Utilities

There are different utilities that can help you to write your process test.

Manipulate the clock

The Camunda runtime uses an internal clock to execute process instances and to calculate when a BPMN timer event is due. In a test, you can use CamundaProcessTestContext to manipulate the clock.

When to use it:

  • Trigger an active BPMN timer event
  • Test scenarios that require a specific date or time, for example, a leap year
@Test
void shouldTriggerTimerEvent() {
// given: a process instance waiting at a BPMN timer event

// when
assertThat(processInstance).hasActiveElements("Wait 2 days");

processTestContext.increaseTime(Duration.ofDays(2));

// then
assertThat(processInstance).hasCompletedElements("Wait 2 days");
}
