Code contracts allow you to make these promises, and the compiler can use them to loosen compile-time checks.

White box testing is a software testing approach based on an analysis of the internal structure of the component or system. Internal structure may include code, architecture, integrations, and data flows of a system. The more code is tested, the less likely it is to have defects, and any defects found will have less severity.
