@Override

A non-parametric feature (test) that only has a single "iteration".
Contrary to parametric tests - where the iterations are the children - this is the actual test. The execution
is only delegated, but does not cause any extra test events for the single iteration.
<p>
All node events are also delegated to the {@link IterationNode} in the correct order.
