QA · Senior · Theory

Tell me when you use pairwise testing, and in which cases it can miss a serious defect.

~4 min by voice

How to approach it

The interviewer checks whether the candidate understands the mathematical essence of pairwise (covering all pairs, not all combinations), its empirical justification and the limits of where it applies, and whether they can compensate for the technique's weak spots: t-wise, constraints, manual business scenarios.

You're given a business rule for calculating a discount that depends on the order total, the customer's status and a promo code. How would you design tests for it? Senior In an online store, the discount depends on three conditions: whether the customer has a loyalty card, whether the order total is over $100, and whether this is their first order. How would you design the tests so that you don't miss a single combination? Junior There's a function is_valid_password: it takes a string and returns true or false. A password is valid if it has 8 to 20 characters, at least one digit, and at least one uppercase Latin letter. You don't have the function's code; write a set of automated tests for it. Junior An online store's discount depends on the customer's status, the order total and whether there's a promo code, and the rules overlap in places. How would you design tests for this logic? Mid-level A checkout form has four payment methods, three delivery methods, five regions, and a "have a promo code" checkbox. Testing every combination exhaustively takes too long. How would you reduce the test set, and what are you risking by doing that? Mid-level
