NAME

DESCRIPTION

startup - Time from launch to first test event.

events - Time spent generating test events.

cleanup - Time from last test event to test exit.

total - Total time.

SYNOPSIS

    use Test2::Harness::Auditor::TimeTracker;

    my $tracker = Test2::Harness::Auditor::TimeTracker->new();

    my $assert_count = 0;
    for my $event (@events) {
        my $facet_data = $events->facet_data;
        $assert_count++ if $facet_data->{assert};
        $tracker->process($event, $facet_data, $assert_count);
    }

    print $tracker->summary;
    # Startup: 0.00708s | Events: 0.00000s | Cleanup: 0.10390s | Total: 0.11098s

METHODS

$tracker->process($event, $facet_data, $assert_count)

$tracker->process($event, undef, $assert_count)

TimeTracker builds its state from multiple events, each event should be processed by this method.

The second argument is optional, if no facet_data is provided it will pull the facet_data from the event itself. This is mainly a micro-optimization to avoid calling the "facet_data()" method on the event multiple times if you have already called it.

$bool = $tracker->useful()

Returns true if there is any useful data to display.

$totals = $tracker->totals()

Returns the totals like this:

    {
        # Raw numbers
        startup => ...,
        events  => ...,
        cleanup => ...,
        total   => ...,

        # Human friendly versions
        h_startup => ...,
        h_events  => ...,
        h_cleanup => ...,
        h_total   => ...,
    }
    

$source = $tracker->source()

This method returns the data from which the totals are derived.

    {
        start => ...,    # timestamp of the job starting
        stop  => ...,    # timestamp of the job ending
        first => ...,    # timestamp of the first non-harness event
        last  => ...,    # timestamp of the last non-harness event

        # These are event_id's of the events that provided the above stamps.
        start_id    => ...,
        stop_id     => ...,
        first_id    => ...,
        last_id     => ...,
        complete_id => ...,
    }
    

$data = $tracker->data_dump

This dumps the totals and source data:

    {
        totals => $tracker->totals,
        source => $tracker->source,
    }
    

$string = $tracker->summary

This produces a summary string of the totals data:

    Startup: 0.00708s | Events: 0.00000s | Cleanup: 0.10390s | Total: 0.11098s
    

Fields that have no data will be ommited from the string.

$table = $tracker->table

Returns this structure that is good for use in Term::Table.

    {
        header => ["Phase", "Time", "Raw", "Explanation"],
        rows   => [
            ['startup', $human_readible, $raw, "Time from launch to first test event."],
            ['events',  $human_radible,  $raw, 'Time spent generating test events.'],
            ['cleanup', $human_radible,  $raw, 'Time from last test event to test exit.'],
            ['total',   $human_radible,  $raw, 'Total time.'],
        ],
    }
    

@items = $tracker->job_fields()

This is used to obtain extra data to attach to the job completion event.
