78
79=head1 NOTES
80
81=head2 .proverc
82
83If F<~/.proverc> or F<./.proverc> exist they will be read and any
84options they contain processed before the command line options. Options
85in F<.proverc> are specified in the same way as command line options:
86
87    # .proverc
88    --state=hot,fast,save
89    -j9
90
91Additional option files may be specified with the C<--rc> option.
92Default option file processing is disabled by the C<--norc> option.
93
94Under Windows and VMS the option file is named F<_proverc> rather than
95F<.proverc> and is sought only in the current directory.
96
97=head2 Reading from C<STDIN>
98
99If you have a list of tests (or URLs, or anything else you want to test) in a
100file, you can add them to your tests by using a '-':
101
102 prove - < my_list_of_things_to_test.txt
103
104See the C<README> in the C<examples> directory of this distribution.
105
106=head2 Default Test Directory
107
108If no files or directories are supplied, C<prove> looks for all files
109matching the pattern C<t/*.t>.
110
111=head2 Colored Test Output
112
113Colored test output using L<TAP::Formatter::Color> is the default, but
114if output is not to a terminal, color is disabled. You can override this by
115adding the C<--color> switch.
116
117Color support requires L<Term::ANSIColor> and, on windows platforms, also
118L<Win32::Console::ANSI>. If the necessary module(s) are not installed
119colored output will not be available.
120
121=head2 Exit Code
122
123If the tests fail C<prove> will exit with non-zero status.
124
125=head2 Arguments to Tests
126
127It is possible to supply arguments to tests. To do so separate them from
128prove's own arguments with the arisdottle, '::'. For example
129
130 prove -v t/mytest.t :: --url http://example.com
131
132would run F<t/mytest.t> with the options '--url http://example.com'.
133When running multiple tests they will each receive the same arguments.
134
135=head2 C<--exec>
136
137Normally you can just pass a list of Perl tests and the harness will know how
138to execute them.  However, if your tests are not written in Perl or if you
139want all tests invoked exactly the same way, use the C<-e>, or C<--exec>
140switch:
141
142 prove --exec '/usr/bin/ruby -w' t/
143 prove --exec '/usr/bin/perl -Tw -mstrict -Ilib' t/
144 prove --exec '/path/to/my/customer/exec'
145
146=head2 C<--merge>
147
148If you need to make sure your diagnostics are displayed in the correct
149order relative to test results you can use the C<--merge> option to
150merge the test scripts' STDERR into their STDOUT.
151
152This guarantees that STDOUT (where the test results appear) and STDERR
153(where the diagnostics appear) will stay in sync. The harness will
154display any diagnostics your tests emit on STDERR.
155
156Caveat: this is a bit of a kludge. In particular note that if anything
157that appears on STDERR looks like a test result the test harness will
158get confused. Use this option only if you understand the consequences
159and can live with the risk.
160
161=head2 C<--trap>
162
163The C<--trap> option will attempt to trap SIGINT (Ctrl-C) during a test
164run and display the test summary even if the run is interrupted
165
166=head2 C<--state>
167
168You can ask C<prove> to remember the state of previous test runs and
169select and/or order the tests to be run based on that saved state.
170
171The C<--state> switch requires an argument which must be a comma
172separated list of one or more of the following options.
173
174=over
175
176=item C<last>
177
178Run the same tests as the last time the state was saved. This makes it
179possible, for example, to recreate the ordering of a shuffled test.
180
181    # Run all tests in random order
182    $ prove -b --state=save --shuffle
183
184    # Run them again in the same order
185    $ prove -b --state=last
186
187=item C<failed>
188
189Run only the tests that failed on the last run.
190
191    # Run all tests
192    $ prove -b --state=save
193
194    # Run failures
195    $ prove -b --state=failed
196
197If you also specify the C<save> option newly passing tests will be
198excluded from subsequent runs.
199
200    # Repeat until no more failures
201    $ prove -b --state=failed,save
202
203=item C<passed>
204
205Run only the passed tests from last time. Useful to make sure that no
206new problems have been introduced.
207
208=item C<all>
209
210Run all tests in normal order. Multple options may be specified, so to
211run all tests with the failures from last time first:
212
213    $ prove -b --state=failed,all,save
214
215=item C<hot>
216
217Run the tests that most recently failed first. The last failure time of
218each test is stored. The C<hot> option causes tests to be run in most-recent-
219failure order.
220
221    $ prove -b --state=hot,save
222
223Tests that have never failed will not be selected. To run all tests with
224the most recently failed first use
225
226    $ prove -b --state=hot,all,save
227
228This combination of options may also be specified thus
229
230    $ prove -b --state=adrian
231
232=item C<todo>
233
234Run any tests with todos.
235
236=item C<slow>
237
238Run the tests in slowest to fastest order. This is useful in conjunction
239with the C<-j> parallel testing switch to ensure that your slowest tests
240start running first.
241
242    $ prove -b --state=slow -j9
243
244=item C<fast>
245
246Run test tests in fastest to slowest order.
247
248=item C<new>
249
250Run the tests in newest to oldest order based on the modification times
251of the test scripts.
252
253=item C<old>
254
255Run the tests in oldest to newest order.
256
257=item C<fresh>
258
259Run those test scripts that have been modified since the last test run.
260
261=item C<save>
262
263Save the state on exit. The state is stored in a file called F<.prove>
264(F<_prove> on Windows and VMS) in the current directory.
265
266=back
267
268The C<--state> switch may be used more than once.
269
270    $ prove -b --state=hot --state=all,save
271
272=head2 --rules
273
274The C<--rules> option is used to control which tests are run sequentially and
275which are run in parallel, if the C<--jobs> option is specified. The option may
276be specified multiple times, and the order matters.
277
278The most practical use is likely to specify that some tests are not
279"parallel-ready".  Since mentioning a file with --rules doesn't cause it to
280be selected to run as a test, you can "set and forget" some rules preferences in
281your .proverc file. Then you'll be able to take maximum advantage of the
282performance benefits of parallel testing, while some exceptions are still run
283in parallel.
284
285=head3 --rules examples
286
287    # All tests are allowed to run in parallel, except those starting with "p"
288    --rules='seq=t/p*.t' --rules='par=**'
289
290    # All tests must run in sequence except those starting with "p", which should be run parallel
291    --rules='par=t/p*.t'
292
293=head3 --rules resolution
294
295=over 4
296
297=item * By default, all tests are eligible to be run in parallel. Specifying any of your own rules removes this one.
298
299=item * "First match wins". The first rule that matches a test will be the one that applies.
300
301=item * Any test which does not match a rule will be run in sequence at the end of the run.
302
303=item * The existence of a rule does not imply selecting a test. You must still specify the tests to run.
304
305=item * Specifying a rule to allow tests to run in parallel does not make them run in parallel. You still need specify the number of parallel C<jobs> in your Harness object.
306
307=back
308
309=head3 --rules Glob-style pattern matching
310
311We implement our own glob-style pattern matching for --rules. Here are the
312supported patterns:
313
314    ** is any number of characters, including /, within a pathname
315    * is zero or more characters within a filename/directory name
316    ? is exactly one character within a filename/directory name
317    {foo,bar,baz} is any of foo, bar or baz.
318    \ is an escape character
319
320=head3 More advanced specifications for parallel vs sequence run rules
321
322If you need more advanced management of what runs in parallel vs in sequence, see
323the associated 'rules' documentation in L<TAP::Harness> and L<TAP::Parser::Scheduler>.
324If what's possible directly through C<prove> is not sufficient, you can write your own
325harness to access these features directly.
326
327=head2 @INC
328
329prove introduces a separation between "options passed to the perl which
330runs prove" and "options passed to the perl which runs tests"; this
331distinction is by design. Thus the perl which is running a test starts
332with the default C<@INC>. Additional library directories can be added
333via the C<PERL5LIB> environment variable, via -Ifoo in C<PERL5OPT> or
334via the C<-Ilib> option to F<prove>.
335
336=head2 Taint Mode
337
338Normally when a Perl program is run in taint mode the contents of the
339C<PERL5LIB> environment variable do not appear in C<@INC>.
340
341Because C<PERL5LIB> is often used during testing to add build
342directories to C<@INC> prove passes the names of any directories found
343in C<PERL5LIB> as -I switches. The net effect of this is that
344C<PERL5LIB> is honoured even when prove is run in taint mode.
345
346
347=head1 FORMATTERS
348
349You can load a custom L<TAP::Parser::Formatter>:
350
351  prove --formatter MyFormatter
352
353=head1 SOURCE HANDLERS
354
355You can load custom L<TAP::Parser::SourceHandler>s, to change the way the
356parser interprets particular I<sources> of TAP.
357
358  prove --source MyHandler --source YetAnother t
359
360If you want to provide config to the source you can use:
361
362  prove --source MyCustom \
363        --source Perl --perl-option 'foo=bar baz' --perl-option avg=0.278 \
364        --source File --file-option extensions=.txt --file-option extensions=.tmp t
365        --source pgTAP --pgtap-option pset=format=html --pgtap-option pset=border=2
366
367Each C<--$source-option> option must specify a key/value pair separated by an
368C<=>. If an option can take multiple values, just specify it multiple times,
369as with the C<extensions=> examples above. If the option should be a hash
370reference, specify the value as a second pair separated by a C<=>, as in the
371C<pset=> examples above (escape C<=> with a backslash).
372
373All C<--sources> are combined into a hash, and passed to L<TAP::Harness/new>'s
374C<sources> parameter.
375
376See L<TAP::Parser::IteratorFactory> for more details on how configuration is
377passed to I<SourceHandlers>.
378
379=head1 PLUGINS
380
381Plugins can be loaded using the C<< -PI<plugin> >> syntax, eg:
382
383  prove -PMyPlugin
384
385This will search for a module named C<App::Prove::Plugin::MyPlugin>, or failing
386that, C<MyPlugin>.  If the plugin can't be found, C<prove> will complain & exit.
387
388You can pass arguments to your plugin by appending C<=arg1,arg2,etc> to the
389plugin name:
390
391  prove -PMyPlugin=fou,du,fafa
392
393Please check individual plugin documentation for more details.
