DESCRIPTION

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

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

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

See Mojolicious::Guides::Testing for more.

ATTRIBUTES

Test::Mojo implements the following attributes.

handler

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

A callback to connect Test::Mojo with Test::More.

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

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]});

success

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

True if the last test was successful.

# Build custom tests
my $location_is = sub ($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!' });

tx

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

# 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';

ua

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