NAME

Dancer2::Manual::Testing - Writing tests for Dancer2

CONTENTS

VERSION

version 0.166001

Basic application testing

Since Dancer2 produces PSGI applications, you can easily write tests using Plack::Test and provide your Dancer application as the app for testing.

A basic test (which we also scaffold with 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 HTTP::Request and HTTP::Request::Common to see the different options for sending parameters.

Cookies

If you don’t want to use an entire user agent for this test, you can use 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 add_cookie_header in HTTP::Cookies to work.

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 );
