Try to find some tutorials, articles about unit testing SQLite database in Java. Unit Testing in Java and Android is certainly the same.

Although you would find these topics on Stack:

How to test Android sqlite with junit?

How to test methods that deal with SQLite database in android?

or this article:

Android Easy SQLite With Unit Tests

According to testing SQLite databese with Junit, check this:

Android JUnit test for SQLiteOpenHelper

where you would find this solution:

For a simple DatabaseHandler:



    public class MyDatabase extends SQLiteOpenHelper {
      private static final String DATABASE_NAME = "database.db";
      private static final int DATABASE_VERSION = 1;

      public MyDatabase(Context context){
          super(context, DATABASE_NAME, null, DATABASE_VERSION);
      }

      @Override
      public void onCreate(SQLiteDatabase db){
          // some code
      }

      @Override
      public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
          // some code
      }
    }

I created an AndroidTestCase:



  public class DatabaseTest extends AndroidTestCase {
      private MyDatabase db;

        @Override
      public void setUp() throws Exception {
            super.setUp();
          RenamingDelegatingContext context = new RenamingDelegatingContext(getContext(), "test_");
          db = new MyDatabase(context);
      }

        @Override
      public void tearDown() throws Exception {
          db.close(); 
          super.tearDown();
      }

        //According to Zainodis annotation only for legacy and not valid with gradle>1.1:
        //@Test
      public void testAddEntry(){
          // Here i have my new database wich is not connected to the standard database of the App
      }
  }
