JUnit testing with SWF 2.0.7

[pkilpatrick]

Hello all,

I'm kind of new to Spring Web Flow, been playing around with it casually for around 6 - 8 months or so, and this is my first post here... glad to be part of this community!
Now I've just updated one of my applications from SWF 1.0.5 to 2.0.7 and I've just started trying to implement some unit testing into my application(had no previous unit testing).

Now I'm using JUnit as well. I've read through the webflow-reference pdf but to no avail.

I'm running the following unit test: (note: I've created a stub for my EJB calls as shown below)

protected FlowDefinitionResource getResource(FlowDefinitionResourceFactory resourceFactory) {
		return resourceFactory.createFileResource("web/WEB-INF/flow/resetPassword-flow.xml");
	}
	
	protected void configureFlowBuilderContext(MockFlowBuilderContext builderContext) {
	    builderContext.registerBean("ejbBean", new StubEjbBean());
	}

	protected FlowDefinitionResource[] getModelResources(FlowDefinitionResourceFactory resourceFactory) {
	   return new FlowDefinitionResource[] { resourceFactory.createFileResource("file:/src/test/applicationContext-flow-junit.xml"), resourceFactory.createFileResource("file:/src/test/applicationContext-junit.xml") };
	}

	public void testResetPasswordFlow() {

	    MutableAttributeMap input = new LocalAttributeMap();
	    MockExternalContext context = new MockExternalContext();
	    
	    startFlow(input, context);
	    
	    System.out.println("End of JUnit Test [testResetPasswordFlow]");
	}

and here is simple flow I'm trying to test

<?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
			    http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">
	
	<action-state id="initialFlowAction">
		<evaluate expression="initialFlowAction" />
		<transition on="success" to="resetPasswordUserId"/>
	</action-state>
<view-state id="resetPasswordUserId" view="resetPasswordUserId">
		<on-entry>
            <evaluate expression="resetPasswordUserForm.setupForm"/>
        </on-entry>
		<transition on="continue" to="finalView">
			<evaluate expression="resetPasswordUserForm.bindAndValidate"/>
		</transition>
	</view-state>

<end-state id="finalView" view="finalView"/>
</flow>

and finally this is the exception I get.

org.springframework.webflow.execution.ActionExecutionException: Exception thrown executing [AnnotatedAction@63fe63fe targetAction = [EvaluateAction@66006600 expression = initialFlowAction, resultExposer = [null]], attributes = map[[empty]]] in state 'initialFlowAction' of flow 'resetPassword-flow' -- action execution attributes were 'map[[empty]]'

Any help would be greatly appreciated. Thanks guys.

Hey all,
I've just upped the logging on org.springframework.level to ALL and this is the result I get.

Am I meant to be putting something into the 'action execution attributes'?

[sivaram.psg]

I guess you can try giving mock values to your Flow Scope or any scope variables when u start the flow..

something like this
MutableAttributeMap input = new LocalAttributeMap();
input.put("initialFlowActionResult", "any value you wish");
then start flow with
startFlow(input, context);
