Software testing approaches
that examine the program structure and derive test data from the program logic.
Structural testing is sometimes referred to as clear-box testing since white
boxes are considered opaque and do not really permit visibility into the code.
Types of Glass Box Testing:
Dynamic Analysis: static analysis techniques do not necessitate the execution of
the software, dynamic analysis is what is generally considered as ``testing``,
i.e. it involves running the system.
Coverage: Testing performed where every statement is executed at least once.
Running a series of tests to ensure that all branches are tested at least once.
Testing all paths.
All-Definition-use-path coverage: All paths between the definition of a variable
and the use of that definition are now identified and tested.
1) Forces test developer to reason carefully about implementation
2) Approximates the partitioning done by execution equivalence
3) Reveals errors in "hidden" code
4) Beneficent side-effects
2) Miss cases omitted in the code
