Assume you have been asked to use the Equivalence Partitioning method to check the ATM machine login function regarding PIN number validation. Here are some detailed requirements:

Users must use a valid ATM card and enter the 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 char from the following list:
  • ?, #,@
• The length of each valid PIN must be in the range of 6 to 10.

Whenever an invalid PIN is entered, one of the 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.

1. Please list your identified equivalence classes when you testing this function, and present them using a table (or a diagram). (12%)
2. Based on these equivalence classes identify and present test cases in a table. (13%)
