## White-box validation [Power / Sample Size]

Hi Helmut,

» Since PowerTOST is open-source you (or an -expert) can perform a white-box validation.

Citing Wiki:

The programmer must have a deep understanding of the application to know what kinds of test cases to create so that every visible path is exercised for testing.

Well... Since PowerTOST is a Swiss army knife, it will take a lot of efforts to cover it

Kind regards,
Mittyri
