Topic #: 8
A system sets new users' password to a temporary password
The temporary password is a random number based on the first sft: characters of the username.
If the username is shorter than 6 characters, the system displays an error message.
Which of the following is a possible representation of equivalence classes for the username string?
The equivalence classes for the username string are based on the length of the string, not on the type of password or the error message. Therefore, option C is correct, as it divides the username string into two equivalence classes: shorter than 6 characters and equal to or longer than 6 characters. Option A is incorrect, as it does not consider the length of the username string. Option B is incorrect, as it does not specify the criteria for displaying or not displaying the error message. Option D is incorrect, as it confuses the username string with the password string.
