NAME

       Test::Script - Basic cross-platform tests for scripts

DESCRIPTION

       The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or
       bin as is also commonly used) paths of your Perl distribution.

       Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible.

       That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is
       considered unacceptable.

       In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking
       that your module won't on some platform because of the dependency.

       Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform
       safety.

FUNCTIONS

   script_compiles
	   script_compiles( 'script/foo.pl', 'Main script compiles' );

       The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl).
       This will also be shown in the diagnostic output on failure.

   script_runs
	   script_runs( 'script/foo.pl', 'Main script runs' );

       The "script_runs" test executes the script with "perl script.pl" and checks that it returns success.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also
       be shown in the diagnostic output on failure.
