Fix Appium tests with iOS

[deadlyfingers]

Creating Appium POC project with JXcore to test with Cordova 6

[deadlyfingers]

Seems to better error reporting using beta version of Appium: npm install -g [email protected]
But looks like instruments can't communicate with device...
Also got error with Android device with Appium beta:
FATAL ERROR: invalid table size Allocation failed - process out of memory

In POC Cordova app I get error in test for 'POST /session/:sessionID/execute_async' command on iOS simulator: Original error: Error: SecurityError: DOM Exception 18

On iOS device appium error: Instruments exited with code 255
Instruments Usage Error : Specified target process is invalid: org.thaliproject.postcardapp

Need to modify tests that involve page changing with new Appium web driver - it now fails when the new page loads

Error: [waitForConditionInBrowser("document.querySelectorAll('div').length > 0",36000)] Error response status: 17, , JavaScriptError - An error occurred while executing user supplied JavaScript. Selenium error: javascript error: document unloaded while waiting for result
  (Session info: chrome=47.0.2526.100)
  (Driver info: chromedriver=2.20.353124 (035346203162d32c80f1dce587c8154a1efa0c3b),platform=Mac OS X 10.10.5 x86_64)

• so 'waitForConditionInBrowser' doesn't wait for a condition in the browser to evaluate true anymore!!

Notes on fixing iOS tests broken after updating Cordova 6 / Appium 1.5 beta:

• replacing 'safeEval' with 'eval' - tests with 'safeEval' commands will fail.
• make sure 'waitForElementByCss' after changing page with 'click()'
• don't use 'waitForConditionInBrowser' to wait for browser conditions!

I now have all tests working again on iOS simulator!

There are Appium / instruments issues with iOS devices that can't be fixed here so I think we can close the issue.

Otherwise I have tried the standard iOS Webkit Debug Proxy, and the Appium recommend fork -
