       prove - A command-line tool for running tests against Test::Harness

SYNOPSIS
       prove [options] [files/directories]

       Options:

           -b, -blib      Adds blib/lib to the path for your tests, a la "use blib".
           -d, -debug     Includes extra debugging information.
           -D, -dry       Dry run: Show the tests to run, but don't run them.
               -ext=x     Extensions (defaults to .t)
           -h, -help      Display this help
           -H, -man       Longer manpage for prove
           -I              Add libraries to @INC, as Perl's -I
           -l, -lib       Add lib to the path for your tests.
           -r, -recurse   Recursively descend into directories.
           -s, -shuffle   Run the tests in a random order.
           -T              Enable tainting checks
           -t              Enable tainting warnings
           -v, -verbose   Display standard output of test scripts while running them.
           -V, -version   Display version info

       Single-character options may be stacked.  Default options may be set by
       specifying the PROVESWITCHES environment variable.

OOVVEERRVVIIEEWW
       prove is a command-line interface to the test-running functionality of
       "Test::Harness".  With no arguments, it will run all tests in the cur-
       rent directory.

       Shell metacharacters may be used with command lines options and will be
       exanded via "glob".

PPRROOVVEE VVSS.. ""MMAAKKEE TTEESSTT""
       prove has a number of advantages over "make test" when doing develop-
       ment.

       * prove is designed as a development tool
           Perl users typically run the test harness through a makefile via
           "make test".  That's fine for module distributions, but it's subop-
           timal for a test/code/debug development cycle.

       * prove is granular
           prove lets your run against only the files you want to check.  Run-
           ning "prove t/live/ t/master.t" checks every *.t in t/live, plus
           t/master.t.

       * prove has an easy verbose mode
           prove has a "-v" option to see the raw output from the tests.  To
           do this with "make test", you must set "HARNESSVERBOSE=1" in the
           environment.

       * prove can run under taint mode
           prove's "-T" runs your tests under "perl -T", and "-t" runs them
           under "perl -t".

       * prove can shuffle tests
           You can use prove's "-shuffle" option to try to excite problems
           that don't show up when tests are run in the same order every time.

       * prove doesn't rely on a make tool
           Not everyone wants to write a makefile, or use ExtUtils::MakeMaker
           to do so.  prove has no external dependencies.

       * Not everything is a module
           More and more users are using Perl's testing tools outside the con-
           text of a module distribution, and may not even use a makefile at
           all.

CCOOMMMMAANNDD LLIINNEE OOPPTTIIOONNSS
       -bb,, --bblliibb

       Adds blib/lib to the path for your tests, a la "use blib".

       -dd,, --ddeebbuugg

       Include debug information about how prove is being run.  This option
       doesn't show the output from the test scripts.  That's handled by
       -v,-verbose.

       -DD,, --ddrryy

       Dry run: Show the tests to run, but don't run them.

       --eexxtt==eexxtteennssiioonn

       Specify extensions of the test files to run.  By default, these are .t,
       but you may have other non-.t test files, most likely .sh shell
       scripts.  The -ext is repeatable.

       -II

       Add libraries to @INC, as Perl's -I.

       -ll,, --lliibb

       Add "lib" to @INC.  Equivalent to "-Ilib".

       -rr,, --rreeccuurrssee

       Descends into subdirectories of any directories specified, looking for
       tests.

       -ss,, --sshhuuffffllee

       Sometimes tests are accidentally dependent on tests that have been run
       before.  This switch will shuffle the tests to be run prior to running
       them, thus ensuring that hidden dependencies in the test order are
       likely to be revealed.  The author hopes the run the algorithm on the
       preceding sentence to see if he can produce something slightly less
       awkward.

       -tt

       Runs test programs under perl's -t taint warning mode.

       -TT

       Runs test programs under perl's -T taint mode.

       -vv,, --vveerrbboossee

       Display standard output of test scripts while running them.  Also sets
       TESTVERBOSE in case your tests rely on them.

       -VV,, --vveerrssiioonn

       Display version info.
