App::Yath::Command::speedtag - Tag tests with duration (short medium long) using a source log


This command will read the test durations from a log and tag/retag all tests from the log based on the max durations for each type.


    $ yath [YATH OPTIONS] speedtag [COMMAND OPTIONS]




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


--persist-dir ARG

Where to find persistence files.

--persist-file ARG
--pfile ARG

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-name ARG

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.

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.
