Deleting arrow

Step 1

• Click on the arrow.

Expected: Arrow should become selected. You can tell the arrow is selected because there are three small square (a.k.a. ‘handles’) at the start, middle and end of the arrow.

• Press ‘delete’.

Expected: The arrow should disappear.

Step 2

• Mouse down on node 'Miles per gallon', and drag the mouse over to node 'Fuel cost' and then mouse up.

Expected: This redraws arrow from 'Miles per gallon' to 'Fuel cost'.

• Mouse down on node 'Miles per gallon', and drag the mouse over to node 'Fuel cost' again

Expected: Arrow is deleted.
