Question #$2$: Equivalence Partitioning Testing Questions. $(20\%)$

Assume you have been asked to use Equivalence Partitioning method to check the ATM machine

login function regarding to PIN number validation. Here are some detailed requirements:

Users must use valid ATM card and enter a correct PIN number to access their accounts. Otherwise, a

rejection message will be displayed to them.

Here are some specification descriptions relating to a valid PIN number.

$$ Each valid PIN number must be formed with letters $($a$$ to $$z$)$ and digitals

$$ Each PIN must include at least one up$-$case letter

$$ Each PIN is acceptable if it includes one special chars from the following list:

o $\%,$ #$,$@

$$ The length of each valid PIN must be in the range from $8$ to $15.$

Whenever an invalid PIN is entered, one of following messages will be displayed:

$$Incorrect Password$-$ This suggests that a PIN $($entered by a user$)$ is valid but not correct.

$$Invalidated Password$-$ This suggests that a PIN $($entered by a user$)$ is invalid.

a$)$ Please list your identified equivalence classes when you testing this function, and present them using a

table $($or a diagram$).(12\%)$

b$)$ Based on these equivalence classes identify and present test cases in a table. $(13\%)$
