Types

type ExpectProcess

type ExpectProcess struct {

	// StopSignal is the signal Stop sends to the process; defaults to SIGKILL.
	StopSignal os.Signal
	// contains filtered or unexported fields
}

func NewExpect

func NewExpect(name string, arg ...string) (ep *ExpectProcess, err error)

NewExpect creates a new process for expect testing.

func NewExpectWithEnv

func NewExpectWithEnv(name string, args []string, env []string) (ep *ExpectProcess, err error)

NewExpectWithEnv creates a new process with user defined env variables for expect testing.

func (*ExpectProcess) Close

func (ep *ExpectProcess) Close() error

Close waits for the expect process to exit. Close currently does not return error if process exited with !=0 status. TODO: Close should expose underlying proces failure by default.

func (*ExpectProcess) Expect

func (ep *ExpectProcess) Expect(s string) (string, error)

Expect returns the first line containing the given string.

func (*ExpectProcess) ExpectFunc

func (ep *ExpectProcess) ExpectFunc(f func(string) bool) (string, error)

ExpectFunc returns the first line satisfying the function f.

func (*ExpectProcess) LineCount

func (ep *ExpectProcess) LineCount() int

LineCount returns the number of recorded lines since the beginning of the process.

func (*ExpectProcess) Lines

func (ep *ExpectProcess) Lines() []string

func (*ExpectProcess) ProcessError

func (ep *ExpectProcess) ProcessError() error

func (*ExpectProcess) Send

func (ep *ExpectProcess) Send(command string) error

func (*ExpectProcess) Signal

func (ep *ExpectProcess) Signal(sig os.Signal) error

Signal sends a signal to the expect process

func (*ExpectProcess) Stop

func (ep *ExpectProcess) Stop() error

Stop kills the expect process and waits for it to exit.

func (*ExpectProcess) Wait

func (ep *ExpectProcess) Wait()

Wait waits for the process to finish.
