Revise: Refining AlgorithmsEach test needs a specific input and a clear expected result: what should happen according to the requirements. Write this prediction before carrying out the test. Otherwise, it is easy to assume that whatever the algorithm produces must be correct.
Give specific input values and precise expected results, not just test-data category names.
Use the stated requirements to decide the expected result; do not copy the algorithm’s output into that column.
A test passes when actual and expected results match. Correctly rejecting unsuitable input is a successful test.
