.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"
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.
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.
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'
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.
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
# Run all tests in random order
$ prove -b --state=save --shuffle
# Run them again in the same order
$ prove -b --state=last
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
Run only the passed tests from last time. Useful to make sure that
no new problems have been introduced.
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
Run the tests that most recently failed first. The last failure
time of each test is stored. The "hot" option 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
Run any tests with todos.
Run the tests in newest to oldest order based on the modification
times of the test scripts.
Run the tests in oldest to newest order.
Run those test scripts that have been modified since the last test
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
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. Additional library directories can be added via
the "PERL5LIB" environment variable, via -Ifoo in "PERL5OPT" or via the
"-Ilib" option to prove.
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 can be loaded using the "-Pplugin" syntax, eg:
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:
