Calabash can return the type of the visible keyboard

Motivation
Add ability to query keyboard type from a query or first responder.

i.e. keyboard_type("UITextField") => :email

Progress on:

• DeviceAgent needs to detect and interact with Numeric Keyboards DeviceAgent needs to detect and interact with Numeric Keyboards #1160

If you decide that you want keyboard_type to raise on unexpected keyboardType results, I think the error message should be improved.

You can also decide not to raise at all, but just log the exceptional cases and return something like :unknown.

Thanks!!!

Does this need to take an argument?

[jescriba]

We basically just need a query to pass into for :keyboardType - an alternative would be to use the first responder instead. Is that more desired behavior?

[jmoody]

If there is a keyboard visible, then there should be a first responder.

Have you come across a case where we would need a different query?

Should this raise?

In this case a screenshot would not give enough information to help the user or us understand what went wrong.

The way I can see this failing is:

1. keyboardType is nil - either there was no first responder (empty results) or for some reason the first element of the results is nil.
2. keyboardType is "*****" - first responder does not respond to keyboardType.
3. keyboardType is unknown to us - we don't know about it so it is not one of our KEYBOARD_TYPES
4. keyboardType is not a Fixnum ^ similar to above

Point 2 above will happen fairly often - I believe the Slack app, for example, is using a UI Text Input class that does not respond to keyboardType. There is an example of this kind of input field in the CalSmokeApp feature/update-to-0.20.3.

If we do raise, I think we should try to provide as much information as possible (capture why we failed).

Maybe we debug log the exceptional cases and return :unknown if we are on the unhappy path?=

query_result = _query_wrapper(query, :keyboardType).first

keyboard_type = KEYBOARD_TYPES[query_result]

if !keyboard_type
  # Assuming we do not raise
  keyboard_type = :unknown
end
