Possible Earl Grey actions we would want to expose?

[LeoNatan]

Earl Grey has many actions which we don't yet support in Detox.

One such action, as discussed in #139, is for handling picker views.

We may want to add individual support or use invoke to create a general way of using these actions without explicit support in JS. Such a solution must have good user-facing API.

I raised the subject of pickers in #139. I guess the naive implementation is something like:

class SetPickerColumnAction extends Action {
  constructor(value) {
    super();
    if (typeof value !== 'string') throw new Error(`SetPickerColumnAction ctor argument must be a string, got ${typeof value}`);
    this._call = invoke.call(invoke.IOS.Class('GREYActions'), 'actionForSetPickerColumn:', value);
  }
}

As @LeoNatan said in #139:

However, this is a very naive approach, as picker views can have custom views.

Questions, then:

1. Is it still useful to implement something like this, since it would be useful now?
2. What would a less naive version look like? How would Earl Grey handle a picker with custom views?

There's a WIP PR by @DanielMSchmidt which generates JS invocations according to objC header files.
#178

The first milestone is to wrap GREYActions. We will merge it soon.
