Activiti process timer DB entry

Hi All,We have a scenario to notify the user with some message after 30 days. We have used the below code to initiate the timer: <boundaryEvent id="timer1" name="Timer1" attachedToRef="subProcess" cancelActivity="false"> <timerEventDefinition> <timeDuration>P

There are a lot of possibilities. What kind of tests do you want to run?

One proposal could be to use simulation and move process execution into virtual time. In that case you can achieve 30d delay independently from real time. Simulation framework: http://gro-mar.github.io/activiti-crystalball/

As per my understanding, when a workflow is initiated by processEngine, a DB entry to ACT_HI_PROCINST is made. Similarly for the timer if i change the creation date then the alert shown after 30 days can be tweaked.

Can somebody help us out with the DB table where the timer task is added?

Could following jUnit test help you?

  public void testInterruptingTimerDuration() {
    
    // Start process instance
    ProcessInstance pi = runtimeService.startProcessInstanceByKey("escalationExample");

    // There should be one task, with a timer : first line support
    Task task = taskService.createTaskQuery().processInstanceId(pi.getId()).singleResult();
    assertEquals("First line support", task.getName());

    // Manually execute the job
    Job timer = managementService.createJobQuery().singleResult();
    managementService.executeJob(timer.getId());

    // The timer has fired, and the second task (secondlinesupport) now exists
    task = taskService.createTaskQuery().processInstanceId(pi.getId()).singleResult();
    assertEquals("Handle escalated issue", task.getName());
