Dancer2::Test - Useful routines for testing Dancer2 apps

=head1 VERSION

version 0.207000

=head1 SYNOPSIS

    use Test::More;
    use Plack::Test;
    use HTTP::Request::Common; # install separately

    use YourDancerApp;

    my $app  = YourDancerApp->to_app;
    my $test = Plack::Test->create($app);

    my $res = $test->request( GET '/' );
    is( $res->code, 200, '[GET /] Request successful' );
    like( $res->content, qr/hello, world/, '[GET /] Correct content' );

=head1 DESCRIPTION

B<DEPRECATED. This module and all the functions listed below are deprecated. Do
not use this module.> The routines provided by this module for testing Dancer2
apps are buggy and unnecessary. Instead, use the L<Plack::Test> module as shown
in the SYNOPSIS above and ignore the functions in this documentation. Consult
the L<Plack::Test> documenation for further details.

This module will be removed from the Dancer2 distribution in the near future.
You should migrate all tests that use it over to the L<Plack::Test> module and
remove this module from your system. This module will throw warnings to remind
you.

For now, you can silence the warnings by setting the C<NO_WARN> option:

    $Dancer::Test::NO_WARN = 1;

In the functions below, $test_name is always optional.

=head1 FUNCTIONS

=head2 dancer_response ($method, $path, $params, $arg_env);

Returns a Dancer2::Core::Response object for the given request.

Only $method and $path are required.

$params is a hashref with 'body' as a string; 'headers' can be an arrayref or
a HTTP::Headers object, 'files' can be arrayref of hashref, containing some
files to upload:

    dancer_response($method, $path,
        {
            params => $params,
            body => $body,
            headers => $headers,
            files => [ { filename => '/path/to/file', name => 'my_file' } ],
        }
    );

A good reason to use this function is for testing POST requests. Since POST
requests may not be idempotent, it is necessary to capture the content and
status in one shot. Calling the response_status_is and response_content_is
functions in succession would make two requests, each of which could alter the
state of the application and cause Schrodinger's cat to die.

    my $response = dancer_response POST => '/widgets';
    is $response->status, 202, "response for POST /widgets is 202";
    is $response->content, "Widget #1 has been scheduled for creation",
        "response content looks good for first POST /widgets";

    $response = dancer_response POST => '/widgets';
    is $response->status, 202, "response for POST /widgets is 202";
    is $response->content, "Widget #2 has been scheduled for creation",
        "response content looks good for second POST /widgets";

It's possible to test file uploads:

    post '/upload' => sub { return upload('image')->content };

    $response = dancer_response(POST => '/upload', {files => [{name => 'image', filename => '/path/to/image.jpg'}]});

In addition, you can supply the file contents as the C<data> key:

    my $data  = 'A test string that will pretend to be file contents.';
    $response = dancer_response(POST => '/upload', {
        files => [{name => 'test', filename => "filename.ext", data => $data}]
    });

You can also supply a hashref of headers:

    headers => { 'Content-Type' => 'text/plain' }

=head2 response_status_is ($request, $expected, $test_name);

Asserts that Dancer2's response for the given request has a status equal to the
one given.

    response_status_is [GET => '/'], 200, "response for GET / is 200";

=head2 route_exists([$method, $path], $test_name)

Asserts that the given request matches a route handler in Dancer2's
registry. If the route would have returned a 404, the route still exists
and this test will pass.

Note that because Dancer2 uses the default route handler
L<Dancer2::Handler::File> to match files in the public folder when
no other route matches, this test will always pass.
You can disable the default route handlers in the configs but you probably
want L<Dancer2::Test/response_status_is> or L<Dancer2::Test/dancer_response>

    route_exists [GET => '/'], "GET / is handled";

=head2 route_doesnt_exist([$method, $path], $test_name)

Asserts that the given request does not match any route handler
in Dancer2's registry.

Note that this test is likely to always fail as any route not matched will
be handled by the default route handler in L<Dancer2::Handler::File>.
This can be disabled in the configs.

    route_doesnt_exist [GET => '/bogus_path'], "GET /bogus_path is not handled";

=head2 response_status_isnt([$method, $path], $status, $test_name)

Asserts that the status of Dancer2's response is not equal to the
one given.

    response_status_isnt [GET => '/'], 404, "response for GET / is not a 404";

=head2 response_content_is([$method, $path], $expected, $test_name)

Asserts that the response content is equal to the C<$expected> string.

 response_content_is [GET => '/'], "Hello, World",
        "got expected response content for GET /";

=head2 response_content_isnt([$method, $path], $not_expected, $test_name)

Asserts that the response content is not equal to the C<$not_expected> string.

    response_content_isnt [GET => '/'], "Hello, World",
        "got expected response content for GET /";

=head2 response_content_like([$method, $path], $regexp, $test_name)

Asserts that the response content for the given request matches the regexp
given.

    response_content_like [GET => '/'], qr/Hello, World/,
        "response content looks good for GET /";

=head2 response_content_unlike([$method, $path], $regexp, $test_name)

Asserts that the response content for the given request does not match the regexp
given.

    response_content_unlike [GET => '/'], qr/Page not found/,
        "response content looks good for GET /";

=head2 response_content_is_deeply([$method, $path], $expected_struct, $test_name)

Similar to response_content_is(), except that if response content and
$expected_struct are references, it does a deep comparison walking each data
structure to see if they are equivalent.

If the two structures are different, it will display the place where they start
differing.

    response_content_is_deeply [GET => '/complex_struct'],
        { foo => 42, bar => 24},
        "got expected response structure for GET /complex_struct";

=head2 response_is_file ($request, $test_name);

=head2 response_headers_are_deeply([$method, $path], $expected, $test_name)

Asserts that the response headers data structure equals the one given.

    response_headers_are_deeply [GET => '/'], [ 'X-Powered-By' => 'Dancer2 1.150' ];

=head2 response_headers_include([$method, $path], $expected, $test_name)

Asserts that the response headers data structure includes some of the defined ones.

    response_headers_include [GET => '/'], [ 'Content-Type' => 'text/plain' ];

=head2 route_pod_coverage()

Returns a structure describing pod coverage in your apps

for one app like this:

    package t::lib::TestPod;
    use Dancer2;

    =head1 NAME

    TestPod

    =head2 ROUTES

    =over

    =cut

    =item get "/in_testpod"

    testpod

    =cut

    get '/in_testpod' => sub {
        return 'get in_testpod';
    };

    get '/hello' => sub {
        return "hello world";
    };

    =item post '/in_testpod/*'

    post in_testpod

    =cut

    post '/in_testpod/*' => sub {
        return 'post in_testpod';
    };

    =back

    =head2 SPECIALS

    =head3 PUBLIC

    =over

    =item get "/me:id"

    =cut

    get "/me:id" => sub {
        return "ME";
    };

    =back

    =head3 PRIVAT

    =over

    =item post "/me:id"

    post /me:id

    =cut

    post "/me:id" => sub {
        return "ME";
    };

    =back

    =cut

    1;

route_pod_coverage;

would return something like:

    {
        't::lib::TestPod' => {
            'has_pod'             => 1,
            'routes'              => [
                "post /in_testpod/*",
                "post /me:id",
                "get /in_testpod",
                "get /hello",
                "get /me:id"
            ],
            'undocumented_routes' => [
                "get /hello"
            ]
        }
    }

=head2 is_pod_covered('is pod covered')

Asserts that your apps have pods for all routes

    is_pod_covered 'is pod covered'

to avoid test failures, you should document all your routes with one of the following:
head1, head2,head3,head4, item.

    ex:

    =item get '/login'

    route to login

    =cut

    if you use:

    any '/myaction' => sub {
        # code
    }

    or

    any ['get', 'post'] => '/myaction' => sub {
        # code
    };

    you need to create pods for each one of the routes created there.

=head2 import

When Dancer2::Test is imported, it should be passed all the
applications that are supposed to be tested.

If none passed, then the caller is supposed to be the sole application
to test.

    # t/sometest.t

    use t::lib::Foo;
    use t::lib::Bar;

    use Dancer2::Test apps => ['t::lib::Foo', 't::lib::Bar'];
