+=head1 SYNOPSIS
+
+ use Test::Harness;
+
+ runtests(@test_files);
+
+=head1 DESCRIPTION
+
+B<STOP!> If all you want to do is write a test script, consider
+using Test::Simple. Test::Harness is the module that reads the
+output from Test::Simple, Test::More and other modules based on
+Test::Builder. You don't need to know about Test::Harness to use
+those modules.
+
+Test::Harness runs tests and expects output from the test in a
+certain format. That format is called TAP, the Test Anything
+Protocol. It is defined in L<Test::Harness::TAP>.
+
+C<Test::Harness::runtests(@tests)> runs all the testscripts named
+as arguments and checks standard output for the expected strings
+in TAP format.
+
+The F<prove> utility is a thin wrapper around Test::Harness.
+
+=head2 Taint mode
+
+Test::Harness will honor the C<-T> or C<-t> in the #! line on your
+test files. So if you begin a test with:
+
+ #!perl -T
+
+the test will be run with taint mode on.
+
+=head2 Configuration variables.
+
+These variables can be used to configure the behavior of
+Test::Harness. They are exported on request.
+
+=over 4
+
+=item C<$Test::Harness::Verbose>
+
+The package variable C<$Test::Harness::Verbose> is exportable and can be
+used to let C<runtests()> display the standard output of the script
+without altering the behavior otherwise. The F<prove> utility's C<-v>
+flag will set this.
+
+=item C<$Test::Harness::switches>
+
+The package variable C<$Test::Harness::switches> is exportable and can be
+used to set perl command line options used for running the test
+script(s). The default value is C<-w>. It overrides C<HARNESS_SWITCHES>.
+
+=back
+
+
+=head2 Failure
+
+When tests fail, analyze the summary report:
+
+ t/base..............ok
+ t/nonumbers.........ok
+ t/ok................ok
+ t/test-harness......ok
+ t/waterloo..........dubious
+ Test returned status 3 (wstat 768, 0x300)
+ DIED. FAILED tests 1, 3, 5, 7, 9, 11, 13, 15, 17, 19
+ Failed 10/20 tests, 50.00% okay
+ Failed Test Stat Wstat Total Fail Failed List of Failed
+ -----------------------------------------------------------------------
+ t/waterloo.t 3 768 20 10 50.00% 1 3 5 7 9 11 13 15 17 19
+ Failed 1/5 test scripts, 80.00% okay. 10/44 subtests failed, 77.27% okay.
+
+Everything passed but F<t/waterloo.t>. It failed 10 of 20 tests and
+exited with non-zero status indicating something dubious happened.
+
+The columns in the summary report mean:
+
+=over 4
+
+=item B<Failed Test>
+
+The test file which failed.
+
+=item B<Stat>
+
+If the test exited with non-zero, this is its exit status.
+
+=item B<Wstat>
+
+The wait status of the test.
+
+=item B<Total>
+
+Total number of tests expected to run.
+
+=item B<Fail>
+
+Number which failed, either from "not ok" or because they never ran.
+
+=item B<Failed>
+
+Percentage of the total tests which failed.
+
+=item B<List of Failed>
+
+A list of the tests which failed. Successive failures may be
+abbreviated (ie. 15-20 to indicate that tests 15, 16, 17, 18, 19 and
+20 failed).

+This runs all the given I<@test_files> and divines whether they passed
+or failed based on their output to STDOUT (details above). It prints
+out each individual test which failed along with a summary report and
+a how long it all took.
-sub globdir { opendir DIRH, shift; my @f = readdir DIRH; closedir DIRH; @f }
+It returns true if everything was ok. Otherwise it will C<die()> with
+one of the messages in the DIAGNOSTICS section.

-Test::Harness - run perl standard test scripts with statistics
+=cut
-=head1 SYNOPSIS
-use Test::Harness;
+1;
+__END__
-runtests(@tests);
-=head1 DESCRIPTION
+=head1 EXPORT
-(By using the L<Test> module, you can write test scripts without
-knowing the exact output this module expects. However, if you need to
-know the specifics, read on!)
+C<&runtests> is exported by Test::Harness by default.
-Perl test scripts print to standard output C<"ok N"> for each single
-test, where C<N> is an increasing sequence of integers. The first line
-output by a standard test script is C<"1..M"> with C<M> being the
-number of tests that should be run within the test
-script. Test::Harness::runtests(@tests) runs all the testscripts
-named as arguments and checks standard output for the expected
-C<"ok N"> strings.
+C<$verbose>, C<$switches> and C<$debug> are exported upon request.
-After all tests have been performed, runtests() prints some
-performance statistics that are computed by the Benchmark module.
+=head1 DIAGNOSTICS
-=head2 The test script output
+=over 4
-Any output from the testscript to standard error is ignored and
-bypassed, thus will be seen by the user. Lines written to standard
-output containing C</^(not\s+)?ok\b/> are interpreted as feedback for
-runtests(). All other lines are discarded.
+=item C<All tests successful.\nFiles=%d, Tests=%d, %s>
-It is tolerated if the test numbers after C<ok> are omitted. In this
-case Test::Harness maintains temporarily its own counter until the
-script supplies test numbers again. So the following test script
+If all tests are successful some statistics about the performance are
+printed.
- print <<END;
- 1..6
- not ok
- ok
- not ok
- ok
- ok
- END
+=item C<FAILED tests %s\n\tFailed %d/%d tests, %.2f%% okay.>
-will generate
+For any single script that has failing subtests statistics like the
+above are printed.
- FAILED tests 1, 3, 6
- Failed 3/6 tests, 50.00% okay
+=item C<Test returned status %d (wstat %d)>
-The global variable $Test::Harness::verbose is exportable and can be
-used to let runtests() display the standard output of the script
-without altering the behavior otherwise.
+Scripts that return a non-zero exit status, both C<$? E<gt>E<gt> 8>
+and C<$?> are printed in a message similar to the above.
-The global variable $Test::Harness::switches is exportable and can be
-used to set perl command line options used for running the test
-script(s). The default value is C<-w>.
+=item C<Failed 1 test, %.2f%% okay. %s>
-If the standard output line contains substring C< # Skip> (with
-variations in spacing and case) after C<ok> or C<ok NUMBER>, it is
-counted as a skipped test. If the whole testscript succeeds, the
-count of skipped tests is included in the generated output.
+=item C<Failed %d/%d tests, %.2f%% okay. %s>
-C<Test::Harness> reports the text after C< # Skip(whatever)> as a
-reason for skipping. Similarly, one can include a similar explanation
-in a C<1..0> line emitted if the test is skipped completely:
+If not all tests were successful, the script dies with one of the
+above messages.
- 1..0 # Skipped: no leverage found
+=item C<FAILED--Further testing stopped: %s>
-=head1 EXPORT
+If a single subtest decides that further testing will not make sense,
+the script dies with this message.
-C<&runtests> is exported by Test::Harness per default.

+Test::Harness sets these before executing the individual tests.

+=item C<HARNESS_COLUMNS>
-If not all tests were successful, the script dies with one of the
-above messages.
+This value will be used for the width of the terminal. If it is not
+set then it will default to C<COLUMNS>. If this is not set, it will
+default to 80. Note that users of Bourne-sh based shells will need to
+C<export COLUMNS> for this module to use that variable.
-=back
+=item C<HARNESS_COMPILE_TEST>
+
+When true it will make harness attempt to compile the test using
+C<perlcc> before running it.
-=head1 ENVIRONMENT
+B<NOTE> This currently only works when sitting in the perl source
+directory!
-Setting C<HARNESS_IGNORE_EXITCODE> makes harness ignore the exit status
-of child processes.
+=item C<HARNESS_DEBUG>
-Setting C<HARNESS_NOTTY> to a true value forces it to behave as though
-STDOUT were not a console. You may need to set this if you don't want
-harness to output more frequent progress messages using carriage returns.
-Some consoles may not handle carriage returns properly (which results
-in a somewhat messy output).
+If true, Test::Harness will print debugging information about itself as
+it runs the tests. This is different from C<HARNESS_VERBOSE>, which prints
+the output from the test being run. Setting C<$Test::Harness::Debug> will
+override this, or you can use the C<-d> switch in the F<prove> utility.
-Setting C<HARNESS_COMPILE_TEST> to a true value will make harness attempt
-to compile the test using C<perlcc> before running it.
+=item C<HARNESS_FILELEAK_IN_DIR>
-If C<HARNESS_FILELEAK_IN_DIR> is set to the name of a directory, harness
-will check after each test whether new files appeared in that directory,
-and report them as
+When set to the name of a directory, harness will check after each
+test whether new files appeared in that directory, and report them as
LEAKED FILES: scr.tmp 0 my.db
If relative, directory name is with respect to the current directory at
the moment runtests() was called. Putting absolute path into
-C<HARNESS_FILELEAK_IN_DIR> may give more predicatable results.
+C<HARNESS_FILELEAK_IN_DIR> may give more predictable results.
+
+=item C<HARNESS_IGNORE_EXITCODE>
+
+Makes harness ignore the exit status of child processes when defined.
+
+=item C<HARNESS_NOTTY>
+
+When set to a true value, forces it to behave as though STDOUT were
+not a console. You may need to set this if you don't want harness to
+output more frequent progress messages using carriage returns. Some
+consoles may not handle carriage returns properly (which results in a
+somewhat messy output).
+
+=item C<HARNESS_PERL>
+
+Usually your tests will be run by C<$^X>, the currently-executing Perl.
+However, you may want to have it run by a different executable, such as
+a threading perl, or a different version.
+
+If you're using the F<prove> utility, you can use the C<--perl> switch.
+
+=item C<HARNESS_PERL_SWITCHES>
-The value of C<HARNESS_PERL_SWITCHES> will be prepended to the
-switches used to invoke perl on each test. For example, setting
-C<HARNESS_PERL_SWITCHES> to "-W" will run all tests with all
-warnings enabled.
+Its value will be prepended to the switches used to invoke perl on
+each test. For example, setting C<HARNESS_PERL_SWITCHES> to C<-W> will
+run all tests with all warnings enabled.
-If C<HARNESS_COLUMNS> is set, then this value will be used for the
-width of the terminal. If it is not set then it will default to
-C<COLUMNS>. If this is not set, it will default to 80. Note that users
-of Bourne-sh based shells will need to C<export COLUMNS> for this
-module to use that variable.
+=item C<HARNESS_VERBOSE>
-Harness sets C<HARNESS_ACTIVE> before executing the individual tests.
-This allows the tests to determine if they are being executed through the
-harness or by any other means.
+If true, Test::Harness will output the verbose results of running
+its tests. Setting C<$Test::Harness::verbose> will override this,
+or you can use the C<-v> switch in the F<prove> utility.
+

+
+=head1 EXAMPLE
+
+Here's how Test::Harness tests itself
+
+ $ cd ~/src/devel/Test-Harness
+ $ perl -Mblib -e 'use Test::Harness qw(&runtests $verbose);
+ $verbose=0; runtests @ARGV;' t/*.t
+ Using /home/schwern/src/devel/Test-Harness/blib
+ t/base..............ok
+ t/nonumbers.........ok
+ t/ok................ok
+ t/test-harness......ok
+ All tests successful.
+ Files=4, Tests=24, 2 wallclock secs ( 0.61 cusr + 0.41 csys = 1.02 CPU)
=head1 SEE ALSO
-L<Test> for writing test scripts and also L<Benchmark> for the
-underlying timing routines.
+The included F<prove> utility for running test scripts from the command line,
+L<Test> and L<Test::Simple> for writing test scripts, L<Benchmark> for
+the underlying timing routines, and L<Devel::Cover> for test coverage
+analysis.
+
+=head1 TODO
+
+Provide a way of running tests quietly (ie. no printing) for automated
+validation of tests. This will probably take the form of a version
+of runtests() which rather than printing its output returns raw data
+on the state of the tests. (Partially done in Test::Harness::Straps)
+
+Document the format.
+
+Fix HARNESS_COMPILE_TEST without breaking its core usage.
+
+Figure a way to report test names in the failure summary.
+
+Rework the test summary so long test names are not truncated as badly.
+(Partially done with new skip test styles)
+
+Add option for coverage analysis.
+
+Trap STDERR.
+
+Implement Straps total_results()
+
+Remember exit code
+
+Completely redo the print summary code.
+
+Implement Straps callbacks. (experimentally implemented)
+
+Straps->analyze_file() not taint clean, don't know if it can be
+
+Fix that damned VMS nit.
+
+HARNESS_TODOFAIL to display TODO failures
+
+Add a test for verbose.
+
+Change internal list of test results to a hash.
+
+Fix stats display when there's an overrun.
+
+Fix so perls with spaces in the filename work.
+
+Keeping whittling away at _run_all_tests()
+
+Clean up how the summary is printed. Get rid of those damned formats.

-Test::Harness uses $^X to determine the perl binary to run the tests
-with. Test scripts running via the shebang (C<#!>) line may not be
-portable because $^X is not consistent for shebang scripts across
-platforms. This is no problem when Test::Harness is run with an
-absolute path to the perl binary or when $^X can be found in the path.
