JUnit: execution does not exist

Hi, I have created my first process as a copy of the groovy examples and when I run the JUnit test with the code

  @Deployment
  public void testMyProcess() {
     
    int[] inputArray = new int[] {1, 2, 3, 4, 5};
    ProcessInstance pi = runtimeService.startProcessInstanceByKey("myProcess", CollectionUtil.singletonMap("inputArray", inputArray));

    for (Execution execution : runtimeService.createExecutionQuery().list()) {
       System.out.println(String.format("[EXECUTION %s] %s", execution.getId(), execution.getProcessInstanceId()));
    }
    
    Integer result = (Integer) runtimeService.getVariable(pi.getId(), "y");
    assertEquals(2, result.intValue());
  }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

it fails with

which is correct because

runtimeService.createExecutionQuery().list()‍

does not pass anything back.

My question is if I did miss a setting to keep the process alive (I copied all the files from the groovy example and just changed
created a new process myself)?

P.S. sorry for asking that simple questions, I am new to the topic

Does your process have any 'wait' states in it?

If your process runs from start -> end with only automatic steps, then there will be no runtime process instances (nor executions) in the database (since your process is already done).
