_ [Java][Seasar] Cubby入門中

CubbyのRESTっぽいURIが個人的に激しく良いです。でも、Actionの単体テストがどうしたら良いかよくわからないです。org.seasar.cubby.examples.todo.action.LoginActionに対して次のようなテストを書くと。

public class LoginActionTest extends S2TigerTestCase {
    private LoginAction loginAction;

    protected void setUp() throws Exception {
        include("app.dicon");
    }

    public void testLogin() {
        loginAction.sessionScope = new HashMap<String, Object>();
        loginAction.userId = "test";
        loginAction.password = "test";
        loginAction.process();
        assertEquals(1, loginAction.sessionScope.size());
    }
}

次のぬるぽが出ちゃってテスト出来ません。

とりあえずValidationだけをテストするか、Helper MethodもしくはServiceとして実装してそっちでテストかな？。SAStrutsだと返り値がパスを表したStringなので単体テストしやすいです。

と、RESTっぽいURIを持つCubbyとSAStruts の良いとこどりがあれば良いのかも？
