Suppose a restaurant sells soft tacos, crunchy tacos, hamburgers with cheese, hamburgers without cheese, and fried chicken. your coverage criterion says to taste each type of dish, one option for all dishes is to serve them with very hot sriracha sauce; so much that it completely covers the taste of the rest of the ingredients. if your boss told you to taste the items without the sriracha sauce, what kind of testing problem would that avoid?
a) redundancy
b) coverage
c) controllability
