1. Learning Intention
I will learn about testing programs.

2. Analysis
Design
Implementation
Testing
Documentation
Evaluation

3. 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

4. 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

5. 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

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

7. 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.

8. 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,

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

10. 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

11. Testing Tasks
Complete the Testing worksheet.

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