    And I log in as "teacher1"

    And I navigate to "Question bank > Questions" in current page administration
    When I choose "Preview" action for "Test question to be previewed" in the question bank
    And I switch to "questionpreview" window

  Scenario: Question preview shows the question and other information
    Then the state of "What is pi to two d.p.?" question is shown as "Not yet answered"
    And I should see "Marked out of 1.00"
    And I should see "Technical information"
    And I should see "Attempt options"
    And I should see "Display options"

  Scenario: Preview lets the teacher see what happens when an answer is saved
    When I set the field "Answer:" to "1"
    And I press "Save"
    Then the state of "What is pi to two d.p.?" question is shown as "Answer saved"

  Scenario: Preview lets the teacher see what happens when an answer is submitted
    When I set the field "Answer:" to "3.14"
    And I press "Submit and finish"
    Then the state of "What is pi to two d.p.?" question is shown as "Correct"

  Scenario: Preview lets the teacher see what happens with different review options
    Given I set the field "Answer:" to "3.14"
    And I press "Submit and finish"
    When I set the field "Whether correct" to "Not shown"
    And I set the field "Decimal places in grades" to "5"
    And I press "Update display options"

    And I should see "1.00000"

    And I set the field "Answer:" to "3.1"
    And I press "Check"
    Then the state of "What is pi to two d.p.?" question is shown as "Incorrect"
    And I should see "Mark 0.00 out of 3.00"
    And I should see "Not accurate enough."
