Plugin to collect and report basic coverage data

## NAME

App::Yath::Plugin::Cover - Plugin to collect and report basic coverage data

## DESCRIPTION

Simple coverage data, file and sub coverage only. Use Devel::Cover if you want deep coverage stats.

## PROVIDED OPTIONS

### COMMAND OPTIONS

*Cover Options*

- \--cover-aggregator ByTest

  - \--cover-aggregator ByRun

  - \--cover-aggregator +Custom::Aggregator

  - \--cover-agg ByTest

  - \--cover-agg ByRun

  - \--cover-agg +Custom::Aggregator

  - \--no-cover-aggregator

  Choose a custom aggregator subclass

- \--cover-class ARG

  - \--cover-class=ARG

  - \--no-cover-class

  Choose a Test2::Plugin::Cover subclass

- \--cover-dirs ARG

  - \--cover-dirs=ARG

  - \--cover-dir ARG

  - \--cover-dir=ARG

  - \--no-cover-dirs

  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).
