Types

type Cmd

type Cmd interface {
	StdinPipe() (io.WriteCloser, error)
	CombinedOutput() ([]byte, error)
	Start() error
	Wait() error
}

Cmd is a facade to exec.Cmd.

type DefaultExecutor

type DefaultExecutor struct{}

DefaultExecutor is a default implementation of Executable that passes back to standard library.

func (DefaultExecutor) Cmd

func (DefaultExecutor) Cmd(cmd string, args []string) Cmd

Cmd implements Executable interface.

func (DefaultExecutor) Exec

func (DefaultExecutor) Exec(cmd string, args []string) ([]byte, error)

Exec implements Executable interface by proxiyng all requests to exec.Command().

type Executable

type Executable interface {
	Exec(cmd string, args []string) ([]byte, error)
	Cmd(cmd string, args []string) Cmd
}

Executable is a facade to exec.Command().Output().

type FakeCmd

type FakeCmd struct{}

FakeCmd implement Cmd interface for testing purposes.

func (FakeCmd) CombinedOutput

func (FakeCmd) CombinedOutput() ([]byte, error)

func (FakeCmd) Start

func (FakeCmd) Start() error

func (FakeCmd) StdinPipe

func (FakeCmd) StdinPipe() (io.WriteCloser, error)

func (FakeCmd) Wait

func (FakeCmd) Wait() error

type FakeExecutor

type FakeExecutor struct {
	Output   []byte
	Error    error
	Commands *string
}

FakeExecutor implements Executable stores faked Output, Error and commands recorded by Exec.

func (*FakeExecutor) Cmd

func (x *FakeExecutor) Cmd(cmd string, args []string) Cmd

func (*FakeExecutor) Exec

func (x *FakeExecutor) Exec(cmd string, args []string) ([]byte, error)

Exec is a method of fake executor that will record all incoming commands and use faked Output and Error.
