Many users have a strange imagination about programmer's engine testing.
They think it is an issue of counting games won, lost or drawn.

A programmer's testing has mostly  to do with gathering and analyzing
statistics related with innumerable internal engine tricks and secrets,
e.g.

a) how frequently does the time management trick fail ?
b) how frequently could SEE safely replace QSearch ?
c) how high is the NullMove efficiency ?
d) how risky is the new pruning trick ?
e) ... etc
Beta testers can't help with the above.

After all this, tying it up and the testing overall playing strength from
user's view (using beta testers) is less time consuming.
