Multiple choice technology testing

An input field takes the data between 1000 and 2000. The boundary values for testing this field are:

  1. 1000,1001,2000,2001

  2. 999,1000,2000,2001

  3. 1000,2000

  4. 1000,1500,2000

B Correct answer
Explanation

Boundary value analysis tests at the edges of valid input ranges. For 1000-2000, test just below the lower bound (999), at the lower bound (1000), at the upper bound (2000), and just above the upper bound (2001). This catches off-by-one errors. Option B captures all four critical boundary values.
