code: func (t *ActivatedTask) WalkShouldReturn(request interface{}, expect ...interface{}) string {

docs: // WalkShouldReturn is a shorthand for the package-level WalkShouldReturn which
  // binds the activated auth to the WalkGraph request, but otherwise behaves
  // identically.
  //
  // Use this method like:
  //   req := &dm.WalkGraphReq{...}
  //   So(req, activated.WalkShouldReturn, &dm.GraphData{
  //     ...
  //   })
