53 Test::Harness - run perl standard test scripts with statistics
59 runtests(@test_files);
63 B<STOP!> If all you want to do is write a test script, consider using
64 Test::Simple. Otherwise, read on.
66 (By using the Test module, you can write test scripts without
67 knowing the exact output this module expects. However, if you need to
68 know the specifics, read on!)
70 Perl test scripts print to standard output C<"ok N"> for each single
71 test, where C<N> is an increasing sequence of integers. The first line
72 output by a standard test script is C<"1..M"> with C<M> being the
73 number of tests that should be run within the test
74 script. Test::Harness::runtests(@tests) runs all the testscripts
75 named as arguments and checks standard output for the expected
78 After all tests have been performed, runtests() prints some
79 performance statistics that are computed by the Benchmark module.
81 =head2 The test script output
83 The following explains how Test::Harness interprets the output of your
90 This header tells how many tests there will be. For example, C<1..10>
91 means you plan on running 10 tests. This is a safeguard in case your
92 test dies quietly in the middle of its run.
94 It should be the first non-comment line output by your test program.
96 In certain instances, you may not know how many tests you will
97 ultimately be running. In this case, it is permitted for the 1..M
98 header to appear as the B<last> line output by your test (again, it
99 can be followed by further comments).
101 Under B<no> circumstances should 1..M appear in the middle of your
102 output or more than once.
105 =item B<'ok', 'not ok'. Ok?>
107 Any output from the testscript to standard error is ignored and
108 bypassed, thus will be seen by the user. Lines written to standard
109 output containing C</^(not\s+)?ok\b/> are interpreted as feedback for
110 runtests(). All other lines are discarded.
112 C</^not ok/> indicates a failed test. C</^ok/> is a successful test.
115 =item B<test numbers>
117 Perl normally expects the 'ok' or 'not ok' to be followed by a test
118 number. It is tolerated if the test numbers after 'ok' are
119 omitted. In this case Test::Harness maintains temporarily its own
120 counter until the script supplies test numbers again. So the following
135 Failed 3/6 tests, 50.00% okay
139 Anything after the test number but before the # is considered to be
140 the name of the test.
142 ok 42 this is the name of the test
144 Currently, Test::Harness does nothing with this information.
146 =item B<Skipping tests>
148 If the standard output line contains the substring C< # Skip> (with
149 variations in spacing and case) after C<ok> or C<ok NUMBER>, it is
150 counted as a skipped test. If the whole testscript succeeds, the
151 count of skipped tests is included in the generated output.
152 C<Test::Harness> reports the text after C< # Skip\S*\s+> as a reason
155 ok 23 # skip Insufficient flogiston pressure.
157 Similarly, one can include a similar explanation in a C<1..0> line
158 emitted if the test script is skipped completely:
160 1..0 # Skipped: no leverage found
164 If the standard output line contains the substring C< # TODO> after
165 C<not ok> or C<not ok NUMBER>, it is counted as a todo test. The text
166 afterwards is the thing that has to be done before this test will
169 not ok 13 # TODO harness the power of the atom
173 Alternatively, you can specify a list of what tests are todo as part
178 This only works if the header appears at the beginning of the test.
180 This style is B<deprecated>.
184 These tests represent a feature to be implemented or a bug to be fixed
185 and act as something of an executable "thing to do" list. They are
186 B<not> expected to succeed. Should a todo test begin succeeding,
187 Test::Harness will report it as a bonus. This indicates that whatever
188 you were supposed to do has been done and you should promote this to a
193 As an emergency measure, a test script can decide that further tests
194 are useless (e.g. missing dependencies) and testing should stop
195 immediately. In that case the test script prints the magic words
199 to standard output. Any message after these words will be displayed by
200 C<Test::Harness> as the reason why testing is stopped.
204 Additional comments may be put into the testing output on their own
205 lines. Comment lines should begin with a '#', Test::Harness will
209 # Life is good, the sun is shining, RAM is cheap.
211 # got 'Bush' expected 'Gore'
213 =item B<Anything else>
215 Any other output Test::Harness sees it will silently ignore B<BUT WE
216 PLAN TO CHANGE THIS!> If you wish to place additional output in your
217 test script, please use a comment.
224 Test::Harness will honor the C<-T> in the #! line on your test files. So
225 if you begin a test with:
229 the test will be run with taint mode on.
232 =head2 Configuration variables.
234 These variables can be used to configure the behavior of
235 Test::Harness. They are exported on request.
239 =item B<$Test::Harness::verbose>
241 The global variable $Test::Harness::verbose is exportable and can be
242 used to let runtests() display the standard output of the script
243 without altering the behavior otherwise.
245 =item B<$Test::Harness::switches>
247 The global variable $Test::Harness::switches is exportable and can be
248 used to set perl command line options used for running the test
249 script(s). The default value is C<-w>.
256 It will happen, your tests will fail. After you mop up your ego, you
257 can begin examining the summary report:
259 t/base..............ok
260 t/nonumbers.........ok
261 t/ok................ok
262 t/test-harness......ok
263 t/waterloo..........dubious

270 Failed 1/5 test scripts, 80.00% okay. 10/44 subtests failed, 77.27% okay.
272 Everything passed but t/waterloo.t. It failed 10 of 20 tests and
273 exited with non-zero status indicating something dubious happened.
275 The columns in the summary report mean:
281 The test file which failed.
285 If the test exited with non-zero, this is its exit status.
289 The wait status of the test I<umm, I need a better explanation here>.
293 Total number of tests expected to run.
297 Number which failed, either from "not ok" or because they never ran.
301 Percentage of the total tests which failed.
303 =item B<List of Failed>
305 A list of the tests which failed. Successive failures may be
306 abbreviated (ie. 15-20 to indicate that tests 15, 16, 17, 18, 19 and
314 Test::Harness currently only has one function, here it is.
320 my $allok = runtests(@test_files);
322 This runs all the given @test_files and divines whether they passed
323 or failed based on their output to STDOUT (details above). It prints
324 out each individual test which failed along with a summary report and
325 a how long it all took.
327 It returns true if everything was ok. Otherwise it will die() with
328 one of the messages in the DIAGNOSTICS section.
331 This is just _run_all_tests() plus _show_results()
340 my($tot, $failedtests) = _run_all_tests(@tests);

343 my $ok = _all_ok($tot);
345 assert(($ok xor keys %$failedtests),
346 q{ok status jives with $failedtests});
355 my $ok = _all_ok(\%tot);
357 Tells you if this test run is overall successful or not.
364 return $tot->{bad} == 0 && ($tot->{max} || $tot->{skipped}) ? 1 : 0;
369 my @files = _globdir $dir;
371 Returns all the files in a directory. This is shorthand for backwards
372 compatibility on systems where glob() doesn't work right.
378 my @f = readdir DIRH;
384 =item B<_run_all_tests>
386 my($total, $failed) = _run_all_tests(@test_files);
388 Runs all the given @test_files (as runtests()) but does it quietly (no
389 report). $total is a hash ref summary of all the tests run. Its keys
392 bonus Number of individual todo tests unexpectedly passed
393 max Number of individual tests ran
394 ok Number of individual tests passed

398 files Number of test files ran
399 good Number of test files passed
400 bad Number of test files failed
401 tests Number of test files originally given
402 skipped Number of test files skipped
404 If $total->{bad} == 0 and $total->{max} > 0, you've got a successful
407 $failed is a hash ref of all the test scripts which failed. Each key
408 is the name of a test script, each value is another hash representing
409 how that script failed. Its keys are these:
411 name Name of the test which failed
412 estat Script's exit value
413 wstat Script's wait status
414 max Number of individual tests
415 failed Number which failed
416 percent Percentage of tests which failed
417 canon List of tests which failed (as string).
419 Needless to say, $failed should be empty if everything passed.

959 If not all tests were successful, the script dies with one of the
962 =item C<FAILED--Further testing stopped: %s>
964 If a single subtest decides that further testing will not make sense,
965 the script dies with this message.
973 =item C<HARNESS_ACTIVE>
975 Harness sets this before executing the individual tests. This allows
976 the tests to determine if they are being executed through the harness
977 or by any other means.
979 =item C<HARNESS_COLUMNS>
981 This value will be used for the width of the terminal. If it is not
982 set then it will default to C<COLUMNS>. If this is not set, it will
983 default to 80. Note that users of Bourne-sh based shells will need to
984 C<export COLUMNS> for this module to use that variable.
986 =item C<HARNESS_COMPILE_TEST>
988 When true it will make harness attempt to compile the test using
989 C<perlcc> before running it.
991 B<NOTE> This currently only works when sitting in the perl source
994 =item C<HARNESS_FILELEAK_IN_DIR>
996 When set to the name of a directory, harness will check after each
997 test whether new files appeared in that directory, and report them as
999 LEAKED FILES: scr.tmp 0 my.db
1001 If relative, directory name is with respect to the current directory at
1002 the moment runtests() was called. Putting absolute path into
1003 C<HARNESS_FILELEAK_IN_DIR> may give more predictable results.
1005 =item C<HARNESS_IGNORE_EXITCODE>
1007 Makes harness ignore the exit status of child processes when defined.
1009 =item C<HARNESS_NOTTY>
1011 When set to a true value, forces it to behave as though STDOUT were
1012 not a console. You may need to set this if you don't want harness to
1013 output more frequent progress messages using carriage returns. Some
1014 consoles may not handle carriage returns properly (which results in a
1015 somewhat messy output).
1017 =item C<HARNESS_PERL_SWITCHES>
1019 Its value will be prepended to the switches used to invoke perl on
1020 each test. For example, setting C<HARNESS_PERL_SWITCHES> to C<-W> will
1021 run all tests with all warnings enabled.
1023 =item C<HARNESS_VERBOSE>
1025 If true, Test::Harness will output the verbose results of running
1026 its tests. Setting $Test::Harness::verbose will override this.
1032 Here's how Test::Harness tests itself
1034 $ cd ~/src/devel/Test-Harness
1035 $ perl -Mblib -e 'use Test::Harness qw(&runtests $verbose);
1036 $verbose=0; runtests @ARGV;' t/*.t
1037 Using /home/schwern/src/devel/Test-Harness/blib
1038 t/base..............ok
1039 t/nonumbers.........ok
1040 t/ok................ok
1041 t/test-harness......ok
1042 All tests successful.
1043 Files=4, Tests=24, 2 wallclock secs ( 0.61 cusr + 0.41 csys = 1.02 CPU)
1047 L<Test> and L<Test::Simple> for writing test scripts, L<Benchmark> for
1048 the underlying timing routines, L<Devel::CoreStack> to generate core
1049 dumps from failed tests and L<Devel::Cover> for test coverage
1054 Either Tim Bunce or Andreas Koenig, we don't know. What we know for
1055 sure is, that it was inspired by Larry Wall's TEST script that came
1056 with perl distributions for ages. Numerous anonymous contributors
1057 exist. Andreas Koenig held the torch for many years.
1059 Current maintainer is Michael G Schwern E<lt>schwern@pobox.comE<gt>
1063 Provide a way of running tests quietly (ie. no printing) for automated
1064 validation of tests. This will probably take the form of a version
1065 of runtests() which rather than printing its output returns raw data
1066 on the state of the tests. (Partially done in Test::Harness::Straps)
1068 Fix HARNESS_COMPILE_TEST without breaking its core usage.
1070 Figure a way to report test names in the failure summary.
1072 Rework the test summary so long test names are not truncated as badly.
1073 (Partially done with new skip test styles)
1075 Deal with VMS's "not \nok 4\n" mistake.
1077 Add option for coverage analysis.
1080 Keeping whittling away at _run_all_tests()
1083 Clean up how the summary is printed. Get rid of those damned formats.
1087 HARNESS_COMPILE_TEST currently assumes it's run from the Perl source
