NAME

App::Yath::Command::start - Start the persistent test runner

DESCRIPTION

This command is used to start a persistant instance of yath. A persistant instance is useful because it allows you to preload modules in advance, reducing start time for any tests you decide to run as you work.

A running instance will watch for changes to any preloaded files, and restart itself if anything changes. Changed files are blacklisted for subsequent reloads so that reloading is not a frequent occurence when editing the same file over and over again.

USAGE

$ yath [YATH OPTIONS] start [COMMAND OPTIONS]

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.

Help and Debugging

--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 it 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.

Can be specified multiple times

COMMAND OPTIONS

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

--dummy
-d
--no-dummy

Dummy run, do not actually execute anything

Can also be set with the following environment variables: T2_HARNESS_DUMMY

--help
-h
--no-help

exit after showing help information

--keep-dirs
--keep_dir
-k
--no-keep-dirs

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

Persistent Runner Options

--quiet
-q
--no-quiet

Be very quiet.

Can be specified multiple times

Runner Options

--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

--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)

--daemon
--no-daemon

Start the runner as a daemon (Default: True)

--dbi-profiling
--no-dbi-profiling

Use Test2::Plugin::DBIProfile to collect database profiling data

--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 ARG
--job-count=ARG
--jobs ARG
--jobs=ARG
-j ARG
-j=ARG
--no-job-count

Set the number of concurrent jobs to run (Default: 1)

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

--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

--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

--use-timeout
--timeout
--no-use-timeout

(default: on) Enable/disable timeouts

Workspace Options

--clear
-C
--no-clear

Clear the work directory if it is not already empty

--tmp-dir ARG
--tmp-dir=ARG
--tmpdir ARG
--tmpdir=ARG
-t ARG
-t=ARG
--no-tmp-dir

Use a specific temp directory (Default: use system temp dir)

Can also be set with the following environment variables: T2_HARNESS_TEMP_DIR, YATH_TEMP_DIR, TMPDIR, TEMPDIR, TMP_DIR, TEMP_DIR

--workdir ARG
--workdir=ARG
-w ARG
-w=ARG
--no-workdir

Set the work directory (Default: new temp directory)

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

YathUI Options

--yathui-api-key ARG
--yathui-api-key=ARG
--no-yathui-api-key

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

--yathui-grace
--no-yathui-grace

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

--yathui-long-duration 10
--no-yathui-long-duration

Minimum duration length (seconds) before a test goes from MEDIUM to LONG

--yathui-medium-duration 5
--no-yathui-medium-duration

Minimum duration length (seconds) before a test goes from SHORT to MEDIUM

--yathui-mode summary
--yathui-mode qvf
--yathui-mode qvfd
--yathui-mode complete
--no-yathui-mode

Set the upload mode (default 'qvfd')

--yathui-project ARG
--yathui-project=ARG
--no-yathui-project

The Yath-UI project for your test results

--yathui-retry
--no-yathui-retry

How many times to try an operation before giving up

Can be specified multiple times
