 You will also perform *whitebox testing* of part of your code. In the
 Calculator assignment you developed a set of test cases based on the blackbox
-specification. Rarely will such a test suite fully exercise the code. In
-cooperation with a partner, extend your test suite such that each statement in
-the source code is executed at least once. (Note also that whitebox testing
-will rarely cover the blackbox specification. In practice, a combination of
-blackbox and whitebox testing is necessary.)
