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
- --reload
- -r
- --no-reload
-
Attempt to reload modified modules in-place, restarting entire stages only when necessary.
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
- --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 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
- --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
- --resource Port
- --resource +Test2::Harness::Runner::Resource::Port

- --no-resource
-
Use a resource module to assign resource assignments to individual 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
