#NAME

Dancer2::Logger::Capture - Capture dancer logs

#VERSION

version 1.1.2

#SYNOPSIS

The basics:

set logger => "capture";

my $trap = dancer_app->logger_engine->trapper;
my $logs = $trap->read;

A worked-out real-world example:

use Test::More tests => 2;
use Dancer2;

set logger => 'capture';

warning "Danger!  Warning!";
debug   "I like pie.";

my $trap = dancer_app->logger_engine->trapper;

is_deeply $trap->read, [
    { level => "warning", message => "Danger!  Warning!" },
    { level => "debug",   message => "I like pie.", }
];

# each call to read cleans the trap
is_deeply $trap->read, [];

#DESCRIPTION

This is a logger class for Dancer2 which captures all logs to an object.

Its primary purpose is for testing. Here is an example of a test:

use strict;
use warnings;
use Test::More;
use Plack::Test;
use HTTP::Request::Common;
use Ref::Util qw<is_coderef>;

{
    package App;
    use Dancer2;

    set log       => 'debug';
    set logger    => 'capture';

    get '/' => sub {
        log(debug => 'this is my debug message');
        log(core  => 'this should not be logged');
        log(info  => 'this is my info message');
    };
}

my $app = Dancer2->psgi_app;
ok( is_coderef($app), 'Got app' );

test_psgi $app, sub {
    my $cb = shift;

    my $res = $cb->( GET '/' );

    my $trap = App->dancer_app->logger_engine->trapper;

    is_deeply $trap->read, [
        { level => 'debug', message => 'this is my debug message' },
        { level => 'info',  message => 'this is my info message' },
    ];

    is_deeply $trap->read, [];
};

done_testing;
