Boundary Testing

• A boundary test tries to establish that the
  boundary is in the correct spot.
• Thus, test cases are chosen on the boundary and
  as close as possible on the open side.
• 2-on, 1-off means two on the boundary spread
  far apart and one just off the boundary in
  between the other two

• Hours must be greater than zero and less than 80
• Time and a half is paid on hours over 40

Boundaries in the triangle program

• Assume max length is 10
• What would be 2-on, 1-off for the boundary
  between isosceles and not-a-triangle?
