=head1 NAME
prove -- A command-line tool for running tests against Test::Harness
=head1 SYNOPSIS
prove [options] [files/directories]
=head1 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.
=head1 OVERVIEW
F<prove> is a command-line interface to the test-running functionality
of C<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 C<File::Glob::bsd_glob>.
=head1 PROVE VS. "MAKE TEST"
F<prove> has a number of advantages over C<make test> when doing development.
=over 4
=item * F<prove> is designed as a development tool
Perl users typically run the test harness through a makefile via
C<make test>. That's fine for module distributions, but it's
suboptimal for a test/code/debug development cycle.
=item * F<prove> is granular
F<prove> lets your run against only the files you want to check.
Running C<prove t/live/ t/master.t> checks every F<*.t> in F<t/live>,
plus F<t/master.t>.
=item * F<prove> has an easy verbose mode
F<prove> has a C<-v> option to see the raw output from the tests.
To do this with C<make test>, you must set C<HARNESS_VERBOSE=1> in
the environment.
=item * F<prove> can run under taint mode
F<prove>'s C<-T> runs your tests under C<perl -T>, and C<-t> runs them
under C<perl -t>.
=item * F<prove> can shuffle tests
You can use F<prove>'s C<--shuffle> option to try to excite problems
that don't show up when tests are run in the same order every time.
=item * F<prove> doesn't rely on a make tool
Not everyone wants to write a makefile, or use L<ExtUtils::MakeMaker>
to do so. F<prove> has no external dependencies.
=item * 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.
=back
=head1 COMMAND LINE OPTIONS
=head2 -b, --blib
Adds blib/lib to the path for your tests, a la "use blib".
=head2 -d, --debug
Include debug information about how F<prove> is being run. This
option doesn't show the output from the test scripts. That's handled
by -v,--verbose.
=head2 -D, --dry
Dry run: Show the tests to run, but don't run them.
=head2 -I
Add libraries to @INC, as Perl's -I.
=head2 -l, --lib
Add C<lib> to @INC. Equivalent to C<-Ilib>.
=head2 --perl
Sets the C<HARNESS_PERL> environment variable, which controls what
Perl executable will run the tests.
=head2 -r, --recurse
Descends into subdirectories of any directories specified, looking for tests.
=head2 -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.
=head2 --strap
Sets the HARNESS_STRAP_CLASS variable to set which Test::Harness::Straps
variable to use in running the tests.
=head2 -t
Runs test programs under perl's -t taint warning mode.
=head2 -T
Runs test programs under perl's -T taint mode.
=head2 --timer
Print elapsed time after each test file
=head2 -v, --verbose
Display standard output of test scripts while running them. Also sets
TEST_VERBOSE in case your tests rely on them.
=head2 -V, --version
Display version info.
=head1 BUGS
Please use the CPAN bug ticketing system at L<http://rt.cpan.org/>.
You can also mail bugs, fixes and enhancements to
C<< <bug-test-harness@rt.cpan.org> >>.
=head1 TODO
=over 4
=item *
Shuffled tests must be recreatable
