NAME
Plack::Test - Test PSGI applications with various backends
SYNOPSIS
use Plack::Test; # named params test_psgi app => sub { my $env = shift; return [ 200, [ 'Content-Type' => 'text/plain' ], [ "Hello World" ] ], }, client => sub { my $cb = shift; my $req = HTTP::Request->new(GET => "http://localhost/hello"); my $res = $cb->($req); like $res->content, qr/Hello World/; }; use HTTP::Request::Common; # positional params (app, client) my $app = sub { return [ 200, [], [ "Hello "] ] }; test_psgi $app, sub { my $cb = shift; my $res = $cb->(GET "/"); is $res->content, "Hello"; };
DESCRIPTION
Plack::Test is a unified interface to test PSGI applications using HTTP::Request and HTTP::Response objects. It also allows you to run PSGI applications in various ways. The default backend is "Plack::Test::MockHTTP", but you may also use any Plack::Handler implementation to run live HTTP requests against at web server
FUNCTIONS
test_psgi test_psgi $app, $client; test_psgi app => $app, client => $client; Runs the client test code $client against a PSGI application $app. The client callback gets one argument $cb, a callback that accepts an "HTTP::Request" object and returns an "HTTP::Response" object. Use HTTP::Request::Common to import shortcuts for creating requests for "GET", "POST", "DELETE", and "PUT" operations. For your convenience, the "HTTP::Request" given to the callback automatically uses the HTTP protocol and the localhost (127.0.0.1 by default), so the following code just works: use HTTP::Request::Common; test_psgi $app, sub { my $cb = shift; my $res = $cb->(GET "/hello"); }; Note that however, it is not a good idea to pass an arbitrary (i.e. user-input) string to "GET" or even "HTTP::Request->new" by assuming that it always represents a path, because: my $req = GET "//foo/bar"; would represent a request for a URL that has no scheme, has a hostname foo and a path /bar, instead of a path //foo/bar which you might actually want.
OPTIONS
Specify the Plack::Test backend using the environment variable "PLACK_TEST_IMPL" or $Plack::Test::Impl package variable. The available values for the backend are: MockHTTP (Default) Creates a PSGI env hash out of HTTP::Request object, runs the PSGI application in-process and returns HTTP::Response. Server Runs one of Plack::Handler backends ("Standalone" by default) and sends live HTTP requests to test. ExternalServer Runs tests against an external server specified in the "PLACK_TEST_EXTERNALSERVER_URI" environment variable instead of spawning the application in a server locally. For instance, test your application with the "HTTP::Server::ServerSimple" server backend with: > env PLACK_TEST_IMPL=Server PLACK_SERVER=HTTP::Server::ServerSimple prove -l t/test.t
