Plack::App::Proxy::Test - Is utilities to test Plack::App::Proxy.
=head1 SYNOPSIS
test_proxy(
app => $backend_app,
proxy => sub { Plack::App::Proxy->new(remote => "http://$_[0]:$_[1]") },
client => sub {
my $cb = shift;
my $res = $cb->(GET '/');
ok $res->is_success, "Check the status line.";
},
);
=head1 DESCRIPTION
Plack::App::Proxy::Test provids test_proxy function which wraps
test_psgi of Plack::Test simply.
=head1 FUNCTIONS
=over 4
=item test_proxy
test_proxy app => $app,
proxy => $proxy_cb->($app_host, $app_port),
client => $client_cb->($cb);
=back
test_proxy runs two servers, 'C<app>' as an origin server and the proxy server.
In 'C<proxy>' callback, you should create the proxy server instance to send
requests to 'C<app>' server. Then 'C<client>' callback is called to run your
tests. In 'C<client>' callback, all HTTP requests are sent to 'C<proxy>'
server. (And the proxy server will proxy your request to the app server.)
