Selecting & Using Suitable Test Data Flashcards

All 7 cards in this deck

What is normal test data?: Data which should be accepted by the program without causing errors.
What is boundary test data?: Data of the correct type which is on the very edge of being valid, i.e. at either edge of the accepted range.
What is invalid test data?: Data of the correct data type which should be rejected by the program.
What is erroneous test data?: Data of the incorrect data type which should be rejected by the program, e.g. letters entered where a number is required.
A program accepts a height jumped from 40 cm to 180 cm. Which values are the boundary test data, and what output is expected?: 40 and 180 — both should output "VALID".
A program accepts a height jumped from 40 cm to 180 cm. Give one erroneous test value and the expected output.: A non-numeric value such as abc — expected output "NOT VALID".
True or false? Writing "a value between 40 and 180" in the test data column of a test plan is acceptable.: False. Test data must be actual data, e.g. 50, not a description of the data.
