docs: If a {@link ContentProvider} is registered for the given {@link Uri}, its {@link
  ContentProvider#bulkInsert(Uri, ContentValues[])} method will be invoked.
  
  <p>Tests can verify that this method was called using {@link #getStatements()} or {@link
  #getInsertStatements()}.
  
  <p>If no appropriate {@link ContentProvider} is found, no action will be taken and the number
  of rows in {@code values} will be returned.
