There is chalengge mode for that actually since the very first version of BC. You can play it for free (0 energy), the first squirrel spawned can take like half hour before it could take out your base so you can stock out money while letting that squirrel keep hitting your base then go cannon and spawn the unit you wanted to test to hit the base and see the damage done.

Now we also got the catclaw dojo as well.
