+Feature: Test creating an AIText question
+              As a teacher
+              In order to test my students
+              I need to be able to create an aitext question
+
+        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 config values are set as admin:
+                  | model | gpt-4,gpt-4o | tool_aiconnect |
+        @javascript
+        Scenario: Create an AI text question with Response format set to 'HTML editor'
+             When I am on the "Course 1" "core_question > course question bank" page logged in as teacher
+    # id_sampleanswer because it is collapsed when the form is opened for editing.
+              And I add a "AI Text" question filling the form with:
+                  | Question name    | aitext-001                      |
+                  | Question text    | Write an aitext with 500 words. |
+                  | General feedback | This is general feedback        |
+                  | Response format  | HTML editor                     |
+                  | AI Prompt        | Evaluate this                   |
+                  | Mark scheme      | Give one mark if correct        |
+
+             Then I should see "aitext-001"
+
+        Scenario: Create an AI Text question with Response format set to 'HTML editor with the file picker'
+             When I am on the "Course 1" "core_question > course question bank" page logged in as teacher
+              And I add a "AI Text" question filling the form with:
+                  | Question name    | aitext-002                      |
+                  | Question text    | Write an aitext with 500 words. |
+                  | General feedback | This is general feedback        |

+                  | Mark scheme      | Give one mark if correct        |
+                  | id_sampleanswer  | sample  answer                  |
+                  | Model            | gpt-4                           |
+
+
+
+             Then I should see "aitext-002"
+        @javascript
+        Scenario: Create an AI Text question for testing some default options
+             When I am on the "Course 1" "core_question > course question bank" page logged in as teacher
+              And I add a "AI Text" question filling the form with:
+                  | Question name         | aitext-003                      |
+                  | Question text         | Write an aitext with 500 words. |
+                  | General feedback      | This is general feedback        |

+
+
+             Then I should see "aitext-003"
+    # Checking that the next new question form displays user preferences settings.
+              And I press "Create a new question ..."
+              And I set the field "item_qtype_aitext" to "1"
+              And I click on "Add" "button" in the "Choose a question type to add" "dialogue"
+              And the following fields match these values:
+                  | id_responsefieldlines | 15 |
