+Feature: List Books using Vue.js UI
+
+  Scenario: Launch cds server for bookshop
+    When we run the 'bookshop' server
+    And wait for 1s
+    Then it should listen at 'http://localhost:4004'
+
+  Scenario: Display Books List
+    When we open page '/vue/index.html'
+    And wait for 1s
+    Then it should list these rows in table 'books':
+      | Wuthering Heights | Emily Brontë      |
+      | Jane Eyre         | Charlotte Brontë  |
+      | The Raven         | Edgar Allen Poe   |
+      | Eleonora          | Edgar Allen Poe   |
+      | Catweazle         | Richard Carpenter |
+
+  Scenario: Select a Book
+    When we click on the 1st row in table 'books'
+    Then it shows '12' in 'stock'
+
+  Scenario: Order One Book
+    When we click on button 'Order:'
+    Then it succeeds with 'ordered 1 item(s)'
+
+  Scenario: Order Four Books
+    When we enter '4' into 'amount'
+    And we click on button 'Order:'
+    Then it succeeds with 'ordered 4 item(s)'
+
+  Scenario: Order Amount Exceeding Stock
+    When we enter '9' into 'amount'
+    And we click on button 'Order:'
+    Then it fails with '9 exceeds stock'
