If EC=(0, 1) defined on the set of real numbers, then the following values should be tested:

• 0
• 1
• -0.0001 (or some other real value just below 0)
• 1.0001 (or some other real value just above 1)

If the EC is the set of arrays of length 3 containing positive integers, then the following values should be tested:

• [1, 1, 1]
• [maxint, maxint, maxint]

If EC=[0, 1] defined on the set of real numbers, then the following values should be tested:

• 0
• 1
• -0.0001 (or some other real value just below 0)
• 1.0001 (or some other real value just above 1)

If for an input field that accepts only integers the valid EC is defined as the set of values 1 to 9, the following values should be tested:

• 1
• 9
