Spring WebFlow(3)JUnit Test

Spring WebFlow(3)JUnit Test

sample class for a normal webflow:
package org.springframework.webflow.samples.booking;

import org.easymock.EasyMock;
import org.springframework.webflow.config.FlowDefinitionResource;
import org.springframework.webflow.config.FlowDefinitionResourceFactory;
import org.springframework.webflow.core.collection.LocalAttributeMap;
import org.springframework.webflow.core.collection.MutableAttributeMap;
import org.springframework.webflow.test.MockExternalContext;
import org.springframework.webflow.test.MockFlowBuilderContext;
import org.springframework.webflow.test.execution.AbstractXmlFlowExecutionTests;

public class BookingFlowExecutionTests extends AbstractXmlFlowExecutionTests {

private BookingService bookingService;

protected void setUp() {
bookingService = EasyMock.createMock(BookingService.class);
}

@Override
protected FlowDefinitionResource getResource(FlowDefinitionResourceFactory resourceFactory) {
return resourceFactory.createFileResource("src/main/webapp/WEB-INF/hotels/booking/booking-flow.xml");
}

@Override
protected void configureFlowBuilderContext(MockFlowBuilderContext builderContext) {
builderContext.registerBean("bookingService", bookingService);
}

public void testStartBookingFlow() {
Booking booking = createTestBooking();

EasyMock.expect(bookingService.createBooking(1L, "keith")).andReturn(booking);

EasyMock.replay(bookingService);

MutableAttributeMap input = new LocalAttributeMap();
input.put("hotelId", "1");
MockExternalContext context = new MockExternalContext();
context.setCurrentUser("keith");
startFlow(input, context);

assertCurrentStateEquals("enterBookingDetails");
assertResponseWrittenEquals("enterBookingDetails", context);
assertTrue(getRequiredFlowAttribute("booking") instanceof Booking);

EasyMock.verify(bookingService);
}

public void testEnterBookingDetails_Proceed() {
setCurrentState("enterBookingDetails");
getFlowScope().put("booking", createTestBooking());

MockExternalContext context = new MockExternalContext();
context.setEventId("proceed");
resumeFlow(context);

assertCurrentStateEquals("reviewBooking");
assertResponseWrittenEquals("reviewBooking", context);
}

public void testReviewBooking_Confirm() {
setCurrentState("reviewBooking");
getFlowScope().put("booking", createTestBooking());
MockExternalContext context = new MockExternalContext();
context.setEventId("confirm");
resumeFlow(context);
assertFlowExecutionEnded();
assertFlowExecutionOutcomeEquals("bookingConfirmed");
}

private Booking createTestBooking() {
Hotel hotel = new Hotel();
hotel.setId(1L);
hotel.setName("Jameson Inn");
User user = new User("keith", "pass", "Keith Donald");
Booking booking = new Booking(hotel, user);
return booking;
}

}

The configuration in flow.xml:
<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">

<secured attributes="ROLE_USER" />

<input name="hotelId" required="true" />

<on-start>
<evaluate expression="bookingService.createBooking(hotelId, currentUser.name)" result="flowScope.booking" />
</on-start>

<view-state id="enterBookingDetails" model="booking">
<binder>
<binding property="checkinDate" />
<binding property="checkoutDate" />
<binding property="beds" />
<binding property="smoking" />
<binding property="creditCard" />
<binding property="creditCardName" />
<binding property="creditCardExpiryMonth" />
<binding property="creditCardExpiryYear" />

</binder>
<on-render>
<render fragments="body" />
</on-render>
<transition on="proceed" to="reviewBooking" />
<transition on="cancel" to="cancel" bind="false" />
</view-state>

<view-state id="reviewBooking" model="booking">
<on-render>
<render fragments="body" />
</on-render>
<transition on="confirm" to="bookingConfirmed">
<evaluate expression="bookingService.persistBooking(booking)" />
</transition>
<transition on="revise" to="enterBookingDetails" />
<transition on="cancel" to="cancel" />
</view-state>
<end-state id="bookingConfirmed"/>
<end-state id="cancel" />
</flow>

I failed to inverstigate this base on subflow.
