Potentially create abstraction for testingOutput sender arguments

I'm seeing these three values grouped together often like this:

testingOutput.push({action: action, target: target, options: options });

Curious if we should make an abstraction of this object and give it a name.

Maybe we could do something like this.

function buildCapybaraAction(action, data = nil) {
  switch(action) {
    case 'fill_in':
      // ...
    case 'click_on':
      // ...
  }

  return {action: action, target: target, options: options}
}

Here data represents whatever information is necessary to build the arguments and options for the action we want to build.

I still haven't sifted through the code enough to know if this is a viable option, but I think it will make the intention of the code clearer to first-time readers, and we can perhaps simplify the current code.
