Пакет perl-Tie-Filehandle-Preempt-Stdin: Информация

Suppose a program requires manual input from the keyboard operator.
How do we test that we have properly handled operator input?  More
specifically, how do we incorporate testing for user input in files
built on Perl's standard testing apparatus ("Test::Simple",
"Test::More", etc.)?

Tie::Filehandle::Preempt::Stdin offers one way to do it -- a relatively
simple and unsophisticated todo it.  The most difficult part is
analyzing the program to be tested so that you recognize all the points
at which input is needed via STDIN.  This in turn requires an
understanding of all the different branches your program flow can take
in response to standard input.  Once you know that, you construct a list
of dummy data that will be fed to each test at the points the program,
when put into production, would normally prompt for operator input.
This list of dummy data 'pre-empts' standard input via a tie of
filehandle STDIN; hence, the module's name.
