Test names should be more precise

[RalfKoban]

There are tests that are named like EventIsRaised or ExceptionThrown.

Those names are unspecific because they do not mention which event is raised or which exception is thrown.
Hence they should be improved to include that important information.

Following (incomplete) list may trigger an issue for events:

• EventRaised
• EventIsRaised
• IfEventIsRaised
• WhenEventIsRaised
• Event_Is_Raised
• If_Event_Is_Raised
• When_Event_Is_Raised
• RaisedEvent,
• RaisesEvent,
• Raised_Event,
• Raises_Event,
• EventOccurred
• EventOccured
• OccurredEvent
• OccuredEvent
• EventIsFired
• EventFired
• FiresEvent

Following (incomplete) list may trigger an issue for exceptions:

• ExceptionThrown
• ThrowsException
• exception_thrown
• throws_exception
