Test::HTTP::LocalServer - spawn a local HTTP server for testing

  use HTTP::Tiny;
  my $server = Test::HTTP::LocalServer->spawn(
      request_pause => 1, # wait one second before accepting the next request
  );
  my $res = HTTP::Tiny->new->get( $server->url );
  print $res->{content};
  $server->stop;

This module implements a tiny web server suitable for running "live" tests of HTTP clients against it. It also takes care of cleaning %ENV from settings that influence the use of a local proxy etc.

Use this web server if you write an HTTP client and want to exercise its behaviour in your test suite without talking to the outside world.

  my $server = Test::HTTP::LocalServer->spawn;

This spawns a new HTTP server. The server will stay running until

  $server->stop

is called. Ideally, you explicitly call "->stop" or use

  undef $server

before the main program ends so that the program exit code reflects the real exit code and not the chlid exit code.

Valid arguments are :

  • "html =>" scalar containing the page to be served

    If this is not specified, an informative default page will be used.

  • "request_pause =>" number of seconds to sleep before accepting the next request

    If your system is slow or needs to wait some time before a socket connection is ready again, use this parameter to make the server wait a bit before handling the next connection.

  • "file =>" filename containing the page to be served
  • "debug => 1" to make the spawned server output debug information
  • "eval =>" string that will get evaluated per request in the server

    Try to avoid characters that are special to the shell, especially quotes. A good idea for a slow server would be

      eval => sleep+10
        

All served HTML will have the first %s replaced by the current location.

The following entries will be removed from %ENV when making a request:

    HTTP_PROXY
    http_proxy
    HTTP_PROXY_ALL
    http_proxy_all
    HTTPS_PROXY
    https_proxy
    CGI_HTTP_PROXY
    ALL_PROXY
    all_proxy

This returns the port of the current server. As new instances will most likely run under a different port, this is convenient if you need to compare results from two runs.

This returns the URI where you can contact the server. This url is valid until the $server goes out of scope or you call

  $server->stop;

The returned object is a copy that you can modify at your leisure.

This returns the URI object of the server URL. Use "$server->url" instead. Use this object if you want to modify the hostname or other properties of the server object.

Consider this basically an emergency accessor. In about every case, using "->url()" does what you want.

This stops the server process by requesting a special url.

This kills the server process via "kill". The log cannot be retrieved then.

This returns the output of the server process. This output will be a list of all requests made to the server concatenated together as a string.

  my $url = $server->local('foo.html');
  # file:///.../foo.html

Returns an URL for a local file which will be read and served by the webserver. The filename must be a relative filename relative to the location of the current program.

  $server->content(<<'HTML');
      <script>alert("Hello World");</script>
  HTML

The URL will contain the HTML as supplied. This is convenient for supplying Javascript or special URL to your user agent.

This URL will send a file with a "Content-Disposition" header and indicate the suggested filename as passed in.

This URL will issue a redirect to $target. No special care is taken towards URL-decoding $target as not to complicate the server code. You need to be wary about issuing requests with escaped URL parameters.

This URL will issue a 401 basic authentication challenge. The expected user and password are encoded in the URL.

    my $challenge_url = $server->basic_auth('foo','secret');
    my $wrong_pw = URI->new( $challenge_url );
    $wrong_pw->userinfo('foo:hunter2');
    $res = HTTP::Tiny->new->get($wrong_pw);
    is $res->{status}, 401, "We get the challenge with a wrong user/password";

This URL will response with status code 404.

This URL will send a 599 error after $seconds seconds.

This URL will send nothing and close the connection after $seconds seconds.

This URL will send headers for a successful response but will close the socket with an error after 2 blocks of 16 spaces have been sent.

This URL will return 5 blocks of 16 spaces at a rate of one block per second in a chunked response.

This URL will return a short HTTP response that expands to 16M body.

This URL will return a short HTTP response that expands to 16M body.

All other URLs will echo back the cookies and query parameters.

None by default.
