How can I place a order by test details

[urfusion]

I am working on magento 1.9.1 and want to ask you that how I place a order in test mode.

I have replaced the details with the test details that you provided in your WP plugin. but after that It take me to a page where many banks are listed. I am confused.

What to do?

One more thing when I use your plugin then I am not able to capture the payment by my observer
her is my observer code

   public function implementOrderStatus($observer) {

        $order = $observer->getEvent()->getOrder();

        $orders = Mage::getModel('sales/order_invoice')->getCollection()
                ->addAttributeToFilter('order_id', array('eq' => $order->getId()));
        $orders->getSelect()->limit(1);

        if ((int) $orders->count() !== 0) {
            return $this;
        }

        if ($order->getState() == Mage_Sales_Model_Order::STATE_NEW) {

            try {
                if (!$order->canInvoice()) {
                    $order->addStatusHistoryComment('Inchoo_Invoicer: Order cannot be invoiced.', false);
                    $order->save();
                }

                //START Handle Invoice
                $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice();

                $invoice->setRequestedCaptureCase(Mage_Sales_Model_Order_Invoice::CAPTURE_OFFLINE);
                $invoice->register();

                $invoice->getOrder()->setCustomerNoteNotify(false);
                $invoice->getOrder()->setIsInProcess(true);
                $order->addStatusHistoryComment('Automatically INVOICED by Inchoo_Invoicer.', false);

                $transactionSave = Mage::getModel('core/resource_transaction')
                        ->addObject($invoice)
                        ->addObject($invoice->getOrder());

                $transactionSave->save();
                //END Handle Invoice
                //START Handle Shipment
                $shipment = $order->prepareShipment();
                $shipment->register();

                $order->setIsInProcess(true);
                $order->addStatusHistoryComment('Automatically SHIPPED by Inchoo_Invoicer.', false);

                $transactionSave = Mage::getModel('core/resource_transaction')
                        ->addObject($shipment)
                        ->addObject($shipment->getOrder())
                        ->save();
                //END Handle Shipment
                $order->setState(Mage_Sales_Model_Order::STATE_COMPLETE, true);
                $order->save();
            } catch (Exception $e) {
                $order->addStatusHistoryComment('Inchoo_Invoicer: Exception occurred during automaticallyInvoiceShipCompleteOrder action. Exception message: ' . $e->getMessage(), false);
                $order->save();
            }
        }

        return $this;
    }
