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 dont run them
-h, --help Display this help
-H, --man Longer manpage for prove
-I Add libraries to @INC, as Perls -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 testwhen doing development.
o |
prove is designed as a development tool
Perl users typically run the test harness through a makefile via make test. Thats fine for module distributions, but its suboptimal for a test/code/debug development cycle. |
o |
prove is granular
prove lets your run against only the files you want to check. Running prove t/live/ t/master.tchecks every *.t in t/live, plus t/master.t. |
o |
prove has an easy verbose mode
prove has a -voption to see the raw output from the tests. To do this with make test, you must set HARNESS_VERBOSE=1in the environment. |
o |
prove can run under taint mode
proves -Truns your tests under perl -T, and -truns them under perl -t. |
o |
prove can shuffle tests
You can use proves --shuffleoption to try to excite problems that dont show up when tests are run in the same order every time. |
o |
prove doesnt rely on a make tool
Not everyone wants to write a makefile, or use ExtUtils::MakeMaker to do so. prove has no external dependencies. |
o |
Not everything is a module
More and more users are using Perls 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 doesnt show the output from the test scripts. Thats handled by -v,--verbose.
\-D, \-\-dry
Dry run: Show the tests to run, but dont run them.
\-I
Add libraries to
@INC, as Perls -I.
\-l, \-\-lib
Add
libto
@INC. Equivalent to
-Ilib.
\-\-perl
Sets the
HARNESS_PERLenvironment 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 perls -t taint warning mode.
\-T
Runs test programs under perls -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.
