No data is sent to WorldPay

Attempting to send a purchase to WorldPay results in a PurchaseResponse object being returned seemingly without any attempt being made to contact WorldPay servers?

Here's the code:

            $gateway = Omnipay::create('WorldPay');
            $gateway->setInstallationId('123456');
            $gateway->setTestMode(true);

            $data = array(
                'amount'    => '10.00',
                'card'      => array(
                    'cvv'         => '123',
                    'expiryMonth' => '6',
                    'expiryYear'  => '2016',
                    'number'      => '4242424242424242'
                ),
                'currency'  => 'GBP',
                'returnUrl' => 'http://returnurl.dev'
            );
            $response = $gateway->purchase($data)->send();

A look through the code for the plugin shows no access being attempted to WorldPay servers. What am I missing?

You're not missing anything. Worldpay doesn't require any server to server communication, the data is sent as query parameters by the client.

Following the omnipay conventions, it returns a redirect response. You can call $response->isRedirect() and $response->redirect() to send your customer to Worldpay with the correct URL.
