77 =head1 NOTES
79 =head2 .proverc
81 If F<~/.proverc> or F<./.proverc> exist they will be read and any
82 options they contain processed before the command line options. Options
83 in F<.proverc> are specified in the same way as command line options:
85 # .proverc
86 --state=hot,fast,save
87 -j9
89 Additional option files may be specified with the C<--rc> option.
90 Default option file processing is disabled by the C<--norc> option.
92 Under Windows and VMS the option file is named F<_proverc> rather than
93 F<.proverc> and is sought only in the current directory.
95 =head2 Reading from C<STDIN>
97 If you have a list of tests (or URLs, or anything else you want to test) in a
98 file, you can add them to your tests by using a '-':
100 prove - < my_list_of_things_to_test.txt
102 See the C<README> in the C<examples> directory of this distribution.
104 =head2 Default Test Directory
106 If no files or directories are supplied, C<prove> looks for all files
107 matching the pattern C<t/*.t>.
109 =head2 Colored Test Output
111 Colored test output is the default, but if output is not to a
112 terminal, color is disabled. You can override this by adding the
113 C<--color> switch.
115 Color support requires L<Term::ANSIColor> on Unix-like platforms and
116 L<Win32::Console> windows. If the necessary module is not installed
117 colored output will not be available.
119 =head2 Exit Code
121 If the tests fail C<prove> will exit with non-zero status.
123 =head2 Arguments to Tests
125 It is possible to supply arguments to tests. To do so separate them from
126 prove's own arguments with the arisdottle, '::'. For example
128 prove -v t/mytest.t :: --url http://example.com
130 would run F<t/mytest.t> with the options '--url http://example.com'.
131 When running multiple tests they will each receive the same arguments.
133 =head2 C<--exec>
135 Normally you can just pass a list of Perl tests and the harness will know how
136 to execute them. However, if your tests are not written in Perl or if you
137 want all tests invoked exactly the same way, use the C<-e>, or C<--exec>
138 switch:
140 prove --exec '/usr/bin/ruby -w' t/
141 prove --exec '/usr/bin/perl -Tw -mstrict -Ilib' t/
142 prove --exec '/path/to/my/customer/exec'
144 =head2 C<--merge>
146 If you need to make sure your diagnostics are displayed in the correct
147 order relative to test results you can use the C<--merge> option to
148 merge the test scripts' STDERR into their STDOUT.
150 This guarantees that STDOUT (where the test results appear) and STDOUT
151 (where the diagnostics appear) will stay in sync. The harness will
152 display any diagnostics your tests emit on STDERR.
154 Caveat: this is a bit of a kludge. In particular note that if anything
155 that appears on STDERR looks like a test result the test harness will
156 get confused. Use this option only if you understand the consequences
157 and can live with the risk.
159 =head2 C<--trap>
161 The C<--trap> option will attempt to trap SIGINT (Ctrl-C) during a test
162 run and display the test summary even if the run is interrupted
164 =head2 C<--state>
166 You can ask C<prove> to remember the state of previous test runs and
167 select and/or order the tests to be run based on that saved state.
169 The C<--state> switch requires an argument which must be a comma
170 separated list of one or more of the following options.
172 =over
174 =item C<last>
176 Run the same tests as the last time the state was saved. This makes it
177 possible, for example, to recreate the ordering of a shuffled test.
179 # Run all tests in random order
180 $ prove -b --state=save --shuffle
182 # Run them again in the same order
183 $ prove -b --state=last
185 =item C<failed>
187 Run only the tests that failed on the last run.
189 # Run all tests
190 $ prove -b --state=save
192 # Run failures
193 $ prove -b --state=failed
195 If you also specify the C<save> option newly passing tests will be
196 excluded from subsequent runs.
198 # Repeat until no more failures
199 $ prove -b --state=failed,save
201 =item C<passed>
203 Run only the passed tests from last time. Useful to make sure that no
204 new problems have been introduced.
206 =item C<all>
208 Run all tests in normal order. Multple options may be specified, so to
209 run all tests with the failures from last time first:
211 $ prove -b --state=failed,all,save
213 =item C<hot>
215 Run the tests that most recently failed first. The last failure time of
216 each test is stored. The C<hot> option causes tests to be run in most-recent-
217 failure order.
219 $ prove -b --state=hot,save
221 Tests that have never failed will not be selected. To run all tests with
222 the most recently failed first use
224 $ prove -b --state=hot,all,save
226 This combination of options may also be specified thus
228 $ prove -b --state=adrian
230 =item C<todo>
232 Run any tests with todos.
234 =item C<slow>
236 Run the tests in slowest to fastest order. This is useful in conjunction
237 with the C<-j> parallel testing switch to ensure that your slowest tests
238 start running first.
240 $ prove -b --state=slow -j9
242 =item C<fast>
244 Run test tests in fastest to slowest order.
246 =item C<new>
248 Run the tests in newest to oldest order based on the modification times
249 of the test scripts.
251 =item C<old>
253 Run the tests in oldest to newest order.
255 =item C<fresh>
257 Run those test scripts that have been modified since the last test run.
259 =item C<save>
261 Save the state on exit. The state is stored in a file called F<.prove>
262 (F<_prove> on Windows and VMS) in the current directory.
264 =back
266 The C<--state> switch may be used more than once.
268 $ prove -b --state=hot --state=all,save
270 =head2 @INC
272 prove introduces a separation between "options passed to the perl which
273 runs prove" and "options passed to the perl which runs tests"; this
274 distinction is by design. Thus the perl which is running a test starts
275 with the default C<@INC>. Additional library directories can be added
276 via the C<PERL5LIB> environment variable, via -Ifoo in C<PERL5OPT> or
277 via the C<-Ilib> option to F<prove>.
279 =head2 Taint Mode
281 Normally when a Perl program is run in taint mode the contents of the
282 C<PERL5LIB> environment variable do not appear in C<@INC>.
284 Because C<PERL5LIB> is often used during testing to add build
285 directories to C<@INC> prove passes the names of any directories found
286 in C<PERL5LIB> as -I switches. The net effect of this is that
287 C<PERL5LIB> is honoured even when prove is run in taint mode.
290 =head1 FORMATTERS
292 You can load a custom L<TAP::Parser::Formatter>:
294 prove --formatter MyFormatter
296 =head1 SOURCE HANDLERS
298 You can load custom L<TAP::Parser::SourceHandler>s, to change the way the
299 parser interprets particular I<sources> of TAP.
301 prove --source MyHandler --source YetAnother t
303 If you want to provide config to the source you can use:
305 prove --source MyCustom \
306 --source Perl --perl-option 'foo=bar baz' --perl-option avg=0.278 \
307 --source File --file-option extensions=.txt --file-option extensions=.tmp t
308 --source pgTAP --pgtap-option pset=format=html --pgtap-option pset=border=2
310 Each C<--$source-option> option must specify a key/value pair separated by an
311 C<=>. If an option can take multiple values, just specify it multiple times,
312 as with the C<extensions=> examples above. If the option should be a hash
313 reference, specify the value as a second pair separated by a C<=>, as in the
314 C<pset=> examples above (escape C<=> with a backslash).
316 All C<--sources> are combined into a hash, and passed to L<TAP::Harness/new>'s
317 C<sources> parameter.
319 See L<TAP::Parser::IteratorFactory> for more details on how configuration is
320 passed to I<SourceHandlers>.
322 =head1 PLUGINS
324 Plugins can be loaded using the C<< -PI<plugin> >> syntax, eg:
326 prove -PMyPlugin
328 This will search for a module named C<App::Prove::Plugin::MyPlugin>, or failing
329 that, C<MyPlugin>. If the plugin can't be found, C<prove> will complain & exit.
331 You can pass arguments to your plugin by appending C<=arg1,arg2,etc> to the
332 plugin name:
334 prove -PMyPlugin=fou,du,fafa
336 Please check individual plugin documentation for more details.
