+Feature: Filter questions by idnumber
+  As a teacher
+  In order to organise my questions
+  I want to filter the list of questions by idnumber
+
+  Background:
+    Given the following "courses" exist:
+      | fullname | shortname | category |
+      | Course 1 | C1        | 0        |
+    And the following "activities" exist:
+      | activity   | name    | intro              | course | idnumber |
+      | qbank      | Qbank 1 | Question bank 1    | C1     | qbank1   |
+    And the following "question categories" exist:
+      | contextlevel    | reference | name           |
+      | Activity module | qbank1    | Test questions |
+    And the following "questions" exist:
+      | questioncategory | qtype     | name | questiontext               | idnumber |
+      | Test questions   | truefalse | a    | Answer the first question  | q_01_ab  |
+      | Test questions   | numerical | b    | Answer the second question | q_02_bc  |
+      | Test questions   | essay     | c    | Answer the third question  | Q_21_ca  |
+    And I am on the "Qbank 1" "core_question > question bank" page logged in as "admin"
+    And I should see "q_01_ab"
+    And I should see "q_02_bc"
+    And I should see "Q_21_ca"
+
+  Scenario: Filter by a single term
+    When I apply question bank filter "Question ID number" with value "ab"
+    Then I should see "q_01_ab"
+    And I should not see "q_02_bc"
+    And I should not see "Q_21_ca"
+
+  Scenario: Filter by any term
+    When I apply question bank filter "Question ID number" with value "ab, ca"
+    Then I should see "q_01_ab"
+    And I should not see "q_02_bc"
+    And I should see "Q_21_ca"
+
+  Scenario: Filter by all terms
+    When I add question bank filter "Question ID number"
+    And I set the field "Question ID number" to "q, c"
+    And I set the field "Match" in the "Filter 3" "fieldset" to "All"
+    And I press "Apply filters"
+    Then I should not see "q_01_ab"
+    And I should see "q_02_bc"
+    # Filter should be case-insensitive.
+    And I should see "Q_21_ca"
+
+  Scenario: Exclude idnumbers by filter
+    When I add question bank filter "Question ID number"
+    And I set the field "Question ID number" to "ab, ca"
+    And I set the field "Match" in the "Filter 3" "fieldset" to "None"
+    And I press "Apply filters"
+    Then I should not see "q_01_ab"
+    And I should see "q_02_bc"
+    And I should not see "Q_21_ca"
