+            This test requires mouse with a scrolling wheel or
+            device that is able to simulate scrolling using gestures.
+            If you do not have such device press "Pass" to skip testing.
+            You should see a ScrollPane with some labels in it and two checkboxes.
+            For each of the four combinations of the two checkboxes,
+            move the cursor over the ScrollPane and rotate the mouse wheel.
+            When (and ONLY when) the 'WheelListener added' checkbox is checked,
+            scrolling the mouse wheel should produce a text message in the log area.
+            When (and ONLY when) the 'Wheel scrolling enabled' checkbox is checked,
+            the ScrollPane should scroll when mouse wheel is scrolled on top of it.
+            If all four checkbox combinations work properly press "Pass",
+            otherwise press "Fail".
