Test class Null safety

The top level object for an ROHD-VF test.

The Test contains references to the environment and the device under test (DUT), and also is responsible for kicking off sequences on appropriate sequencers.

Only one Test should be created per simulation run.



Test(String name, {int? randomSeed})
Constructs a new Test named name.
