Feature: Add an adaptive quiz
  In order to evaluate students using an adaptive questions strategy
  As a teacher
  I need to add an adaptive quiz activity to a course

  Background:
    Given the following "users" exist:
      | username | firstname | lastname    | email                       |
      | teacher1 | John      | The Teacher | johntheteacher@example.com  |
      | student1 | Peter     | The Student | peterthestudent@example.com |
    And the following "courses" exist:
      | fullname | shortname | category |
      | Course 1 | C1        | 0        |
    And the following "course enrolments" exist:
      | user     | course | role           |
      | teacher1 | C1     | editingteacher |
      | student1 | C1     | student        |
    And the following "question categories" exist:

      | Adaptive Quiz Questions | truefalse | TF3  | Third question.  |

  @javascript
  Scenario: Add an adaptive quiz to a course to be visible to a student
    When the following "core_question > Tags" exist:
      | question | tag    |
      | TF1      | adpq_1 |
    And I log in as "teacher1"
    And I add a "adaptivequiz" activity to course "Course 1" section "1" and I fill the form with:
      | Name                         | Adaptive Quiz               |
      | Description                  | Adaptive quiz description.  |
      | Question pool                | Adaptive Quiz Questions (4) |
      | Starting level of difficulty | 1                           |
      | Lowest level of difficulty   | 1                           |
      | Highest level of difficulty  | 2                           |
      | Minimum number of questions  | 1                           |
      | Maximum number of questions  | 2                           |
      | Standard Error to stop       | 25                          |
      | ID number                    | adaptivequiz1               |
    And I log out
    And I am on the "adaptivequiz1" "Activity" page logged in as "student1"
    Then "Start attempt" "link" should exist

  @javascript
  Scenario: It is impossible to create an adaptive quiz without a properly tagged question for the starting level of difficulty
    When the following "core_question > Tags" exist:
      | question | tag         |
      | TF1      | adpq_001    |
      | TF2      | adpq_2      |
      | TF3      | truefalse_1 |
      | TF3      | TF          |
    And I log in as "teacher1"
    And I add a "adaptivequiz" activity to course "Course 1" section "1" and I fill the form with:
      | Name                         | Adaptive Quiz               |
      | Description                  | Adaptive quiz description.  |
      | Question pool                | Adaptive Quiz Questions (4) |
      | Starting level of difficulty | 1                           |
      | Lowest level of difficulty   | 1                           |
      | Highest level of difficulty  | 2                           |
      | Minimum number of questions  | 1                           |
      | Maximum number of questions  | 2                           |
      | Standard Error to stop       | 25                          |
    Then I should see "The selected questions categories do not contain questions which are properly tagged to match the selected starting level of difficulty."
