Variable Dimension Equivalence classes Numeric Length All values field having lengths in the range of Min-allowedlength to Maxallowed-length Type of Characters All values having lengths outside the allowed range All values containing allowed characters. 0-9 for integer and floatingpoint values, and an additional decimal point for floating-point values. All values containing at least one character that is NOT allowed. Test cases (Best representatives) A value having: 1) Min-allowed-length 2) Max-allowed-length These two are at the function level. A value having: 1) Min-allowed-length -1 2) Max-allowed-length + 1 3) Zero length (if this is other than the min-allowed or minallowed-1) 4) Max-length allowed by the system, if different from that of the function 5) Max-length allowed by the system + 1, if different from that of the function. For integer and floating-point values: 1) Value having 0 as one of the digits 2) Value having 9 as one of the digits For only floating-point values: 3) Value having one decimal point at right place For integer and floating-point values: 1) Value having the character corresponding to one ASCII code just beneath the ASCII for 0. 2) Value having the character corresponding to ASCII code just beyond the ASCII for 9. For only floating-point values: 3) Value having more than one decimal point 4) Value having a character corresponding to ASCII code just beneath the decimal point. 5) Value having a character corresponding to ASCII code just beyond the decimal point. Risks 1) Failure to process numeric values correctly, that have their lengths within the allowed range. 2) Mishandling of lower and upper boundary values. 1) Mishandling of numeric values that have their lengths outside the allowed range. 2) Mishandling of values just beneath and beyond the lower and upper boundaries respectively. 3) Mishandling of too small, too long strings and beyond, at the system level. 1) Failure to process numeric values correctly, that have digits 0-9 and one decimal point for floatingpoint values. 2) Mishandling of lower and upper boundary values. 1) Mishandling of values that have non-digits 2) Mishandling of values having more than one decimal point, in case of a floating-point field. 3) Mishandling of lower and upper and boundary values.
Variable Dimension Equivalence classes Numeric field Size All values within the size range of minallowed-value to maxallowed-value All values having sizes outside the allowed range Test cases (Best representatives) 1) Min-allowed-value 2) Max-allowed-value These two are at the function level. 1) Min-allowed-value -1 2) Max-allowed-value + 1 3) Null 4) Minimum possible number allowed to be entered in the field at the system level 5) Maximum possible number allowed to be entered in the field at the system level 6) Min-possible number - 1 at the system level. 7) Max-possible number + 1 at the system level Risks 1) Failure to process numeric values correctly that are within the allowed range of sizes 2) Mishandling of lower and upper boundary values. 1) Mishandling of numeric values that are outside the allowed range of size 2) Mishandling of values just beneath and beyond the lower and upper boundaries respectively. 3) Mishandling of values that are too small and too big at the system level and even beyond.
