无法为webFlow 2.0.0运行Grails集成测试

我正在使用Grails2.0.3和webFlow 2.0.0

我的控制器中有一个WebFlow定义，它工作得很好，但我仍然希望添加集成测试，以便于将来的维护

每当控制器试图向流范围添加一些值时，我在测试中遇到以下异常：

ERROR org.codehaus.groovy.grails.webflow.engine.builder.ClosureInvokingAction  - Exception occured invoking flow action: No such property: poInfo for class: org.springframework.webflow.core.collection.LocalAttributeMap

这是我尝试测试的WebFlow代码的一部分：

def createFlow = { 
    initialize { 
        action { 
            if (params.eventId) { 
                flow.receivingEventId = params.eventId as int 
                ReceivingEvent existingReceivingEvent = ReceivingEvent.get(flow.receivingEventId) 
                flow.receivingEvent = new ReceivingEvent(branch:existingReceivingEvent.branch) 
            } 
        } 
        on ("success").to "addPO" 
    } 

    addPO { 
        on("add") { 
            log.debug("addPO") 
            // Initialize flow objects 
            flow.poInfo = new PoInfo(params) 
            if (flow.receivingEvent == null) { 
                flow.receivingEvent = new ReceivingEvent() 
            } 

            // validate and populate poInfo object 
            boolean objectIsValid = flow.poInfo.validateAndPopulate() 
            if(!objectIsValid) { 
                if(!flow.poInfo.hasErrors()) { 
                    flash.warning = 'poInfo.poNumber.unknown' 
                } 
                return error() 
            } 
            // add poInfo object to receivingEvent for additional processing/validation 
            String errorMessage = flow.receivingEvent.addPoInfo(flow.poInfo) 

            if(null != errorMessage) { 
                flash.warning = errorMessage 
                return error() 
            } else { 
                flow.poInfo = null 
            } 
        }.to("addPO")

这是我的集成测试：

class ReceivingEventCreationFlowTests extends WebFlowTestCase{ 

ReceivingEventController receivingEventController = new ReceivingEventController() 

void testInitializeFlow() { 
    startFlow() 
    assertCurrentStateEquals "addPO" 
} 

void testAddPoInfoMissingPiecesPallets() { 
    println("Hola mundo") 
    startFlow() 
    assertCurrentStateEquals "addPO" 

    receivingEventController.params.poNumber = '63055024UI1063' 
    receivingEventController.params.pro = '3' 
    println "flow scope: " + getFlowScope().getClass() 
    println ("Hola again") 
    signalEvent('add') 
    assertTrue getFlowScope().poInfo.hasErrors() 
    assertCurrentStateEquals "addPO" 
} 

@Override 
public Object getFlow() { 
    receivingEventController.createFlow 
} 

String getFlowId() { "create" } 
}

有人知道我错过了什么吗？或者webFlow 2.0.0和grails 2.0.3是否存在任何已知的集成测试问题

我遵循《Grails在行动》一书中的指导原则，第9.4章：测试WebFlows。。。然而，我不断地得到上面的错误

提前感谢,

豪尔赫·瓦斯奎兹（Jorge Vasquez）

圣杯行动（Grails in Action）是一本非常好的书，但有些陈旧。我建议您使用单元测试而不是集成测试。文档几乎不存在，但您可以在grails源代码中看到一个很好的示例：

您可以看到包含输入、输出、子流等的WebFlow（输入和输出比GIA书籍更新）

在Roeche使用对话范围的示例中，您可以改为使用流范围。

链接当前已关闭。是的，我的新建议：不要使用webflow。它是有缺陷的，没有文档记录。看起来这可能是当前的链接：
