       Additional option files may be specified with the "--rc" option.
       Default option file processing is disabled by the "--norc" option.

       Under Windows and VMS the option file is named _proverc rather than
       .proverc and is sought only in the current directory.

   Reading from "STDIN"
       If you have a list of tests (or URLs, or anything else you want to
       test) in a file, you can add them to your tests by using a '-':

        prove - < my_list_of_things_to_test.txt

       See the "README" in the "examples" directory of this distribution.

   Default Test Directory
       If no files or directories are supplied, "prove" looks for all files
       matching the pattern "t/*.t".

   Colored Test Output
       Colored test output is the default, but if output is not to a terminal,
       color is disabled. You can override this by adding the "--color"

       Color support requires Term::ANSIColor on Unix-like platforms and
       Win32::Console windows. If the necessary module is not installed
       colored output will not be available.

   Exit Code
       If the tests fail "prove" will exit with non-zero status.

   Arguments to Tests
       It is possible to supply arguments to tests. To do so separate them
       from prove's own arguments with the arisdottle, '::'. For example

        prove -v t/mytest.t :: --url

       would run t/mytest.t with the options '--url'.  When
       running multiple tests they will each receive the same arguments.

       Normally you can just pass a list of Perl tests and the harness will
       know how to execute them.  However, if your tests are not written in
       Perl or if you want all tests invoked exactly the same way, use the
       "-e", or "--exec" switch:

        prove --exec '/usr/bin/ruby -w' t/
        prove --exec '/usr/bin/perl -Tw -mstrict -Ilib' t/
        prove --exec '/path/to/my/customer/exec'

       If you need to make sure your diagnostics are displayed in the correct
       order relative to test results you can use the "--merge" option to
       merge the test scripts' STDERR into their STDOUT.
       run and display the test summary even if the run is interrupted

       You can ask "prove" to remember the state of previous test runs and
       select and/or order the tests to be run based on that saved state.

       The "--state" switch requires an argument which must be a comma
       separated list of one or more of the following options.

           Run the same tests as the last time the state was saved. This makes
           it possible, for example, to recreate the ordering of a shuffled

               # Run all tests in random order
               $ prove -b --state=save --shuffle

               # Run them again in the same order
               $ prove -b --state=last

           Run only the tests that failed on the last run.

               # Run all tests
               $ prove -b --state=save

               # Run failures
               $ prove -b --state=failed

           If you also specify the "save" option newly passing tests will be
           excluded from subsequent runs.

               # Repeat until no more failures
               $ prove -b --state=failed,save

           Run only the passed tests from last time. Useful to make sure that
           no new problems have been introduced.

           Run all tests in normal order. Multple options may be specified, so
           to run all tests with the failures from last time first:

               $ prove -b --state=failed,all,save

           Run the tests that most recently failed first. The last failure
           time of each test is stored. The "hot" option causes tests to be
           run in most-recent- failure order.

               $ prove -b --state=hot,save

           Tests that have never failed will not be selected. To run all tests
           with the most recently failed first use
           conjunction with the "-j" parallel testing switch to ensure that
           your slowest tests start running first.

               $ prove -b --state=slow -j9

           Run test tests in fastest to slowest order.

           Run the tests in newest to oldest order based on the modification
           times of the test scripts.

           Run the tests in oldest to newest order.

           Run those test scripts that have been modified since the last test

           Save the state on exit. The state is stored in a file called .prove
           (_prove on Windows and VMS) in the current directory.

       The "--state" switch may be used more than once.

           $ prove -b --state=hot --state=all,save

       prove introduces a separation between "options passed to the perl which
       runs prove" and "options passed to the perl which runs tests"; this
       distinction is by design. Thus the perl which is running a test starts
       with the default @INC. Additional library directories can be added via
       the "PERL5LIB" environment variable, via -Ifoo in "PERL5OPT" or via the
       "-Ilib" option to prove.

   Taint Mode
       Normally when a Perl program is run in taint mode the contents of the
       "PERL5LIB" environment variable do not appear in @INC.

       Because "PERL5LIB" is often used during testing to add build
       directories to @INC prove passes the names of any directories found in
       "PERL5LIB" as -I switches. The net effect of this is that "PERL5LIB" is
       honoured even when prove is run in taint mode.

       You can load a custom TAP::Parser::Formatter:

         prove --formatter MyFormatter

       You can load custom TAP::Parser::SourceHandlers, to change the way the
       parser interprets particular sources of TAP.

         prove --source MyHandler --source YetAnother t

       separated by a "=", as in the "pset=" examples above (escape "=" with a

       All "--sources" are combined into a hash, and passed to "new" in
       TAP::Harness's "sources" parameter.

       See TAP::Parser::IteratorFactory for more details on how configuration
       is passed to SourceHandlers.

       Plugins can be loaded using the "-Pplugin" syntax, eg:

         prove -PMyPlugin

       This will search for a module named "App::Prove::Plugin::MyPlugin", or
       failing that, "MyPlugin".  If the plugin can't be found, "prove" will
       complain & exit.

       You can pass arguments to your plugin by appending "=arg1,arg2,etc" to
       the plugin name:

         prove -PMyPlugin=fou,du,fafa

       Please check individual plugin documentation for more details.
