path coverage testing
     
         Testing a program by examining which lines of
        executable code are visited (as in {code coverage testing})
        and also the ways of getting to each line of code and the
        subsequent sequence of execution.
     
        Path coverage testing is the most comprehensive type of
        testing that a {test suite} can provide.  It can find more
        {bugs} in a program, especially those that are caused by {data
        coupling}.  However, path coverage is a testing level that is
        very hard to achieve, and usually only small and/or critical
        sections of code are checked in this way.
