Batch process which periodically archive SObjects to Big Objects


It may have been solved.

I could not use the Apex stub API to mock big object insert (given that I would have to stub the calls in the Database namespace, which is not possible). The only solution avaliable to me is to isolate the database insert/delete operations in a separate interface. Have an implementation for production and a mock implementation for tests that persists the object in-memory instead. Very cumbersome and annoying.

Apex スタブ API を使用して大きなオブジェクトの挿入をモックすることはできませんでした (データベース名前空間でコールをスタブ化する必要があるため、これは不可能です)。
私が利用できる唯一の解決策は、データベースの挿入/削除操作を別のインターフェイスに分離することです。
実稼働用の実装と、代わりにオブジェクトをメモリ内に保持するテスト用のモック実装を用意してください。非常に面倒で迷惑です。
