Discuss ISTQB ATM Exam Topic 2 Question 89

You are the Test Manager for a project to develop a client-server application that allows wine vendors to order custom-assorted packages of wines of several winemakers to sell special packages in their wine shops.

You decide to apply a blended risk-based and reactive testing strategy. Below the exit criteria for the system testing.

EXCR1- Each ''critical'' quality risk item must be covered by at least one test condition EXCR2- Each ''critical'' requirement must be covered by at least one test condition

The following are the ''critical'' requirements of the application:

REQ-SEL-1. The application shall allow the user to order only one package at a time

REQ-SEL-2. The application shall allow the user to select between four different packages (2-bottles, 6-bottles, 12-bottles, 15-bottles)

REQ-SEL-3. The application shall allow the user to order a package containing at least 1 bottle and no more bottles than the package size. No error messages shall be displayed if the user selects a valid number of bottles (at least 1 bottle and no more than the package size)

REQ-SEL-4. The application shall display an error message ''Invalid number of bottles'' if an invalid number of bottles is selected by the user (zero bottles or a number higher than the package size)

REQ-PAY-1. The application shall allow the user to pay with the three accepted credit cards (Visa,

MasterCard, American Express)

REQ-PAY-2. The application shall display an error message ''Invalid credit card'' if invalid credit card data are given by the user

The following is the unique ''critical'' quality risk item that has been identified:

CR-RSK-1. The GUI of the application might accept non-integer values for the input field designed to get the number of bottles from the user

Test analysis for system testing has just begun and the following test conditions have been identified.

TC-SEL-2. Test the selection of the package sizes

TC-SEL-4. Test wrong numbers of bottles for an order

TC-CR-RSK-1. Test the accepted values from the input field designed to get the number of bottles from the user

What is the MINIMUM number of test conditions that must be added to fulfill both the EXCR1 and EXCR2 exit criteria?

Exactly! It all adds up to 4 test conditions.

Jaleesa 20 days ago

So, we definitely need TC-CR-RSK-1 for that.

Cherry 26 days ago

Right! Plus, we can't forget about the quality risk item.

Lashawnda 1 month ago

I believe the answer is 4. We need TC-SEL-1 and TC-PAY-1 too.

Jaleesa 1 month ago

Agreed! We have to ensure each requirement is tested.

Cherry 1 month ago

This question is tricky. I think we need to cover all critical requirements.

Jenelle 2 months ago

Definitely need to cover that GUI risk, so 4 makes sense to me!

Michael 2 months ago

I think 3 could work if we combine some tests effectively.

Maybelle 2 months ago

Wait, are we sure 4 is the right number? Seems like a lot.

Eva 2 months ago

Totally agree, can't skip any critical requirements!

Argelia 2 months ago

Looks like we need at least 4 test conditions to cover everything.

Olive 2 months ago

I believe we have three test conditions already, but I’m uncertain if that’s enough to meet both exit criteria.

Elden 3 months ago

I feel like we practiced a similar question where we had to ensure all risks were addressed. I hope I can apply that here.

Billye 3 months ago

I think we might need to add a test condition for REQ-PAY-1 since it’s critical for payment processing.

Jenise 3 months ago

I remember we discussed how each critical requirement needs at least one test condition, but I'm not sure if we've covered all of them here.
