How to add a "Test App" to an SDK Package for Testing purposes?

We currently have a production App as well as a Test App. The Test App is used solely for testing purposes and only contains the essential UI that we need to run the app.

Most of that data is obtained from a Package that we built in order to separate certain pieces of code into smaller chunks.

The problem that we are running into is that each time we update the package, we also have to update the Test App so that it uses the latest package version. So essentially each time we update the SDK, we also have to release a new Build for the Test App.

My question is is there a way to make our Test App a function of the SDK/Package, and not a separate app in order to avoid having to release multiple App builds with each Package update and in order to get unit/UI Testing automated?
