NullPointerException parsing a Background section that has a Before hook.

XMLWordPrintable

      As of Cucumber 2.0.1 (cucumber-core 1.2.0), the JSON output format has changed. It now adds a before array into the Background element. That causes GherkinCallback.java to crash because it assumes before will only exist for a Scenario:

      ERROR: Build step failed with exception

      Example feature:

      Feature:

    Background:
        Given I am in the app

    Scenario:
        When I do something
        Then I should see something

      Example hooks:

      Before do |scenario|
    # Do something.
end

      Produces a JSON output similar to:

      [{
  uri: "features/background_before.feature",
  line: 1,
  ...
  elements: [
    {keyword: "Background",
    ...
     before: []
     steps: []
    }
  ]
}]

      When locking cucumber to version 2.0.0, and all else remaining the same, the old JSON format is produced:

      [{
  uri: "features/background_before.feature,
  ...
  elements: [
    {
      keyword: "Background",
      steps: []
    },
    {
      keyword: "Scenario",
      steps: []
    }
  ]
}]

      Note that it does not even have the before array at all.
