--et SECONDS

--event-timeout SECONDS

--no-event-timeout

Kill test if no output is received within timeout period. (Default: 60 seconds). Add the "# HARNESS-NO-TIMEOUT" comment to the top of a test file to disable timeouts on a per-test basis. This prevents a hung test from running forever.

--no-event-uuids

Use Test2::Plugin::UUID inside tests (default: on)

-I ARG

-I=ARG

-I '*.*'

-I='*.*'

--input-file=ARG

--no-input-file

Use the specified file as standard input to ALL tests

Load a module in each test (after fork). The "import" method is not called.

Note: Can be specified multiple times

-M Module

-M Module=import_arg1,arg2,...

-M '{"Data::Dumper":["Dumper"]}'

--loadim Module

--load-import Module

--loadim Module=import_arg1,arg2,...

--loadim '{"Data::Dumper":["Dumper"]}'

Note: Can be specified multiple times

--mem-usage

--no-mem-usage

Use Test2::Plugin::MemUsage inside tests (default: on)

--pet SECONDS

--post-exit-timeout SECONDS

--no-post-exit-timeout

Stop waiting post-exit after the timeout period. (Default: 15 seconds) Some tests fork and allow the parent to exit before writing all their output. If Test2::Harness detects an incomplete plan after the test exits it will monitor for more events until the timeout period. Add the "# HARNESS-NO-TIMEOUT" comment to the top of a test file to disable timeouts on a per-test basis.

-rARG

-r ARG

-r=ARG

--retry ARG

--retry=ARG

--no-retry

Run any jobs that failed a second time. NOTE: --retry=1 means failing tests will be attempted twice!

--retry-iso

--retry-isolated

--no-retry-isolated

If true then any job retries will be done in isolation (as though -j1 was set)

--stream

--use-stream

--no-stream

--TAP

The TAP format is lossy and clunky. Test2::Harness normally uses a newer streaming format to receive test results. There are old/legacy tests where this causes problems, in which case setting --TAP or --no-stream can help.

-S=ARG

-S '["json","list"]'

-S='["json","list"]'

-S :{ ARG1 ARG2 ... }:

-S=:{ ARG1 ARG2 ... }:

--test-arg=:{ ARG1 ARG2 ... }:

--test-args :{ ARG1 ARG2 ... }:

--test-args=:{ ARG1 ARG2 ... }:

--no-test-args

Arguments to pass in as @ARGV for all tests that are run. These can be provided easier using the '::' argument separator.

Note: Can be specified multiple times

--tlib

--no-tlib

(Default: off) Include 't/lib' in your module path (These will come after paths you specify with -D or -I)

--unsafe-inc

--no-unsafe-inc

perl is removing '.' from @INC as a security concern. This option keeps things from breaking for now.

Can also be set with the following environment variables: PERL_USE_UNSAFE_INC

The following environment variables will be set after arguments are processed: PERL_USE_UNSAFE_INC

--fork

--use-fork

--no-use-fork

(default: on, except on windows) Normally tests are run by forking, which allows for features like preloading. This will turn off the behavior globally (which is not compatible with preloading). This is slower, it is better to tag misbehaving tests with the '# HARNESS-NO-PRELOAD' comment in their header to disable forking only for those tests.

Can also be set with the following environment variables: !T2_NO_FORK, T2_HARNESS_FORK, !T2_HARNESS_NO_FORK, YATH_FORK, !YATH_NO_FORK

--timeout

--use-timeout

--no-use-timeout

(default: on) Enable/disable timeouts

Web Client Options

Yath server API key. This is not necessary if your Yath server instance is set to single-user

Can also be set with the following environment variables: YATH_API_KEY

--grace

--no-grace

If yath cannot connect to a server it normally throws an error, use this to make it fail gracefully. You get a warning, but things keep going.

--request-retry

--request-retry=COUNT

--no-request-retry

How many times to try an operation before giving up

Note: Can be specified multiple times, counter bumps each time it is used.

--url http://my-yath-server.com/...

--uri http://my-yath-server.com/...

--no-url

Yath server url

Can also be set with the following environment variables: YATH_URL

Workspace Options

-C

--clear

--no-clear

Clear the work directory if it is not already empty

-k

--keep-dir

--keep-dirs

--no-keep-dirs

Do not delete directories when done. This is useful if you want to inspect the directories used for various commands.

--tmpdir ARG

--tmpdir=ARG

--tmp-dir ARG

--tmp-dir=ARG

--no-tmpdir

Use a specific temp directory (Default: create a temp dir under the system one)

Can also be set with the following environment variables: T2_HARNESS_TEMP_DIR, YATH_TEMP_DIR

The following environment variables will be cleared after arguments are processed: T2_HARNESS_TEMP_DIR, YATH_TEMP_DIR

The following environment variables will be set after arguments are processed: TMPDIR, TEMPDIR, TMP_DIR, TEMP_DIR

--workdir ARG

--workdir=ARG

--no-workdir

Set the work directory (Default: new temp directory)

Can also be set with the following environment variables: T2_WORKDIR, YATH_WORKDIR

The following environment variables will be cleared after arguments are processed: T2_WORKDIR, YATH_WORKDIR

Yath Options

--base-dir ARG

--base-dir=ARG

--no-base-dir

Root directory for the project being tested (usually where .yath.rc lives)

-D

-Dlib

-Dlib

-D=lib

-D"lib/*"

--dev-lib

--dev-lib=lib

--dev-lib="lib/*"

--no-dev-lib

This is what you use if you are developing yath or yath plugins to make sure the yath script finds the local code instead of the installed versions of the same code. You can provide an argument (-Dfoo) to provide a custom path, or you can just use -D without and arg to add lib, blib/lib and blib/arch.

Note: This option can cause yath to use exec() to reload itself with the correct libraries in place. Each occurence of this argument can cause an additional exec() call. Use --dev-libs-verbose BEFORE any -D calls to see the exec() calls.

Note: Can be specified multiple times

--dev-libs-verbose

--no-dev-libs-verbose

Be verbose and announce that yath will re-exec in order to have the correct includes (normally yath will just call exec() quietly)

-h=Group

--help

--help=Group

--no-help

exit after showing help information

Note: Can be specified multiple times

--project ARG

--project=ARG

This lets you provide a label for your current project/codebase. This is best used in a .yath.rc file.

--scan-options key=val

--scan-options=key=val

--scan-options '{"json":"hash"}'

--scan-options='{"json":"hash"}'

--scan-options(?^:^--(no-)?(?^:scan-(.+))$)

--scan-options :{ KEY1 VAL KEY2 :{ VAL1 VAL2 ... }: ... }:

--scan-options=:{ KEY1 VAL KEY2 :{ VAL1 VAL2 ... }: ... }:

--no-scan-options

/^--(no-)?scan-(.+)$/

Yath will normally scan plugins for options. Some commands scan other libraries (finders, resources, renderers, etc) for options. You can use this to disable all scanning, or selectively disable/enable some scanning.

Note: This is parsed early in the argument processing sequence, before options that may be earlier in your argument list.

Note: Can be specified multiple times

--show-opts

--show-opts=group

--no-show-opts

Exit after showing what yath thinks your options mean
