Question

在我的BPMN中，我在执行监听器中设置了一个变量，如Internal Context Variables中所述：

下面的示例显示一个表达式，该表达式将变量test设置为执行侦听器的当前事件名称。
<camunda:executionListener event="start"
 expression="${execution.setVariable('test', execution.eventName)}" />

我尝试在Camunda Spring Boot应用程序的JUnit测试中测试此BPMN，但未应用执行侦听器。

BPMN：

  <bpmn:process id="test_bpmn" isExecutable="true">
    <bpmn:startEvent id="StartEvent_1">
      <bpmn:extensionElements>
        <camunda:executionListener expression="execution.setVariable(&#34;test&#34;, &#34;success&#34;)" event="start" />
      </bpmn:extensionElements>
      <bpmn:outgoing>SequenceFlow_0hgrhd2</bpmn:outgoing>
    </bpmn:startEvent>
    <bpmn:sequenceFlow id="SequenceFlow_0hgrhd2" sourceRef="StartEvent_1" targetRef="Task_11dxb5y" />
    <bpmn:userTask id="Task_11dxb5y">
      <bpmn:incoming>SequenceFlow_0hgrhd2</bpmn:incoming>
    </bpmn:userTask>
  </bpmn:process>

JUnit测试：

@Deployment(resources = {"test.bpmn"})
public class MyTest {

    @Rule
    public ProcessEngineRule rule = new StandaloneInMemoryTestConfiguration().rule();

    @Test
    public void test() {

    ProcessInstance instance = rule.getRuntimeService().startProcessInstanceByKey("test_bpmn");
    assertThat(instance).isActive().hasVariables("test");
}

错误：

java.lang.AssertionError: Expecting actual ProcessInstance {id='4', processDefinitionId='test_bpmn:1:3', businessKey='null'} to hold process variables [test], instead we found it to hold no variables at all.

我错了什么？

如何在Camunda Spring Boot应用程序中使用执行侦听器测试BPMN？
