In my BPMN I set a variable in an execution listener as documented in Internal Context Variables:
The following example shows an expression which sets the variable test to the current event name of an execution listener.
<camunda:executionListener event="start" expression="${execution.setVariable('test', execution.eventName)}" />
I try to test this BPMN in a JUnit test of a Camunda Spring Boot application, but the execution listener is not applied.
BPMN:
<bpmn:process id="test_bpmn" isExecutable="true">
<bpmn:startEvent id="StartEvent_1">
<bpmn:extensionElements>
<camunda:executionListener expression="execution.setVariable("test", "success")" 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 test:
@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");
}
Error:
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.

What did I wrong?
