1 Revision history for Perl extension Test::Harness
3 2.62 Thu Jun 8 14:11:57 CDT 2006
5 * Restored the behavior of dying if any subtests failed. This is a
6 pretty crucial bug that I should have fixed long ago. Not having this
7 means that CPANPLUS will install modules even if their tests fail. :-(
9 2.60 Wed May 24 14:48:44 CDT 2006
11 * Fixed the headers in the summary failure table.
13 2.58 Sat May 13 22:53:53 CDT 2006
14 No changes. Released to the world with a non-beta number.
16 2.57_06 Sun Apr 23 00:55:43 CDT 2006
17 [THINGS THAT MIGHT BREAK YOUR CODE]
18 * Anything that displays a percentage of tests passed has been
19 removed. Output at the end of failing runs is now different.
22 * Fixed the TODO-passing patch from 2.57_05.
25 * The unnecessary display of percentages of tests passing and failing
26 have been removed. Tests are not a percentage game.
28 * Caches the results of _default_inc(), which is expensive because
29 of shelling out to get the pathnames. Benchmarking was showing that
30 15% of Test::Harness's time was spent in this function. For test
31 suites with many test files, this can be significant. With this
32 speedup, the "make test" for the Perl core speeds up 2.5%.
33 Thanks to Nicholas Clark for finding this.
36 * Fixed HARNESS_PERL_SWITCHES typo. Thanks, Andreas Koenig.
38 * Added docs on HARNESS_TIMER and --timer. Thanks, Mike O'Regan.
40 2.57_05 Wed Apr 19 00:31:10 CDT 2006
42 * Now shows details of the tests that unexpectedly pass, instead of
43 just giving a number. Thanks, demerphq!
46 * Fixed globbing to work under Perls before 5.6.0. Before Perl 5.6.0,
47 prove just uses the internal glob() function.
49 2.57_04 Mon Apr 17 13:35:10 CDT 2006
51 * prove's globbing is now done with File::Glob::bsd_glob().
52 Otherwise, "prove c:\program files\svk\t\*" fails because glob()
53 considers it to be two patterns, splitting on whitespace. Thanks to
57 * Added information about other TAP implementations in other languages.
61 [THINGS THAT MAY BREAK YOUR CODE]
62 * Internal functions _run_all_tests() and _show_results() no longer
63 exist. You shouldn't have been using them anyway since they're
64 prepended with underscores.
67 * Added the ability to send test output to a filehandle of
68 one's choosing. Two internal functions are now exposed:
69 execute_tests() and get_results() (formerly _run_all_tests() and
70 _show_results()). This should allow CPANPLUS to work properly
71 with Module::Build. Thanks to Ken Williams.
74 * Hid the documentation for the private methods in Test::Harness::Straps.
76 2.57_02 Fri Dec 30 23:51:17 CST 2005
77 [THINGS THAT MAY BREAK YOUR CODE]
78 * prove's --ext option has been removed. I'm betting that nobody used it.
81 * prove can now take -w and -W switches, analogous to those in perl.
82 This means that "prove -wlb t/*.t" is exactly the same as "make test".
84 * Started a Test::Harness::Util module for code that may be reused
85 by other Harness-using modules.
88 * The t/prove*.t tests now use $^X to call prove. Thanks to Yves Orton.
89 * Test::Harness::Straps no longer uses Win32::GetShortPathName().
92 2.57_01 Mon Dec 26 01:39:07 CST 2005
94 * Removed code and docs mentioning HARNESS_IGNORE_EXITCODE, which
98 * If we have hi-res timings, then they're shown in integer
99 milliseconds, rather than fractional seconds.
101 * Added the --perl switch to prove.
104 * Added links to CPAN support sites.
106 2.56 Wed Sep 28 16:04:00 CDT 2005
108 * Incorporate bleadperl patch to fix Test::Harness on VMS.
110 2.54 Wed Sep 28 09:52:19 CDT 2005
112 * Test counts were wrong, so wouldn't install on Perls < 5.8.0.
114 2.53_02 Thu Aug 25 21:37:01 CDT 2005
116 * File order in prove is now sorted within the directory. It's not
117 the sorting that's important as much as the deterministic results.
118 Thanks to Adam Kennedy and Casey West for pointing this out,
119 independently of each other, with 12 hours of the other.
122 * Fix calls to podusage() to not use the DATA typeglob. Thanks sungo.
124 2.53_01 Sun Jul 10 10:45:27 CDT 2005
126 * If we go over 100,000 tests, it used to print out a warning for
127 every test over 100,000. Now, we stop after the first. Thanks to
128 Sebastien Aperghis-Tramoni.
130 2.52 Sun Jun 26 23:05:19 CDT 2005
135 * The Test::Harness timer is now off by default. Set HARNESS_TIMER
136 true if you want it. Added --timer flag to prove.
140 * Call CORE::time() to figure out if we should print when we're
141 printing once per second. Otherwise, we're using Time::HiRes'
142 version of it. Thanks, Nicholas Clark.
144 2.50 Tue Jun 21 14:32:12 CDT 2005
146 * Added some includes in t/strap-analyze.t to make Cygwin happy.
148 2.49_02 Tue Jun 21 09:54:44 CDT 2005
150 * Added some includes in t/test_harness.t to make Cygwin happy.
152 2.49_01 Fri Jun 10 15:37:31 CDT 2005
154 * Now shows elapsed time in 1000ths of a second if Time::HiRes
158 * Test::Harness::Iterator didn't have a 1; at the end. Thanks to
159 Steve Peters for finding it.
161 2.48 Fri Apr 22 22:41:46 CDT 2005
162 Released after weeks of non-complaint.
164 2.47_03 Wed Mar 2 16:52:55 CST 2005
165 [THINGS THAT MIGHT BREAK YOUR CODE]
166 * Test::Harness now requires Perl 5.005_03 or above.
169 * Fixed incorrect "confused by tests in wrong order" error in 2.47_02.
171 2.47_02 Tue Mar 1 23:15:47 CST 2005
172 [THINGS THAT MIGHT BREAK YOUR CODE]
173 * Test directives for skip tests used to be anything that matches
174 /^skip/i, like the word "skipped", but now it must match
178 * T::H now sets environment variable HARNESS_VERSION, in case a test
179 program wants to know what version of T::H it's running under.
181 2.47_01 Mon Feb 21 01:14:13 CST 2005
183 * Fixed a problem submitted by Craig Berry:
185 Several of the Test::Harness tests now fail on VMS with the
188 Can't find string terminator "]" anywhere before EOF at -e line 1.
190 The problem is that when a command is piped to the shell and that
191 command has a newline character embedded in it, the part after
192 the newline is invisible to the shell. The patch below corrects
193 that by escaping the newline so it is not subject to variable
194 interpolation until it gets to the child's Perl one-liner.
197 * Test::Harness::Straps now has diagnostic gathering without changing
198 how tests are run. It also adds these messages by default.
199 Note that the new method, _is_diagnostic(), is for internal
200 use only. It may change soon. Thanks to chromatic.
203 * Expanded Test::Harness::TAP.pod, and added examples.
205 * Fixed a crucial documentation typo in Test::Harness::Straps.
207 2.46 Thu Jan 20 11:50:59 CST 2005
210 2.45_02 Fri Dec 31 14:57:33 CST 2004
212 * Turns off buffering on both STDERR and STDOUT, so that the two
213 output handles don't get out of sync with each other. Thanks to
216 * No longer requires, or supports, the HARNESS_OK_SLOW environment
217 variable. Test counts are only updated once per second, which
218 used to require having HARNESS_OK_SLOW set.
220 2.45_01 Fri Dec 17 22:39:17 CST 2004
221 [THINGS THAT MIGHT BREAK YOUR CODE]
222 * Test::Harness now requires Perl 5.004_05.
224 * We no longer try to print a stack if a coredump is detected.
227 * Reverted Test::Harness::Iterator::next()'s use of readline, since
228 it fails under Perl 5.5.4.
230 * We no longer try to print a stack if a coredump is detected.
231 This means that the external problems we've had with wait.ph
232 now disappear. This resolves a number of problems that various
233 Linux distros have, and closes a couple of RT tickets like #2729
237 * Added Test::Harness->strap() method to access the internal strap.
240 * Obfuscated the rt.cpan.org email address. The damage is already
241 done, but at least we'll have it hidden going forward.
243 2.44 Tue Nov 30 18:38:17 CST 2004
245 * De-anonymized the callbacks and handlers in Test::Harness, mostly
246 so I can profile better.
248 * Checks _is_header() only if _is_line() fails first. No point
249 in checking every line of the input for something that can only
252 * Inline the _detailize() function, which was getting called once
253 per line of input. Reduced execution time about 5-7%.
255 * Removed unnecessary temporary variables in Test::Harness::Straps
256 and in Test::Harness::Iterator.
258 2.43_02 Thu Nov 25 00:20:36 CST 2004
260 * Added more debug output if $Test::Harness::Debug is on.
263 * Test::Harness now removes default paths from the paths that it
264 sets in PERL5LIB. This fixes RT #5649. Thanks, Schwern.
266 [THINGS THAT MIGHT BREAK YOUR CODE]
267 * Test::Harness::Straps' constructor no longer will work as an
268 object method. You can't say $strap->new any more, but that's
269 OK because you never really wanted to anyway.
273 * Added workaround for local $ENV{} bug on Cygwin to
274 t/prove-switches.t. See the following RT tickets for details.
276 https://rt.cpan.org/Ticket/Display.html?id=6452
277 http://rt.perl.org/rt3/Ticket/Display.html?id=30952
280 2.42 Wed Apr 28 22:13:11 CDT 2004
282 * prove -v now sets TEST_VERBOSE in case your tests rely on them.
283 * prove globs the command line, since Win32's shell doesn't.
286 * Cross-platform test fixes on t/prove-globbing.t
289 2.40 Tue Dec 30 20:38:59 CST 2003
291 * Test::Harness::Straps should now properly quote on VMS.
294 * prove now takes a -l option to add lib/ to @INC. Now when you're
295 building a module, you don't have to do a make before you run
296 the prove. Thanks to David Wheeler for the idea.
299 * Internal functions corestatus() and canonfailed() prepended with
300 underscores, to indicate such.
302 * Gratuitous text-only changes in Test::Harness::Iterator.
304 * All tests now do their use_ok() in a BEGIN block. Some of the
305 use_ok() calls were too much of a hassle to put into a BEGIN block,
306 so I changed them to regular use calls.
309 2.38 Mon Nov 24 22:36:18 CST 2003
310 Released. See changes below.
312 2.37_03 Tue Nov 18 23:51:38 CST 2003
314 * prove -V now shows the Perl version being used.
315 * Now there's a HARNESS_DEBUG flag that shows diagnostics as the
316 harness runs the tests. This is different from HARNESS_VERBOSE,
317 which shows test output, but not information about the harness
319 * Added _command_line() to the Strap API.
322 * Bad interaction with Module::Build: The strap was only checking
323 $ENV{HARNESS_PERL_SWITCHES} for definedness, but not emptiness.
324 It now also strips any leading or trailing whitesapce from the
326 * Test::Harness and prove only quote those parms that actually need
327 to be quoted: Have some whitespace and aren't already quoted.
329 2.36 Fri Nov 14 09:24:44 CST 2003
331 * t/prove-includes.t properly ignores PROVE_SWITCHES that you may
334 2.35_02 Thu Nov 13 09:57:36 CST 2003
336 * prove's --blib now works just like the blib pragma.
338 2.35_01 Wed Nov 12 23:08:45 CST 2003
340 * Fixed taint-handling and path preservation under MacOS. Thanks to
341 Schwern for the patch and the tests.
343 * Preserves case of -t or -T in the shebang line of the test.
346 * Added -t to prove analogous to Perl's -t. Removed the --taint
349 * prove can take default options from the PROVE_SWITCHES variable.
351 * Added HARNESS_PERL to allow you to specify the Perl interpreter
354 * prove's --perl switch sets the HARNESS_PERL on the fly for you.
356 * Quotes the switches and filename in the subprogram. This helps
357 with filenames with spaces that are subject to shell mangling.
360 2.34 Sat Nov 8 22:09:15 CST 2003
362 * Allowed prove to run on Perl versions < 5.6.0.
365 * Command-line switches to prove may now be stacked.
366 * Added check for proper Pod::Usage version.
367 * "make clean" does a better job of cleaning up after itself.
370 2.32 Fri Nov 7 09:41:21 CST 2003
371 Test::Harness now includes a powerful development tool to help
372 programmers work with automated tests. The prove utility runs
373 test files against the harness, like a "make test", but with many
376 * prove is designed as a development tool
377 Perl users typically run the test harness through a makefile via
378 "make test". That's fine for module distributions, but it's
379 suboptimal for a test/code/debug development cycle.
382 prove lets your run against only the files you want to check.
383 Running "prove t/live/ t/master.t" checks every *.t in t/live, plus
386 * prove has an easy verbose mode
387 To get full test program output from "make test", you must set
388 "HARNESS_VERBOSE" in the environment. prove has a "-v" option.
390 * prove can run under taint mode
391 prove's "-T" runs your tests under "perl -T".
393 * prove can shuffle tests
394 You can use prove's "--shuffle" option to try to excite problems
395 that don't show up when tests are run in the same order every time.
397 * Not everything is a module
398 More and more users are using Perl's testing tools outside the
399 context of a module distribution, and may not even use a makefile at
402 Prove requires Pod::Usage, which is standard after Perl 5.004.
404 I'm very excited about prove, and hope that developers will begin
405 adopting it to their coding cycles. I welcome your comments at
408 There are also some minor bug fixes in Test::Harness itself, listed
409 below in the 2.31_* notes.
412 2.31_05 Thu Nov 6 14:56:22 CST 2003
414 - If a MacPerl script had a shebang with -T, the -T wouldn't get
416 - Removed the -T on three *.t files, which didn't need them, and
417 which were causing problems.
418 - Conditionally installs bin/prove, depending on whether Pod::Usage
419 is available, which prove needs.
420 - Removed old leftover code from Makefile.PL.
422 2.31_04 Mon Nov 3 23:36:06 CST 2003
423 Minor tweaks here and there, almost ready to release.
425 2.31_03 Mon Nov 3 08:50:36 CST 2003
427 - prove is almost feature-complete. Removed the handling of
428 --exclude for excluding certain tests. It may go back in the
430 - prove -d is now debug. Dry is prove -D.
432 2.31_02 Fri Oct 31 23:46:03 CST 2003
434 - Added many more switches to prove: -d for dry run, and -b for
438 - T:H:Straps now recognizes MSWin32 in $^0.
439 - RT#3811: Could do regex matching on garbage in _is_test().
441 - RT#3827: Strips backslashes from and normalizes @INC entries
442 for Win32. Fixed by Yves Orton.
445 - Added $self->{_is_macos} to the T:H:Strap object.
446 - t/test-harness.t sorts its test results, rather than relying on
451 - Added "prove" script to run a test or set of tests through the
452 harness. Thanks to Curtis Poe for the foundation.
455 - Fixed POD problem in Test::Harness::Assert
457 2.30 Thu Aug 14 20:04:00 CDT 2003
458 No functional changes in this version. It's only to make some doc
459 tweaks, and bump up the version number in T:H:Straps.
462 - Changed Schwern to Andy as the maintainer.
463 - Incorporated the TODO file into Harness.pm proper.
464 - Cleaned up formatting in Test::Harness::Straps.
466 2.29 Wed Jul 17 14:08:00 CDT 2003
469 2.28_91 Sun Jul 13 00:10:00 CDT 2003
471 - Added support for HARNESS_OK_SLOW. This will make a significant
472 speedup for slower connections.
473 - Folded in some changes from bleadperl that spiff up the
477 - Added some isa_ok() checks to the tests.
478 - All Test::Harness* modules are used by use_ok()
479 - Fixed the prototype for the canonfailed() function, not that
480 it matters since it's never called without parens.
482 2.28_90 Sat Jul 05 20:21:00 CDT 2003
484 - Now, when you run a test harnessed, the numbers don't fly by one
485 at a time, one update per second. This significantly speeds
486 up the run time for running thousands of tests. *COUGH*
487 Regexp::Common *COUGH*
489 2.28 Thu Apr 24 14:39:00 CDT 2003
490 - No functional changes.
492 2.27_05 Mon Apr 21 15:55:00 CDT 2003
493 - No functional changes.
494 - Fixed circular depency in the test suite. Thanks, Rob Brown.
496 2.27_04 Sat Apr 12 21:42:00 CDT 2003
497 - Added test for $Test::Harness::Switches patch below.
499 2.27_03 Thu Apr 03 10:47:00 CDT 2003
500 - Fixed straps not respecting $Test::Harness::Switches. Thanks
501 to Miyagawa for the patch.
502 - Added t/pod.t to test POD validity.
504 2.27_02 Mon Mar 24 13:17:00 CDT 2003
505 2.27_01 Sun Mar 23 19:46:00 CDT 2003
506 - Handed over to Andy Lester for further maintenance.
507 - Fixed when the path to perl contains spaces on Windows
508 * Stas Bekman noticed that tests with no output at all were
509 interpreted as passing
510 - MacPerl test tweak for busted exit codes (bleadperl 17345)
511 - Abigail and Nick Clark both hit the 100000 "huge test that will
512 suck up all your memory" limit with legit tests. Made the check
513 smarter to allow large, planned tests to work.
514 - Partial fix of stats display when a test fails only because there's
516 - Made wait.ph and WCOREDUMP anti-vommit protection more robust in
517 cases where wait.ph loads but WCOREDUMP() pukes when run.
519 - Ilya noticed the per test skip reason was accumlating between tests.
521 2.26 Wed Jun 19 16:58:02 EDT 2002
522 - Workaround for MacPerl's lack of a working putenv. It will never
523 see the PERL5LIB environment variable (perl@16942).
525 2.25 Sun Jun 16 03:00:33 EDT 2002
526 - $Strap is now a global to allow Test::Harness::Straps
528 - Little spelling nit in a diagnostic.
529 - Chris Richmond noted that the runtests() docs were wrong. It will
530 die, not return false, when any tests fail. This is silly, but
531 historically necessary for 'make test'. Docs corrected.
532 - MacPerl test fixes from Pudge. (mutation of bleadperl@16989)
533 - Undef warning introduced in 2.24 on skipped tests with no reasons
535 * Test::Harness now depends on File::Spec
537 2.24 Wed May 29 19:02:18 EDT 2002
538 * Nikola Knezevic found a bug when tests are completely skipped
539 but no reason is given it was considered a failure.
540 * Made Test::Harness::Straps->analyze_file & Test::Harness a bit
541 more graceful when the test doesn't exist.
543 2.23 Wed May 22 12:59:47 EDT 2002
544 - reason for all skip wasn't being displayed. Broken in 2.20.
545 - Changed the wait status tests to conform with POSIX standards.
546 - Quieted some SYSTEM$ABORT noise leaking out from dying test tests
549 2.22 Fri May 17 19:01:35 EDT 2002
550 - Fixed parsing of #!/usr/bin/perl-current to not see a -t.
552 - Fixed exit codes on MPE/iX
554 2.21 Mon May 6 00:43:22 EDT 2002
555 - removed a bunch of dead code left over after 2.20's gutting.
556 - The fix for the $^X "bug" added in 2.02 has been removed. It
557 caused more trouble than the old bug (I'd never seen a problem
559 - 2.20 broke $verbose
561 2.20 Sat May 4 22:31:20 EDT 2002
562 * An almost complete conversion of the Test::Harness test parsing
563 to use Test::Harness::Straps.
565 2.04 Tue Apr 30 00:54:49 EDT 2002
566 * Changing the output format of skips
567 - Taking into account VMS's special exit codes in the tests.
569 2.03 Thu Apr 25 01:01:34 EDT 2002
570 * $^X fix made safer.
571 - Noise from loading wait.ph to analyze core files supressed
572 - MJD found a situation where a test could run Test::Harness
573 out of memory. Protecting against that specific case.
574 - Made the 1..M docs a bit clearer.
575 - Fixed TODO tests so Test::Harness does not display a NOK for
577 - Test::Harness::Straps->analyze_file() docs were not clear as to
580 2.02 Thu Mar 14 18:06:04 EST 2002
581 * Ken Williams fixed the long standing $^X bug.
582 * Added HARNESS_VERBOSE
583 * Fixed a bug where Test::Harness::Straps was considering a test that
584 is ok but died as passing.
585 - Added the exit and wait codes of the test to the
586 analyze_file() results.
588 2.01 Thu Dec 27 18:54:36 EST 2001
589 * Added 'passing' to the results to tell you if the test passed
590 * Added Test::Harness::Straps example (examples/mini_harness.plx)
591 * Header-at-end tests were being interpreted as failing sometimes
592 - The 'skip_all' results from analyze* was not being set
593 - analyze_fh() and analyze_file() now work more efficiently, reading
594 line-by-line instead of slurping as before.
596 2.00 Sun Dec 23 19:13:57 EST 2001
597 - Fixed a warning on VMS.
598 - Removed a little unnecessary code from analyze_file()
599 - Made sure filehandles are getting closed
600 - analyze() now considers "not \nok" to be a failure (VMSism)
601 but Test::Harness still doesn't.
603 2.00_05 Mon Dec 17 22:08:02 EST 2001
604 * Wasn't filtering @INC properly when a test is run with -T, caused the
605 command line to be too long on VMS. VMS should be 100% now.
606 - Little bug in the skip 'various reasons' logic.
607 - Minor POD nit in 5.004_04
608 - Little speling mistak
610 2.00_04 Sun Dec 16 00:33:32 EST 2001
611 * Major Test::Harness::Straps doc bug.
613 2.00_03 Sat Dec 15 23:52:17 EST 2001
614 * First release candidate
615 * 'summary' is now 'details'
616 * Test #1 is now element 0 on the details array. It works out better
618 * analyze_file() is more portable, but no longer taint clean
619 * analyze_file() properly preserves @INC and handles -T switches

684 - Gisle sent me a documentation patch that showed me, that the
685 unless(/^#/) is unnessessary. Applied the patch and deleted the block

687 not match /^1\.\.([0-9]+)/ or /^(not\s+)?ok\b/.
