Why is validation a difficult process?

1 Answer. Component validation without source code is very difficult because there is no way of assessing how the component handles exceptions (and this is rarely defined in a component specification). The only validation method that can be used is black-box testing so static techniques cannot be used.

What is an example of validation?

Validation is an automatic computer check to ensure that the data entered is sensible and reasonable. It does not check the accuracy of data. For example, a secondary school student is likely to be aged between 11 and 16. For example, a student’s age might be 14, but if 11 is entered it will be valid but incorrect.
