NOTES
.proverc
If ~/.proverc or ./.proverc exist they will be read and any
options they contain processed before the command line
options. Options in .proverc are specified in the same way
as command line options:
# .proverc
--state=hot,fast,save
-j9 --fork
Additional option files may be specified with the "--rc"
option. Default option file processing is disabled by the
"--norc" option.
Under Windows and VMS the option file is named _proverc
rather than .proverc and is sought only in the current
directory.
Reading from "STDIN"
If you have a list of tests (or URLs, or anything else you
want to test) in a file, you can add them to your tests by
using a '-':
prove - < my_list_of_things_to_test.txt
See the "README" in the "examples" directory of this
distribution.

Default Test Directory
If no files or directories are supplied, "prove" looks for
all files matching the pattern "t/*.t".
Colored Test Output
Colored test output is the default, but if output is not to
a terminal, color is disabled. You can override this by
adding the "--color" switch.
Color support requires Term::ANSIColor on Unix-like
platforms and Win32::Console windows. If the necessary
module is not installed colored output will not be
available.
Exit Code
If the tests fail "prove" will exit with non-zero status.
Arguments to Tests
It is possible to supply arguments to tests. To do so
separate them from prove's own arguments with the
arisdottle, '::'. For example
prove -v t/mytest.t :: --url http://example.com
would run t/mytest.t with the options '--url
http://example.com'. When running multiple tests they will
each receive the same arguments.
"--exec"
Normally you can just pass a list of Perl tests and the
harness will know how to execute them. However, if your
tests are not written in Perl or if you want all tests
invoked exactly the same way, use the "-e", or "--exec"
switch:
prove --exec '/usr/bin/ruby -w' t/
prove --exec '/usr/bin/perl -Tw -mstrict -Ilib' t/
prove --exec '/path/to/my/customer/exec'
"--merge"
If you need to make sure your diagnostics are displayed in
the correct order relative to test results you can use the
"--merge" option to merge the test scripts' STDERR into
their STDOUT.
This guarantees that STDOUT (where the test results appear)
and STDOUT (where the diagnostics appear) will stay in sync.
The harness will display any diagnostics your tests emit on
STDERR.
Caveat: this is a bit of a kludge. In particular note that
if anything that appears on STDERR looks like a test result

the test harness will get confused. Use this option only if
you understand the consequences and can live with the risk.
"--state"
You can ask "prove" to remember the state of previous test
runs and select and/or order the tests to be run based on
that saved state.
The "--state" switch requires an argument which must be a
comma separated list of one or more of the following
options.
"last"
Run the same tests as the last time the state was saved.
This makes it possible, for example, to recreate the
ordering of a shuffled test.
# Run all tests in random order
$ prove -b --state=save --shuffle
# Run them again in the same order
$ prove -b --state=last
"failed"
Run only the tests that failed on the last run.
# Run all tests
$ prove -b --state=save
# Run failures
$ prove -b --state=failed
If you also specify the "save" option newly passing
tests will be excluded from subsequent runs.
# Repeat until no more failures
$ prove -b --state=failed,save
"passed"
Run only the passed tests from last time. Useful to make
sure that no new problems have been introduced.
"all"
Run all tests in normal order. Multple options may be
specified, so to run all tests with the failures from
last time first:
$ prove -b --state=failed,all,save
"hot"
Run the tests that most recently failed first. The last
failure time of each test is stored. The "hot" option
perl v5.12.5 Last change: 2014-06-17 4
Perl Programmers Reference Guide PROVE(1)
causes tests to be run in most-recent- failure order.
$ prove -b --state=hot,save
Tests that have never failed will not be selected. To
run all tests with the most recently failed first use
$ prove -b --state=hot,all,save
This combination of options may also be specified thus
$ prove -b --state=adrian
"todo"
Run any tests with todos.
"slow"
Run the tests in slowest to fastest order. This is
useful in conjunction with the "-j" parallel testing
switch to ensure that your slowest tests start running
first.
$ prove -b --state=slow -j9
"fast"
Run test tests in fastest to slowest order.
"new"
Run the tests in newest to oldest order based on the
modification times of the test scripts.
"old"
Run the tests in oldest to newest order.
"fresh"
Run those test scripts that have been modified since the
last test run.
"save"
Save the state on exit. The state is stored in a file
called .prove (_prove on Windows and VMS) in the current
directory.
The "--state" switch may be used more than once.
$ prove -b --state=hot --state=all,save
@INC
prove introduces a separation between "options passed to the
perl which runs prove" and "options passed to the perl which
runs tests"; this distinction is by design. Thus the perl
which is running a test starts with the default @INC.

Perl Programmers Reference Guide PROVE(1)
Additional library directories can be added via the
"PERL5LIB" environment variable, via -Ifoo in "PERL5OPT" or
via the "-Ilib" option to prove.
Taint Mode
Normally when a Perl program is run in taint mode the
contents of the "PERL5LIB" environment variable do not
appear in @INC.
Because "PERL5LIB" is often used during testing to add build
directories to @INC prove (actually
TAP::Parser::Source::Perl) passes the names of any
directories found in "PERL5LIB" as -I switches. The net
effect of this is that "PERL5LIB" is honoured even when
prove is run in taint mode.
PLUGINS
Plugins can be loaded using the "-Pplugin" syntax, eg:
prove -PMyPlugin
This will search for a module named
"App::Prove::Plugin::MyPlugin", or failing that, "MyPlugin".
If the plugin can't be found, "prove" will complain & exit.
You can pass arguments to your plugin by appending
"=arg1,arg2,etc" to the plugin name:
prove -PMyPlugin=fou,du,fafa
Please check individual plugin documentation for more
details.
