NAME

       Dancer2::Logger::Capture - Capture dancer logs

VERSION

       version 0.205002

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.

       It's 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;
