  @javascript @_file_upload
  Scenario: import a STACK question from a Moodle XML file
    When I am on the "Course 1" "core_question > course question import" page logged in as "teacher"
    And I set the field "id_format_xml" to "1"
    And I upload "question/type/stack/samplequestions/sample_questions.xml" file to "Import" filemanager
    And I press "id_submitbutton"
    Then I should see "Parsing questions from import file."
    And I should see "Importing 7 questions from file"
    And I should see "Give an example of an odd function by typing an expression which represents it."
    And I press "Continue"
    And I should see "test_5_cubic_spline"

    # Now export again.
    And I am on the "Course 1" "core_question > course question export" page
    And I set the field "id_format_xml" to "1"
    And I press "Export questions to file"
    And following "click here" should download between "50000" and "70000" bytes
    # If the download step is the last in the scenario then we can sometimes run
    # into the situation where the download page causes a http redirect but behat
    # has already conducted its reset (generating an error). By putting a logout
    # step we avoid behat doing the reset until we are off that page.
    And I log out
