=head1 NAME

App::Yath::Options::Run - Run options for Yath.

=head1 DESCRIPTION

This is where command lines options for a single test run are defined.

=head1 PROVIDED OPTIONS

=head2 COMMAND OPTIONS

=head3 Run Options

=over 4

=item --author-testing

=item -A

=item --no-author-testing

This will set the AUTHOR_TESTING environment to true


=item --dbi-profiling

=item --no-dbi-profiling

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


=item --env-var VAR=VAL

=item -EVAR=VAL

=item -E VAR=VAL

=item --no-env-var

Set environment variables to set when each test is run.

Can be specified multiple times


=item --event-uuids

=item --uuids

=item --no-event-uuids

Use Test2::Plugin::UUID inside tests (default: on)


=item --fields name:details

=item --fields JSON_STRING

=item -f name:details

=item -f JSON_STRING

=item --no-fields

Add custom data to the harness run

Can be specified multiple times


=item --input ARG

=item --input=ARG

=item --no-input

Input string to be used as standard input for ALL tests. See also: --input-file


=item --input-file ARG

=item --input-file=ARG

=item --no-input-file

Use the specified file as standard input to ALL tests


=item --io-events

=item --no-io-events

Use Test2::Plugin::IOEvents inside tests to turn all prints into test2 events (default: off)


=item --link 'https://travis.work/builds/42'

=item --link 'https://jenkins.work/job/42'

=item --link 'https://buildbot.work/builders/foo/builds/42'

=item --no-link

Provide one or more links people can follow to see more about this run.

Can be specified multiple times


=item --load ARG

=item --load=ARG

=item --load-module ARG

=item --load-module=ARG

=item -m ARG

=item -m=ARG

=item --no-load

Load a module in each test (after fork). The "import" method is not called.

Can be specified multiple times


=item --load-import Module

=item --load-import Module=import_arg1,arg2,...

=item --loadim Module

=item --loadim Module=import_arg1,arg2,...

=item -M Module

=item -M Module=import_arg1,arg2,...

=item --no-load-import

Load a module in each test (after fork). Import is called.

Can be specified multiple times. If the same key is listed multiple times the value lists will be appended together.


=item --mem-usage

=item --no-mem-usage

Use Test2::Plugin::MemUsage inside tests (default: on)


=item --retry ARG

=item --retry=ARG

=item -r ARG

=item -r=ARG

=item --no-retry

Run any jobs that failed a second time. NOTE: --retry=1 means failing tests will be attempted twice!


=item --retry-isolated

=item --retry-iso

=item --no-retry-isolated

If true then any job retries will be done in isolation (as though -j1 was set)


=item --run-id

=item --id

=item --no-run-id

Set a specific run-id. (Default: a UUID)


=item --test-args ARG

=item --test-args=ARG

=item --no-test-args

Arguments to pass in as @ARGV for all tests that are run. These can be provided easier using the '::' argument separator.

Can be specified multiple times


=item --stream

=item --no-stream

Use the stream formatter (default is on)


=item --tap

=item --TAP

=item ----no-stream

=item --no-tap

The TAP format is lossy and clunky. Test2::Harness normally uses a newer streaming format to receive test results. There are old/legacy tests where this causes problems, in which case setting --TAP or --no-stream can help.
