prove -- A command-line tool for running tests against Test::Harness
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 --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.
prove is a command-line interface to the test-running func- tionality 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 "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 dis- tributions, 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. perl v5.8.8 2006-06-30 1 PROVE(1) Perl Programmers Reference Guide PROVE(1) * 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 out- side the context of a module distribution, and may not even use a makefile at all.
-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. --ext=extension 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. -I Add libraries to @INC, as Perl's -I. perl v5.8.8 2006-06-30 2 PROVE(1) Perl Programmers Reference Guide PROVE(1) -l, --lib Add "lib" to @INC. Equivalent to "-Ilib". -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 sen- tence to see if he can produce something slightly less awk- ward. -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.
