ISQI Certified Tester Foundation Level — Question 86

An input field takes the year of birth between 1900 and 2004. The boundary values for testing this field are:

Answer options

• A. 0,1900,2004,2005
• B. 1900, 2004
• C. 1899,1900,2004,2005
• D. 1899, 1900, 1901,2003,2004,2005

Correct answer: C

Explanation

The correct answer is C because it includes the values just below and above the valid range, specifically 1899 and 2005, as well as the valid boundaries 1900 and 2004. Options A and D include values that are outside the specified range but do not provide the necessary boundary tests, while B only includes the valid boundaries without the out-of-bounds values.
