Apparently you are not a software engineer then. You can test various
functions in the engine for expected results. Put in a position and run a
unit test to determine certain expected results in that position (i.e. certain
moves are always good). Yes, it is possible to put unit testing around that
chess engine ... you just need to put in the hooks and debug.

So we cannot test all the moves I think there are more moves possible
than all the dust particles in the World.


Nobody said anything about testing all moves. I said make some unit tests
that can stress various functions in your engine. Then at least, you will
know those functions are working as expected under certain test conditions.
