prove - Run tests through a TAP harness.
prove [options] [files or directories]
-v, --verbose Print all test lines. -l, --lib Add 'lib' to the path for your tests (-Ilib). -b, --blib Add 'blib/lib' to the path for your tests (-Iblib/lib). -s, --shuffle Run the tests in random order. -c, --color Colored test output (default). See TAP::Harness::Color. --nocolor Do not color test output. -f, --failures Only show failed tests. -m, --merge Merge test scripts' STDERR with their STDOUT. -r, --recurse Recursively descend into directories. --reverse Run the tests in reverse order. -q, --quiet Suppress some test output while running tests. -Q, --QUIET Only print summary results. -p, --parse Show full list of TAP parse errors, if any. --directives Only show results with TODO or SKIP directives. -T Enable tainting checks. -t Enable tainting warnings. -W Enable fatal warnings. -w Enable warnings. -h, --help Display this help -?, Display this help -H, --man Longer manpage for prove
Options which take arguments
-I Library paths to include. -e, --exec Interpreter to run the tests ('' for compiled tests.) --harness Define test harness to use. See TAP::Harness. --formatter Result formatter to use. See TAP::Harness. -a, --archive Store the resulting TAP into the specified archive file.
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
README in the
examples directory of this distribution.
If no files or directories are supplied,
prove looks for all files matching the pattern
-c switch is the same as:
prove --harness TAP::Harness::Color
Colored test output is the default, but if output is not to a terminal, color is disabled. You can override this by adding the
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
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.
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.
Because of its design,
TAP::Parser collects more information than
Test::Harness. However, the trade-off is sometimes slightly slower performance than when using the
prove utility which is bundled with Test::Harness. For small tests suites, this is usually not a problem. However, enabling the
--QUIET options can sometimes speed up the test suite, sometimes running faster than
prove, which comes with Test::Harness and whose code I've nicked in a few places (thanks Andy!).
This is alpha code. You've been warned.
