DAOレイヤーをテストする適切な方法は何ですか?
作成および破棄したメソッドに注釈@BeforeMethod
を付けましたが、複数のテストでは機能しませんでした。テストは 1 つずつ実行すると成功しましたが、Maven ビルドではすべて一緒に実行すると成功しなかったため、TestNg グループを使用してテストをグループ化し、Hibernate で同じことを行ったメソッドを実行することにしました。@AfterMethod
SessionFactory
@BeforeGroup
@AfterGroup
だから私はこのようなことをしました:
@Test(groups = {"integration"})
public class IntegrationTest
{
protected SessionFactory sessionFactory;
@BeforeGroups(groups = {"integration"})
public void setUpHibernate() throws Exception
{
// here I configure sessionFactory
this.sessionFactory = ...
}
@AfterGroups(groups = {"integration"})
public void putItDown() throws Exception
{
sessionFactory.close();
}
}
そして、私の各テストはこのクラスを次のように拡張しました
@Test(groups = "integration")
public class RateRepositoryHibernateTest extends IntegrationTest
{
...
}
そして、拡張テストが 1 つしかsessionFactory
設定されておらず、残りはnull
驚くことではありませんでした。今、私は本当に何をすべきかわかりません。
@BeforeGroup
グループテストメソッドのメソッドからデータを渡す方法は?
また
どうやってそれを違う方法で行うのですか?
また
SessionFactory
各テストの前後にsetUpとtearDownを行う方法ですが、複数のテストで悲観的なロック例外が発生しないようにする方法は?

別の方法を説明する回答も大歓迎です。TestNg、Hibernate、およびメモリ内データベースを使用した統合テストの最先端を知りたいです。
