[dancer-users] Dancer2: Create a configuration for testing

I have a Dancer2 app.
I want to test it properly against a database.
For every test run I create a new database and a new empty schema
My new database has a random name (e.g. app_123abc) and at the end of
the test I drop the database.

How can I change the Dancer2 app configuration during the test run, or
before I do
my $test = Plack::Test->create( $app );

As it is, is just loads the config files for development. I want to
provide my own configuration programmatically. Creating files in the
current directory is not an option.

I have tried:
config->{'my_stuff'} = \%my_stuff
set 'my_stuff' => \%my_stuff

but Dancer2 doesn't seems to pick it up or it gets overwritten later by
the config from the files.


## no critic (Modules::ProhibitMultiplePackages)
use strict;
use warnings;
use 5.014; # JSON::PP included in CORE.

package ConfigChangeTest;
use Dancer2;
set serializer => 'JSON';
get qr{/info}msx => sub {
    return { appname => config->{'appname'}, };

package main;

use Test2::V0 -srand => time, qw(:DEFAULT);
use Plack::Test;

use HTTP::Request;
use JSON;
use Dancer2;

my $appname = 'ConfigChangeTest';
set appname => $appname;

my $test = Plack::Test->create( ConfigChangeTest->to_app );
my $req = HTTP::Request->new( GET => '/api/1/info' );
my $res = $test->request( $req );

ok( $res->is_success, 'Is success' );

# Fails!
# appname is the one set in the file `environments/development.yml` or
+ file `config.yml`.
is( decode_json $res->content, { appname => $appname, }, 'Is right con
+tent' );
