       func(string) (*drivers.TaskStatus, error)
	TaskStatsF         func(context.Context, string, time.Duration) (<-chan *drivers.TaskResourceUsage, error)
	TaskEventsF        func(context.Context) (<-chan *drivers.TaskEvent, error)
	SignalTaskF        func(string, string) error
	ExecTaskF          func(string, []string, time.Duration) (*drivers.ExecTaskResult, error)
	ExecTaskStreamingF func(context.Context, string, *drivers.ExecOptions) (*drivers.ExitResult, error)
	MockNetworkManager
}

MockDriver is used for testing. Each function can be set as a closure to make assertions about how data is passed through the base plugin layer.
