Extreme Data
Extreme Data : (ICT) When you have developed a new system you want to make sure that it works properly. One of the things that you will test is your validation rules. Lets look at an example: Validation Rule: >=10 and <=100. This validation rule should accept all data between (and inclusive) 10 and 100. You would test this rule by entering some extreme data - right on the edges or near to the edges of the validation rule. Extreme data in this case could be 10, 11, 99, 100. If the system is working properly then it should accept the extreme data
