Documentation

Overview

Package exec provides wrapped implementations of os/exec's Command and CommandContext functions that allow for command creation to be overridden, thereby allowing commands to be mocked.

Functions

func Command

func Command(name string, arg ...string) *goexec.Cmd

Command wraps os/exec.Command, and implements the same behaviour.

func CommandContext

func CommandContext(ctx context.Context, name string, arg ...string) *goexec.Cmd

CommandContext wraps os/exec.CommandContext, and implements the same behaviour.

Types

type CmdCreator

type CmdCreator func(context.Context, string, ...string) *goexec.Cmd

CmdCreator instances are used to create commands. os/exec.CommandContext is a valid CmdCreator.

type CmdCreatorMiddleware

type CmdCreatorMiddleware struct {
	// contains filtered or unexported fields
}

CmdCreatorMiddleware creates *exec.Cmd instances that delegate command creation to a provided callback.

func NewMiddleware

func NewMiddleware(mock func(context.Context, CmdCreator, string, ...string) *goexec.Cmd) CmdCreatorMiddleware

NewMiddleware adds a middleware to the command creation stack.

func (CmdCreatorMiddleware) Remove

func (mc CmdCreatorMiddleware) Remove()

Remove removes the command creation middleware from the stack.
