Description

If the engine within the testcontainer is not started and we try to communicate with it we get the following exception:

2022-04-25 10:20:03.631  WARN 6632 --- [ault-executor-0] io.camunda.zeebe.client.job.poller       : Failed to activate jobs for worker test1 and job type test1

Instead of this unknown exception we should mention that the engine is currently not running and that the start() method should be called first.

[!Note] Heads up! We are building a new Java testing library for Camunda 8.6. The new library will replace Zeebe Process Test. Read more about upcoming changes here and stay tuned for updates. :rocket:
