Solution 1:

Is the primary account on your test device the same as your Google Play developer account?

If not you won't get signatures on the android.test.* static responses unless the app has been published on Play before.

See the table at http://developer.android.com/guide/market/billing/billing_testing.html#static-responses-table for the full set of conditions.
