ErrorTester don't work with Behat Exception

[pocky]

error_get_last() return NULL for Behat Exception so exemplify can't work. Could you confirm this?

Feature: Test project

  Scenario:                               # features/beer.feature:3
    Given I am a customer                 # FeatureContext::iAmACustomer()
    When I want a beer                    # FeatureContext::iWantABeer()
    Then the bartender should give me one # FeatureContext::theBartenderShouldGiveOne()
    And I say thanks "Tom"                # FeatureContext::iSayThanks()
      Fatal error: Call to undefined method Customer::thanks() (Behat\Testwork\Call\Exception\FatalThrowableError)
    And I drink my beer                   # FeatureContext::iDrinkMyBeer()
    And I am "drunk"                      # FeatureContext::iAm()

I don't know how to handle the exception, I tried with events and try/catch on setUp but this is (apparently) not the solution.

this is totally expected, because error_get_last does not deal with exceptions at all in PHP, but only with errors (warnings, notices, etc...)

Got It! PR incoming!

@pocky Any luck with the PR? If it's not PR-ready, could you at least make a gist of the modification needed to get it to work?

[richardmiller-zz]

Is this with the exceptions and handlers introduced in behat 3.2? If so I think they should remove the need for this extension altogether if they are used instead of this extension's error observers.

@RemiWoler The problem is the gap between current version (phpspec 2, multi-repository) and my working one (phpspec3, monorep, many PR on extensions). I didn't take time to apply/tests changes on 0.3.0 with Behat 2/3 and phpspec 2 (I tried quickly and it was not good).

Working version for behat 3/phpspec 3 is here pocky/BehatSpec@f72ea6a
