NAME
       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
           -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
               --perl      Sets the name of the Perl executable to use
           -r, --recurse   Recursively descend into directories
           -s, --shuffle   Run the tests in a random order
               --strap     Define strap class to use
           -T              Enable tainting checks
           -t              Enable tainting warnings
               --timer     Print elapsed time after each test file
           -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 PROVE_SWITCHES
       environment variable.

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

       Shell metacharacters may be used with command lines options and will be exanded via
       "File::Glob::bsd_glob".

PROVE VS. "MAKE TEST"
       prove has a number of advantages over "make test" when doing development.

       •   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 suboptimal for a test/code/debug development cycle.

       •   prove is granular

           prove lets your run against only the files you want to check.  Running "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 "HARNESS_VERBOSE=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 context of a module distribution,
           and may not even use a makefile at all.

COMMAND LINE OPTIONS
       -b, --blib

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

       -d, --debug

       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.

       -D, --dry

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

       -I

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

       -l, --lib

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

       --perl

       Sets the "HARNESS_PERL" environment variable, which controls what Perl executable will run the tests.

       -r, --recurse

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

       -s, --shuffle

       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.

       --strap

       Sets the HARNESS_STRAP_CLASS variable to set which Test::Harness::Straps variable to use in running
       the tests.

       -t

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

       -T

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

       --timer

       Print elapsed time after each test file

       -v, --verbose

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

       -V, --version

       Display version info.
