	Stderr     io.Writer
}

type Harness

type Harness interface {
	Create(context.Context) error
	Destroy(context.Context) error

}

type RunError

type RunError struct {

func (*RunError) Error

func (e *RunError) Error() string

type Stack

}

Stack is a lifo queue used to easily manage resources that need to be torn down by harnesses. It is a LIFO queue, so the first item added is the last item torn down.

func NewStack

func NewStack() *Stack

func (*Stack) Add

func (r *Stack) Add(f func(ctx context.Context) error) error

func (*Stack) Teardown

func (r *Stack) Teardown(ctx context.Context) error
