0.12.* - Timeout when typing char that does not exist

[jmoody]

Motivation

• uia_type_string enters loop when trying to type a key that does not exist on the keyboard - UITextFields only uia_type_string enters loop when trying to type a key that does not exist on the keyboard - UITextFields only #310
• keyboard_enter_text into field with UIKeyboardTypeDecimalPad does not finish keyboard_enter_text into field with UIKeyboardTypeDecimalPad does not finish #555

This PR addresses #310 and #555 by adding a timeout to uia_type_string; cannot type more than 10 seconds. I added a options :timeout argument to keyboard_enter_text to allow users who need to type exceptionally long pieces of text.

This is 0.12.0 release because it changes keyboard_enter_text public API.

I also added some tests to get a better understanding of these two issues.

• Typing backslashes on iOS 8 iPad undocks the keyboard. Regression on uia_type_string should properly escape the 'backslash' character #284 Typing backslashes on iOS 8 iPad undocks the keyboard. Regression on #284 #574
• Typing backslashes on iOS 8 iPad keyboard inserts "." instead of "". Regression on uia_type_string should properly escape the 'backslash' character #284 Typing backslashes on iOS 8 iPad keyboard inserts "." instead of "\". Regression on #284 #575
• @michaelkirk Can you review?
• @krukow This introduces a timeout exception to uia_type_string. Is the 10 second default too short?

@jmoody I appreciate the effort and initiative to fix this problem, but please don't merge this pull request. It is solving the problem in the wrong place. I would like some time to fix the true cause.

These are the Scenarios [1] that are hanging indefinitely; they never finish.

They were passing until ~ Nov 5th @ or around the 0.11.4 release or one of the pre-releases.

@keyboard
Feature:  keyboard_enter_text should fail if key does not exist
  In order to catch up on my beauty sleep
  As a calabash developer
  I want uia_type_string to start behaving itself.

  Background: get me to the text tab
    Given I am looking at the Text tab

  Scenario: try type a key that does not exist on text field keyboard
    And one of the text fields has the default keyboard showing
    When I type a key that does not exist it should raise an exception


  Scenario: try type a key that does not exist on text view keyboard
    And one of the text views has the default keyboard showing
    When I type a key that does not exist it should raise an exception

@krukow
Do you think the timeout on uia_type_string has merit by itself? Regardless of whether you can make a fix at a lower level?

Thanks for the effort and research.

We won't merge this pull request since we can fix the root cause instead (which was a bug in CalabashScript). Fixed with krukow/calabash-script@d7a7f2c

Should be fixed in 0.11.5.pre3 - #630

Please reopen if you see fit.
