Test2::EventFacet::Info - Facet for information a developer might care about.


This facet represents messages intended for humans that will help them either understand a result, or diagnose a failure.


This facet appears in a list instead of being a single item.


$string_or_structure = $info->{details}
$string_or_structure = $info->details()

Human readable string or data structure, this is the information to display. Formatters are free to render the structures however they please. This may contain a blessed object.

If the table attribute (see below) is set then a renderer may choose to display the table instead of the details.

$structure = $info->{table}
$structure = $info->table()

If the data the info facet needs to convey can be represented as a table then the data may be placed in this attribute in a more raw form for better display. The data must also be represented in the details attribute for renderers which do not support rendering tables directly.

The table structure:

my %table = {
    header => [ 'column 1 header', 'column 2 header', ... ], # Optional

    rows => [
        ['row 1 column 1', 'row 1, column 2', ... ],
        ['row 2 column 1', 'row 2, column 2', ... ],

    # Allow the renderer to hide empty columns when true, Optional
    collapse => $BOOL,

    # List by name or number columns that should never be collapsed
    no_collapse => \@LIST,
$short_string = $info->{tag}
$short_string = $info->tag()

Short tag to categorize the info. This is usually 10 characters or less, formatters may truncate longer tags.

$bool = $info->{debug}
$bool = $info->debug()

Set this to true if the message is critical, or explains a failure. This is info that should be displayed by formatters even in less-verbose modes.

When false the information is not considered critical and may not be rendered in less-verbose modes.

$bool = $info->{important}
$bool = $info->important

This should be set for non debug messages that are still important enough to show when a formatter is in quiet mode. A formatter should send these to STDOUT not STDERR, but should show them even in non-verbose mode.
