我試圖寫我的一個小項目的一些測試,但他們忽視了(我從1個開始測試「Create_Class」)在ASP.NET MVC3(用DI)TDD問題
我用的是庫模式,並使用構造函數依賴注入:
public KlasController() {
db = ObjectContextPerHttpRequest.Context;
KlasRepo = new KlasRepository(db);
LesRepo = new LesRepository(db);
OpdrachtRepo = new OpdrachtRepository(db);
}
//dependency injection constructor
public KlasController(IKlasRepository KlasRepo, ILesRepository LesRepo,
IOpdrachtRepository OpdrachtRepo) {
this.KlasRepo = KlasRepo;
this.LesRepo = LesRepo;
this.OpdrachtRepo = OpdrachtRepo;
}
,這裏是我的TestClass與testinitializer(其中每個測試之前運行)和第一測試
[TestClass()]
public class KlasControllerTest
{
private KlasController Controller;
private IOpdrachtRepository OpdrachtRepo;
//Use TestInitialize to run code before running each test
[TestInitialize()]
public void MyTestInitialize()
{
OpdrachtRepo = new DummyOpdrachtRepository();
Controller = new KlasController(new DummyKlasRepository(),
new DummyLesRepository(), OpdrachtRepo);
Opdracht TestOpdracht = new Opdracht
{
OpdrachtID = 1,
VakID = 1,
StamNummer = "im1"
};
Vak TestVak = new Vak { VakID = 1, VakNaam = "FOOP" };
TestOpdracht.Vak = TestVak;
OpdrachtRepo.addOpdracht(TestOpdracht);
}
/// <summary>
///A test for Index
///</summary>
[TestMethod()]
public void CreateKlasDirectsToToonKlassen()
{
Klas Klas = new Klas { KlasNaam = "2dNet" };
RedirectToRouteResult view = Controller.Create(1) as RedirectToRouteResult;
Assert.IsNotNull(view);
Assert.AreEqual("ToonKlassen", view.RouteValues["action"]);
}
}
此刻我得到一個nullreferenc在視圖eException(assert.isNotNull失敗)
,這裏是我的DummyRepository的一個:
class DummyOpdrachtRepository : IOpdrachtRepository
{
List<Opdracht> opdrachten;
public DummyOpdrachtRepository()
{
opdrachten = new List<Opdracht>();
}
public void addOpdracht(Opdracht opdracht)
{
opdrachten.Add(opdracht);
}
public string GetDocentID(int OpdrachtID)
{
var opdracht = opdrachten.Where(o => o.OpdrachtID == OpdrachtID).FirstOrDefault();
return opdracht.StamNummer;
}
public Opdracht Find(int id)
{
return opdrachten.Where(o => o.OpdrachtID == id).FirstOrDefault();
}
}
通常,我應該寫書面方式代碼之前,我所知道的測試(和我深信關閉TDD ,因爲我在我最新的Java項目中成功地使用了它)。但它只是似乎沒有工作..
這裏是KlasController.Create行動
public ActionResult Create(int id) //id = opdrachtID
{
var Opdracht = OpdrachtRepo.Find(id);
Vak vak;
if(Opdracht != null)
vak = Opdracht.Vak;
else
throw new NullReferenceException("Deze opdracht werd niet gevonden");
return View(new CreateKlasModel(id,vak));
}
的代碼,我知道這是一個很大的代碼,但我真的想使這項工作。
謝謝你幫我提前出局:)
根據您的測試方法創建操作必須返回RedirectToRouteResult類型的結果。這樣對嗎? – vladimir77
