Can the "theory" of evolution even muster a hypothesis?

For several years I have been asking for a testable hypothesis for evolution via an accumulation of random mutations- ie genetic accidents.

The best I have seen so far only include hypotheses for descent with modification minus the mechanism.

And in each case I was able to take the hypothesis and turn it so that it supported ID or convergent evolution. That is why a testable hypothesis for the stated mechanism is key.

Any takers?
