Feature: Test editing a Numerical question
  As a teacher
  In order to be able to update my Numerical question
  I need to edit them

  Background:
    Given the following "users" exist:
      | username |
      | teacher  |
    And the following "courses" exist:
      | fullname | shortname | category |
      | Course 1 | C1        | 0        |
    And the following "course enrolments" exist:
      | user    | course | role           |
      | teacher | C1     | editingteacher |
    And the following "question categories" exist:
      | contextlevel | reference | name           |
      | Course       | C1        | Test questions |
    And the following "questions" exist:
      | questioncategory | qtype     | name                  | template |
      | Test questions   | numerical | Numerical for editing | pi       |

  Scenario: Edit a Numerical question when using a custom decimal separator
    Given the following "language customisations" exist:
      | component       | stringid | value |
      | core_langconfig | decsep   | #     |
    When I am on the "Numerical for editing" "core_question > edit" page logged in as teacher
    And the field "id_answer_0" matches value "3#14"
    And I set the following fields to these values:
      | Question name | |
    And I press "id_submitbutton"
    And I should see "You must supply a value here."
    And I set the following fields to these values:
      | Question name | Edited Numerical name |
    And I press "id_submitbutton"
    Then I should see "Edited Numerical name"
    And I choose "Edit question" action for "Edited Numerical name" in the question bank
    And I set the following fields to these values:
      | id_answer_1    | 3#141592 |
      | id_tolerance_1 | 0#005    |
      | id_answer_2    | 3.05     |
      | id_tolerance_2 | 0.005    |
      | id_answer_3    | 3,01     |
    And I press "id_submitbutton"
    And I should see "Edited Numerical name"

  Scenario: Edit a Numerical question with very small answer
    When I am on the "Numerical for editing" "core_question > edit" page logged in as teacher
    And I set the following fields to these values:
      | id_answer_0    | 0.00000123456789 |
      | id_tolerance_1 | 0.0000123456789  |
    And I press "id_submitbutton"
    And I choose "Edit question" action for "Numerical for editing" in the question bank
    Then the following fields match these values:
      | id_answer_0    | 0.00000123456789 |
      | id_tolerance_1 | 0.0000123456789  |

  Scenario: Edit a Numerical question with optional units
    Given I am on the "Numerical for editing" "core_question > edit" page logged in as teacher
    # Edit the existing numerical question, changing the unit to optional.
    And I set the following fields to these values:
      | Question name    | Numerical Question (optional)              |
      | Question text    | How many meter is 1m + 20cm + 50mm?        |
      | Default mark     | 1                                          |
      | General feedback | The correct answer is 1.25m                |
      | id_answer_0      | 1.25                                       |
      | id_tolerance_0   | 0                                          |
      | id_fraction_0    | 100%                                       |
      | id_answer_1      | 125                                        |
      | id_tolerance_1   | 0                                          |
      | id_fraction_1    | 0%                                         |
      | id_unitrole      | Units are optional.                        |
      | id_unitsleft     | on the right, for example 1.00cm or 1.00km |
      | id_unit_0        | m                                          |
    And I press "submitbutton"
    When I choose "Edit question" action for "Numerical Question (optional)" in the question bank
    # Confirm that the numerical question with optional unit is updated accordingly.
    Then the following fields match these values:
      | Question name    | Numerical Question (optional)                                                                          |
      | Question text    | How many meter is 1m + 20cm + 50mm?                                                                    |
      | Default mark     | 1                                                                                                      |
      | General feedback | The correct answer is 1.25m                                                                            |
      | id_unitrole      | Units are optional. If a unit is entered, it is used to convert the response to Unit 1 before grading. |
      | id_unitsleft     | on the right, for example 1.00cm or 1.00km                                                             |
      | id_unit_0        | m                                                                                                      |
