=head1 DESCRIPTION

L<Test::Mojo> is a test user agent based on L<Mojo::UserAgent>, it is usually
used together with L<Test::More> to test L<Mojolicious> applications. Just run
your tests with L<prove>.

  $ prove -l -v
  $ prove -l -v t/foo.t

If it is not already defined, the C<MOJO_LOG_LEVEL> environment variable will
be set to C<debug> or C<fatal>, depending on the value of the
C<HARNESS_IS_VERBOSE> environment variable. And to make it esier to test
HTTPS/WSS web services L<Mojo::UserAgent/"insecure"> will be activated by
default for L</"ua">.

See L<Mojolicious::Guides::Testing> for more.

=head1 ATTRIBUTES

L<Test::Mojo> implements the following attributes.

=head2 handler

  my $cb = $t->handler;
  $t     = $t->handler(sub {...});

A callback to connect L<Test::Mojo> with L<Test::More>.

  $t->handler(sub {
    my ($name, @args) = @_;
    return Test::More->can($name)->(@args);
  });

=head2 message

  my $msg = $t->message;
  $t      = $t->message([text => $bytes]);

Current WebSocket message represented as an array reference containing the
frame type and payload.

  # More specific tests
  use Mojo::JSON qw(decode_json);
  my $hash = decode_json $t->message->[1];
  is ref $hash, 'HASH', 'right reference';
  is $hash->{foo}, 'bar', 'right value';

  # Test custom message
  $t->message([binary => $bytes])
    ->json_message_has('/foo/bar')
    ->json_message_hasnt('/bar')
    ->json_message_is('/foo/baz' => {yada => [1, 2, 3]});

=head2 success

  my $bool = $t->success;
  $t       = $t->success($bool);

True if the last test was successful.

  # Build custom tests
  my $location_is = sub {
    my ($t, $value, $desc) = @_;
    $desc ||= "Location: $value";
    local $Test::Builder::Level = $Test::Builder::Level + 1;
    return $t->success(is($t->tx->res->headers->location, $value, $desc));
  };
  $t->get_ok('/')
    ->status_is(302)
    ->$location_is('https://mojolicious.org')
    ->or(sub { diag 'Must have been Joel!' });

=head2 tx

  my $tx = $t->tx;
  $t     = $t->tx(Mojo::Transaction::HTTP->new);

Current transaction, usually a L<Mojo::Transaction::HTTP> or
L<Mojo::Transaction::WebSocket> object.

  # More specific tests
  is $t->tx->res->json->{foo}, 'bar', 'right value';
  ok $t->tx->res->content->is_multipart, 'multipart content';
  is $t->tx->previous->res->code, 302, 'right status';

=head2 ua

  my $ua = $t->ua;
  $t     = $t->ua(Mojo::UserAgent->new);

User agent used for testing, defaults to a L<Mojo::UserAgent> object.

  # Allow redirects
  $t->ua->max_redirects(10);
  $t->get_ok('/redirect')->status_is(200)->content_like(qr/redirected/);

  # Switch protocol from HTTP to HTTPS
  $t->ua->server->url('https');
  $t->get_ok('/secure')->status_is(200)->content_like(qr/secure/);

  # Use absolute URL for request with Basic authentication
  my $url = $t->ua->server->url->userinfo('sri:secr3t')->path('/secrets.json');
  $t->post_ok($url => json => {limit => 10})
    ->status_is(200)
    ->json_is('/1/content', 'Mojo rocks!');

  # Customize all transactions (including followed redirects)
  $t->ua->on(start => sub {
    my ($ua, $tx) = @_;
    $tx->req->headers->accept_language('en-US');
  });
  $t->get_ok('/hello')->status_is(200)->content_like(qr/Howdy/);

=head1 METHODS

L<Test::Mojo> inherits all methods from L<Mojo::Base> and implements the
following new ones.

=head2 app

  my $app = $t->app;
  $t      = $t->app(Mojolicious->new);

Access application with L<Mojo::UserAgent::Server/"app">.

  my $c = $t->app->build_controller;
  ok $c->render(template => 'foo'), 'rendering was successful';
  is $c->res->status, 200, 'right status';
  is $c->res->body, 'Foo!', 'right content';

  # Change application behavior
  $t->app->hook(before_dispatch => sub {
    my $c = shift;
    $c->render(text => 'This request did not reach the router.')
      if $c->req->url->path->contains('/user');
  });
  $t->get_ok('/user')->status_is(200)->content_like(qr/not reach the router/);

  # Extract additional information
  my $stash;
