The condition can be signalled by an event. For example, event t2:b
might indicate that task t2 did not manage to produce expected result, so
we do not need to run task t4.
complete rather than running it.
complete expression evaluation takes precedence over the trigger.
Completes can be between tasks, between families, or both.

What to do:
- Update test.def or test.py to add a complete expression to task t4
- Replace the suite
- Observe the tasks in ecflowview
- See the triggers by selecting t4 and clicking on the icon
- See the trigger relation by clicking on the arrow
- See the triggers in the tree, using the Show menu
- Note the icon indicating that the task has not run
- You can modify task t2 to check that task t4 will run when the event is not set
