App::Yath::Finder(3)

NAME
App::Yath::Finder - Library that searches for test files

DESCRIPTION
The finder is responsible for locating test files that should be run. You can subclass the finder and instruct yath to use your subclass.

SYNOPSIS

  USING A CUSTOM FINDER
To use App::Yath::Finder::MyFinder:

    $ yath test --finder MyFinder

To use Another::Finder

    $ yath test --finder +Another::Finder

By default "App::Yath::Finder::" is prefixed onto your custom finder, use '+' before the class name or prevent this.

  SUBCLASSING
    use parent 'App::Yath::Finder';
    use Test2::Harness::TestFile;

    # Custom finders may provide their own options if desired.
    # This is optional.
    use Getopt::Yath;
    option foo => (
        ...
    );

    # This is the main method to override.
    sub find_project_files {
        my $self = shift;
        my ($plugins, $search) = @_;

        return [
            Test2::Harness::TestFile->new(...),
            Test2::Harness::TestFile->new(...),
            ...,
        ];
    }

METHODS
These are important state methods, as well as utility methods for use in your subclasses.

$arrayref = $finder->find_files($plugins)
    This is the main method. This method returns an arrayref of Test2::Harness::TestFile instances, each one representing a single test to run.

    $plugins is a list of plugins, some may be class names, others may be instances.

    Note: In many cases it is better to override find_project_files() in your subclasses.

$durations = $finder->duration_data
    This will fetch the durations data if any was provided. This is a hashref of relative test paths as keys where the value is the duration of the file (SHORT, MEDIUM or LONG).

    Note: The result is cached, see pull_durations() to refresh the data.

@reasons = $finder->exclude_file($test)
    The input argument should be an Test2::Harness::Test instance. This will return a list of human readible reasons a test file should be excluded. If the file should not be excluded the list will be empty.

    This is a utility method that verifies the file is not in an exclude list/pattern. The reasons are provided back in case you need to inform the user.

$bool = $finder->include_file($test)
    The input argument should be an Test2::Harness::Test instance. This is a convenience method around exclude_file(), it will return true when exclude_file() returns an empty list.

$arrayref = $finder->find_project_files($plugins, $search)
    These do the heavy lifting for "find_files"

    The default find_files() implementation is this:

        sub find_files {
            my $self = shift;
            my ($plugins) = @_;

            return $self->find_project_files($plugins, $self->search);
        }

    Each one returns an arrayref of Test2::Harness::TestFile instances.

    $plugins is a list of plugins, some may be class names, others may be instances.

    $search is an arrayref of search paths.

$finder->pull_durations
    This will fetch the durations data if ant was provided. This is a hashref of relative test paths as keys where the value is the duration of the file (SHORT, MEDIUM or LONG).

    duration_data() is a cached version of this. This method will refresh the cache for the other.
