Thanks! This would soon appear, as-is, on its
appropriate Wiki.

All GUI Toolkits are different, but all use a similar
event driver system, huh?

Can you run processEvents in a loop?

You need it for the next step:

 - Temporary Interactive Test

That means, while the window is revealed, you click on
it and see what happens. Maybe you invoke a breakpoint
or a trace statement.

But you immediately convert what you learn into either
a test that simulates a user, or a test fixture - if
it's complex. Frequently comparing your simulations to
the real thing lets you catch situations where the
simulation behaves differently from the real thing.
