prove -- A command-line tool for running tests against Test::Harness
prove [options] [files/directories]
-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 PROVE_SWITCHES environment variable.
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-
Shell metacharacters may be used with command lines options and will be
exanded via "glob".
PROVE VS. "MAKE TEST"
prove has a number of advantages over "make test" when doing develop-
* 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
* 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
* 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
COMMAND LINE OPTIONS
Adds blib/lib to the path for your tests, a la "use blib".
Include debug information about how prove is being run. This option
doesn’t show the output from the test scripts. That’s handled by
Dry run: Show the tests to run, but don’t run them.
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.
Add libraries to @INC, as Perl’s -I.
Add "lib" to @INC. Equivalent to "-Ilib".
Descends into subdirectories of any directories specified, looking for
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

Runs test programs under perl’s -t taint warning mode.
Runs test programs under perl’s -T taint mode.
Display standard output of test scripts while running them. Also sets
TEST_VERBOSE in case your tests rely on them.
