How to approach it

The interviewer wants to see whether you know combinatorial test design techniques, above all pairwise, and can apply them sensibly: understand why the method works, where it's weak, and how to tailor the set to the real product.

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