Feature Based Testing

Question

I was asked this question during an interview. Say that your product has 10 features but you only have time to test 5 of them. How do you decide which ones to test.

Answer

There is no single correct answer for this question. I would calculate a score for each feature and start testing those with the highest score. Score can be calculated based on a combination of factors including feature priority, business needs, to what extent other product functionalities depend on the feature, etc
