=head1 NAME
Dancer2::Manual::Testing - Writing tests for Dancer2
=head1 VERSION
version 0.166001
=head1 Basic application testing
Since L<Dancer2> produces PSGI applications, you can easily write tests using
L<Plack::Test> and provide your Dancer application as the app for testing.
A basic test (which we also scaffold with L<dancer2>) looks like this:
use strict;
use warnings;
use Test::More tests => 4;
use Plack::Test;
use HTTP::Request::Common;
use_ok('MyApp');
# create an application
my $app = MyApp->to_app;
isa_ok( $app, 'CODE' );
# create a testing object
my $test = Plack::Test->create($app);
# now you can call requests on it and get responses
# requests are of HTTP::Request
# responses are of HTTP::Response
# "GET" from HTTP::Request::Common creates an HTTP::Request object
my $response = $test->request( GET '/' );
# same as:
# my $response = $test->request( HTTP::Request->new( GET => '/' ) );
ok( $response->is_success, 'Successful request' );
is( $response->content, 'OK', 'Correct response content' );
Read the documentation for L<HTTP::Request> and L<HTTP::Request::Common> to
see the different options for sending parameters.
=head1 Cookies
If you don't want to use an entire user agent for this test, you can use
L<HTTP::Cookies> to store cookies and then retrieve them:
use strict;
use warnings;
use Test::More tests => 3;
use Plack::Test;
use HTTP::Request::Common;
use HTTP::Cookies;
use_ok('MyApp');
my $url = 'http://localhost';
my $jar = HTTP::Cookies->new();
my $test = Plack::Test->create( MyApp->to_app );
subtest 'Create session' => sub {
my $res = $test->request( GET "$url/login" );
ok( $res->is_success, 'Successful login' );
# extract cookies from the response and store in the jar
$jar->extract_cookies($res);
};
subtest 'Check session' => sub {
my $req = GET "$url/logout";
# add cookies to the request
$jar->add_cookie_header($req);
my $res = $test->request($req);
ok( $res->is_success, 'Successful logout' );
like(
$res->content,
'Successfully logged out',
'Got correct log out content',
);
};
Please note that the request URL must include scheme and host for the call
to L<HTTP::Cookies/add_cookie_header> to work.
=head1 Plugins
In order to test plugins, you can create an application on the spot, as
part of the test script code, and use the plugin there.
use strict;
use warnings;
use Test::More tests => 2;
use Plack::Test;
use HTTP::Request::Common;
{
package MyTestApp;
use Dancer2;
use Dancer2::Plugin::MyPlugin;
get '/' => sub { my_keyword };
}
my $test = Plack::Test->create( MyTestApp->to_app );
my $res = $test->request( GET '/' );
ok( $res->is_success, 'Successful request' );
is( $res->content, 'MyPlugin-MyKeyword', 'Correct content' );
