Good testing Involves much more than just running the program a few times to see whether it works. Thorough analysis of the program lets you test more systematically and more effectively. This chapter introduces this book by Illustrating how an experienced tester could approach the early testing of a simple program To keep the example easy to understand we made the program almost ridiculously simple. But we did give it some errors that you ll see often In real programs. THE FIRST CYCLE OF TESTING Y ou ve been given the program and the following description of it The program is designed to add two numbers which you enter. Each number should be one or two digits. The program will echo your entries then print the sum. Press Enter after each number. To start the program type ADDER. Figure A first test of the program What you do What happens Type ADDER and press the The screen blanks. You see a question mark at the top of Enter key screen. Press 2 A 2 appears after the question mark. Press Enter A question mark appears on the next line. Press A 3 appears after the second question mark. Press Enter A 5 appears on the third line.
