NAMEprove -- A command-line tool for running tests against Test::Harness
SYNOPSISprove [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
OVERVIEWprove 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.
PROVE VS. MAKE TESTprove 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, --blibAdds blib/lib to the path for your tests, a la ``use blib''.
-d, --debugInclude 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, --dryDry run: Show the tests to run, but don't run them.
--ext=extensionSpecify 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.
-IAdd libraries to @INC, as Perl's -I.
-l, --libAdd "lib" to @INC. Equivalent to "-Ilib".
-r, --recurseDescends into subdirectories of any directories specified, looking for tests.
-s, --shuffleSometimes 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.
-tRuns test programs under perl's -t taint warning mode.
-TRuns test programs under perl's -T taint mode.
-v, --verboseDisplay standard output of test scripts while running them. Also sets TEST_VERBOSE in case your tests rely on them.
-V, --versionDisplay version info.

- Shuffled tests must be recreatable
