There are 3 kinds of test data that you need to know about. You should also be able to give examples of data for a piece of code shown:
Normal – data within the expected range for a program (e.g. 45 for a program expecting a mark between 1 and 100)
Boundary - data on the edge of the expected range (e.g. 1 or 100)
Out of Range – data not expected by the program (e.g. “fifteen”, -1)
Apart from that we discussed the terms comprehensive and systematic. See powerpoint for details.
