Spring Web Flow - How can I set up unit test with values already in conversationScope?

Question

I am working on a project using Spring Web Flow 2.0.

I am trying to unit test a flow that begins with a decision state. The decision state checks the value of an object

Answer 1

It's not obvious, but I came up with this:

public void testFoo() {
    FlowExecution flowExecution = getFlowExecutionFactory().createFlowExecution(getFlowDefinition());
    updateFlowExecution(flowExecution);
    flowExecution.getConversationScope().put("fooBar", "goo");
    flowExecution.start(null, new MockExternalContext());        
    assertCurrentStateEquals("fooView");
}

I had to dig into the underlying AbstractXmlFlowExecutionTests.startFlow() to see how it was instantiating the FlowExecution, and copy and paste some of that into the unit test.

Here's the test web flow.

<?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="decideFoo">
        <evaluate expression="conversationScope.fooBar" />
        <transition on="goo" to="fooView" />
        <transition on="gar" to="barView" />
    </action-state>

    <view-state id="fooView" />

    <view-state id="barView" />

</flow>
