如何使用输入参数测试Grails webflow？

Question

我正在为Webflow编写测试，我有一个webflow（A）在执行期间调用另一个webflow（子webflow）（B）。如果A呼叫B，它总是通过呼叫声明所需的参数/输入。单独测试A不是问题，但我如何自己测试B？输入参数的状态为：

input {
    station(required: true)
}

我尝试从startFlow（）开始，但这给了我以下异常：

Failure: testCreateWizardSubSubFlow(com.lstelcom.spectraweb.data.EquipmentFlowTests)
org.springframework.webflow.engine.FlowInputMappingException: 
Errors occurred during input mapping on startup of the 'createWizardSubSub' flow;
    errors = [[RequiredError@51a9e7fc mapping = station -> station, code = 'required', error = true, errorCause = [null], originalValue = [null], mappedValue = [null]]]    
at grails.test.WebFlowTestCase.startFlow(WebFlowTestCase.groovy:130)
at com.lstelcom.spectraweb.data.EquipmentFlowTests.testCreateWizardSubSubFlow(EquipmentFlowTests.groovy:38)

由于我收到错误，WebFlowTestCase中不存在带有输入参数的startFlow方法调用（例如，startFlow（new Station（）））：

groovy.lang.MissingMethodException: No signature of method: com.lstelcom.spectraweb.data.EquipmentFlowTests.startFlow() is applicable for argument types: (com.lstelcom.spectraweb.data.stations.Station) values: []
Possible solutions: getFlow(), getFlow()
    at com.lstelcom.spectraweb.data.EquipmentFlowTests.testCreateWizardSubSubFlow(EquipmentFlowTests.groovy:38)

所以问题是如何使用输入参数测试webflow？
