Learning Intention I will learn about testing programs.

Analysis Design Implementation Testing Documentation Evaluation

Testing building your interface and typing the code is not enough to prove your program works when you buy an app or a game you expect it to work you need to test your program to prove it works and has no bugs

Testing all software needs to be tested to make sure it works – customers expect what they buy to work! testing needs to be planned and structured

Testing best way to test is to calculate the expected result before you run the program you can then check that you get the result you expected

Testing e.g. a program for adding two numbers together Number1 Number2 Expected Actual 2 5 7 1 -10 15 7 1

Testing test data can be categorised as follows: Normal Data within the expected range. Tests normal conditions. Extreme Data on the edge of the expected range. Tests limits. Exceptional Unexpected data. Data outwith allowed range.

Testing e.g. program which takes in test marks out of 15 Normal: 1, 3, 8, 12 (1-14) Extreme: 0, 15 Exceptional: -1, 16, [Ten, Batman, @]

Testing e.g. program which takes in player rating marks out of 100 Normal: Extreme: Exceptional: 1, 22, 66, 99 0, 100 -1, 101

What type of test data? A program takes in runners names and the lane on the track that they are running in. There are 8 lanes on the track numbered 1 to 8. What type of test data are the following lane number values? 7 12 1 Normal Exceptional Extreme

Testing Tasks Complete the Testing worksheet.

Success Criteria I can identify Normal, Extreme and Exceptional test data for a given problem.
