​Importance of Data Testing

to make sure that the program...

• ​meets the program requirements

• fully works

• does not crash

• does not have bugs

​Types of Test Data

• ​Normal - data that the program should be accepted

• ​Abnormal - data that the program that should not be accepted

• Extreme - data​ that is at the edge of what is allowed

• ​Boundary - data that is on edge of being accepted and being rejected

Normal Test Data

​valid data that the code would be expected to accept

​

​Example:

​A program that requires an integer in the range 1-100

​

​Normal Test Data: 50
