21. What is DRE?
To
measure test effectiveness a powerful metric is used to measure test
effectiveness known as DRE (Defect Removal Efficiency).
From this metric we would know how many bugs
we have found from the set of test cases. Formula for calculating DRE is
DRE=Number
of bugs while testing / number of bugs while testing + number of bugs
found by user
22. What are Test comparators?
Is it
really a test if you put some inputs into some software, but never look to see
whether the software produces the correct result? The essence of testing is to
check whether the software produces the correct result, and to do that, we must
compare what the software products to what it should produce.
A test
comparator helps to automate aspects of that comparison.
