YATH OPTIONS¶

Developer

--dev-lib

--dev-lib=lib

-D

-D=lib

-Dlib

--no-dev-lib

Add paths to @INC before loading ANYTHING. 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.

Can be specified multiple times

Environment

--persist-dir ARG

--persist-dir=ARG

--no-persist-dir

Where to find persistence files.

--persist-file ARG

--persist-file=ARG

--pfile ARG

--pfile=ARG

--no-persist-file

Where to find the persistence file. The default is /{system-tempdir}/project-yath-persist.json. If no project is specified then it will fall back to the current directory. If the current directory is not writable it will default to /tmp/yath-persist.json which limits you to one persistent runner on your system.

--project ARG

--project=ARG

--project-name ARG

--project-name=ARG

--no-project

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

--show-opts

--no-show-opts

Exit after showing what yath thinks your options mean

--version

-V

--no-version

Exit after showing a helpful usage message

Plugins

--no-scan-plugins

--no-no-scan-plugins

Normally yath scans for and loads all App::Yath::Plugin::* modules in order to bring in command-line options they may provide. This flag will disable that. This is useful if you have a naughty plugin that is loading other modules when it should not.

--plugins PLUGIN

--plugins +App::Yath::Plugin::PLUGIN

--plugins PLUGIN=arg1,arg2,...

--plugin PLUGIN

--plugin +App::Yath::Plugin::PLUGIN

--plugin PLUGIN=arg1,arg2,...

-pPLUGIN

--no-plugins

Load a yath plugin.

--max-poll-events 1000

--no-max-poll-events

Maximum number of events to poll from a job before jumping to the next job. (Default: 1000)

NO DESCRIPTION - FIX ME

Can be specified multiple times

--cover-exclude-private

--no-cover-exclude-private

--cover-files

--no-cover-files

Use Test2::Plugin::Cover to collect coverage data for what files are touched by what tests. Unlike Devel::Cover this has very little performance impact (About 4% difference)

--cover-from path/to/log.jsonl

--cover-from http://example.com/coverage

--cover-from path/to/coverage.jsonl

--no-cover-from

This can be a test log, a coverage dump (old style json or new jsonl format), or a url to any of the previous. Tests will not be run if the file/url is invalid.

--cover-from-type json

--cover-from-type jsonl

--cover-from-type log

--no-cover-from-type

File type for coverage source. Usually it can be detected, but when it cannot be you should specify. "json" is old style single-blob coverage data, "jsonl" is the new by-test style, "log" is a logfile from a previous run.

--cover-manager My::Coverage::Manager

--no-cover-manager

Coverage 'from' manager to use when coverage data does not provide one

--cover-maybe-from path/to/log.jsonl

--cover-maybe-from http://example.com/coverage

--cover-maybe-from path/to/coverage.jsonl

--no-cover-maybe-from

This can be a test log, a coverage dump (old style json or new jsonl format), or a url to any of the previous. Tests will coninue if even if the coverage file/url is invalid.

--cover-maybe-from-type json

--cover-maybe-from-type jsonl

--cover-maybe-from-type log

--no-cover-maybe-from-type

Same as "from_type" but for "maybe_from". Defaults to "from_type" if that is specified, otherwise auto-detect

--cover-metrics

--no-cover-metrics

--cover-types ARG

--cover-types=ARG

--cover-type ARG

--cover-type=ARG

--no-cover-types

NO DESCRIPTION - FIX ME

Can be specified multiple times

--cover-write

--no-cover-write

Create a json or jsonl file of all coverage data seen during the run (This implies --cover-files).

Git Options

--git-change-base master

--git-change-base HEAD^

--git-change-base df22abe4

--no-git-change-base

Find files changed by all commits in the current branch from most recent stopping when a commit is found that is also present in the history of the branch/commit specified as the change base.

Help and Debugging

Persistent Runner Options

--quiet

-q

-r

--no-reload

Attempt to reload modified modules in-place, restarting entire stages only when necessary.

Can be specified multiple times

Runner Options

--abort-on-bail

--no-abort-on-bail

Abort all testing if a bail-out is encountered (default: on)

--blib

-b

--no-blib

(Default: include if it exists) Include 'blib/lib' and 'blib/arch' in your module path

--cover

--cover=-silent,1,+ignore,^t/,+ignore,^t2/,+ignore,^xt,+ignore,^test.pl

--no-cover

Use Devel::Cover to calculate test coverage. This disables forking. If no args are specified the following are used: -silent,1,+ignore,^t/,+ignore,^t2/,+ignore,^xt,+ignore,^test.pl

--daemon

--no-daemon

Start the runner as a daemon (Default: True)

--dump-depmap

--no-dump-depmap

When using staged preload, dump the depmap for each stage as json files

--event-timeout SECONDS

--et 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.

--include ARG

--include=ARG

-I ARG

-I=ARG

--no-include

Add a directory to your include paths

Can be specified multiple times

--job-count 4

--job-count 8:2

--jobs 4

--jobs 8:2

-j4

-j8:2

--no-job-count

Set the number of concurrent jobs to run. Add a :# if you also wish to designate multiple slots per test. 8:2 means 8 slots, but each test gets 2 slots, so 4 tests run concurrently. Tests can find their concurrency assignemnt in the "T2_HARNESS_MY_JOB_CONCURRENCY" environment variable.

Can also be set with the following environment variables: "YATH_JOB_COUNT", "T2_HARNESS_JOB_COUNT", "HARNESS_JOB_COUNT"

--lib

-l

--no-lib

(Default: include if it exists) Include 'lib' in your module path

--nytprof

--no-nytprof

Use Devel::NYTProf on tests. This will set addpid=1 for you. This works with or without fork.

--post-exit-timeout SECONDS

--pet 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.

--preload-threshold ARG

--preload-threshold=ARG

--Pt ARG

--Pt=ARG

-W ARG

-W=ARG

--no-preload-threshold

Only do preload if at least N tests are going to be run. In some cases a full preload takes longer than simply running the tests, this lets you specify a minimum number of test jobs that will be run for preload to happen. This has no effect for a persistent runner. The default is 0, and it means always preload.

--preloads ARG

--preloads=ARG

--preload ARG

--preload=ARG

-P ARG

-P=ARG

--no-preloads

Preload a module before running tests

Can be specified multiple times

--shared-jobs-config /absolute/path/.sharedjobslots.yml

--no-shared-jobs-config

--slots-per-job 2

-x2

--no-slots-per-job

This sets the number of slots each job will use (default 1). This is normally set by the ':#' in '-j#:#'.

Can also be set with the following environment variables: "T2_HARNESS_JOB_CONCURRENCY"

--switch ARG

--switch=ARG

-S ARG

-S=ARG

--no-switch

Pass the specified switch to perl for each test. This is not compatible with preload.

Can be specified multiple times

--tlib

--no-tlib

(Default: off) Include 't/lib' in your module path

--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"

--use-fork

--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"
