This is the right approach -- perhaps there is a bug in your code
somewhere?  Without seeing your code, it's hard to know where the
problem is.  Start with a minimal product, see below) and try to
import that.  You can grow from there.

If you restart Zope, the product should reappear, as far as I know.
As for working with test code, if you put a file called refresh.txt in
your product dir, you can reload your product from the manager
interface without restarting zope.

3 very helpful resources for this, the maxm minimal product guides:

and Chapter 4 of the Zope Developer's guide:
