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 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 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
--cover-write=coverage.jsonl
--cover-write=coverage.json
--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

directories used for various commands.
--procname-prefix ARG
--procname-prefix=ARG
--no-procname-prefix
Add a prefix to all proc names (as seen by ps).
Persistent Runner Options
--quiet

Can be specified multiple times
--reload
-r
--no-reload
Attempt to reload modified modules in-place, restarting entire stages only when
necessary.
--restrict-reload
--restrict-reload=path
--no-restrict-reload
Only reload modules under the specified path, if no path is specified look at anything
under the .yath.rc path, or the current working directory.
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 .sharedjobslots.yml
--shared-jobs-config relative/path/.sharedjobslots.yml
--shared-jobs-config /absolute/path/.sharedjobslots.yml
--no-shared-jobs-config
Where to look for a shared slot config file. If a filename with no path is provided
yath will search the current and all parent directories for the name.
--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"
