これが私のアクションメソッドであると仮定しましょう
public IHttpActionResult Get(int id)
{
var status = GetSomething(id);
if (status)
{
return Ok();
}
else
{
return NotFound();
}
}
テストは
var httpActionResult = controller.Get(1);
この後、httpステータスコードを確認するにはどうすればよいですか?
ここでOk()
は、応答ステータスをHttpStatusCode.Ok
...に設定するOkResult
型の単なるヘルパーです。したがって、アクション結果のインスタンスがOkResult
...いくつかの例(XUnit
で記述):
// if your action returns: NotFound()
IHttpActionResult actionResult = valuesController.Get(10);
Assert.IsType<NotFoundResult>(actionResult);
// if your action returns: Ok()
actionResult = valuesController.Get(11);
Assert.IsType<OkResult>(actionResult);
// if your action was returning data in the body like: Ok<string>("data: 12")
actionResult = valuesController.Get(12);
OkNegotiatedContentResult<string> conNegResult = Assert.IsType<OkNegotiatedContentResult<string>>(actionResult);
Assert.Equal("data: 12", conNegResult.Content);
// if your action was returning data in the body like: Content<string>(HttpStatusCode.Accepted, "some updated data");
actionResult = valuesController.Get(13);
NegotiatedContentResult<string> negResult = Assert.IsType<NegotiatedContentResult<string>>(actionResult);
Assert.Equal(HttpStatusCode.Accepted, negResult.StatusCode);
Assert.Equal("some updated data", negResult.Content);
死んだ質問を復活させる時
現在の回答はすべて、応答オブジェクトを既知のタイプにキャストすることに依存しています。残念ながら、応答には、コントローラーの実装に関する詳細な知識がなくても、これが機能するための使用可能な階層または暗黙的な変換パスがないようです。以下を考慮してください。
public class MixedCodeStandardController : ApiController {
public readonly object _data = new Object();
public IHttpActionResult Get() {
return Ok(_data);
}
public IHttpActionResult Get(int id) {
return Content(HttpStatusCode.Success, _data);
}
}
クラスのテスト:
var testController = new MixedCodeStandardController();
var getResult = testController.Get();
var posRes = getResult as OkNegotiatedContentResult<object>;
Assert.IsType<OkNegotiatedContentResult<object>>(getResult);
Assert.AreEqual(HttpStatusCode.Success, posRes.StatusCode);
Assert.AreEqual(testController._data, posRes.Content);
var idResult = testController.Get(1);
var oddRes = getResult as OkNegotiatedContentResult<object>; // oddRes is null
Assert.IsType<OkNegotiatedContentResult<object>>(idResult); // throws failed assertion
Assert.AreEqual(HttpStatusCode.Success, oddRes.StatusCode); // throws for null ref
Assert.AreEqual(testController._data, oddRes.Content); // throws for null ref
ブラックボックスの外側からの応答ストリームは基本的に同じです。この方法でテストするには、テストでコントローラーがどのようにリターンコールを実装したかを知る必要があります。
代わりに、返されたIHttpActionResultのHttpResponseMessageオブジェクトを使用します。これにより、コントローラーコードが次のようにならない場合でも、テストの一貫性を確保できます。
var testController = new MixedCodeStandardController();
var getResult = testController.Get();
var getResponse = getResult.ExecuteAsync(CancellationToken.None).Result;
Assert.IsTrue(getResponse.IsSuccessStatusCode);
Assert.AreEqual(HttpStatusCode.Success, getResponse.StatusCode);
var idResult = testController.Get(1);
var idResponse = idResult.ExecuteAsync(CancellationToken.None).Result;
Assert.IsTrue(idResponse.IsSuccessStatusCode);
Assert.AreEqual(HttpStatusCode.Success, idResponse.StatusCode);
これは、キランチャラによって受け入れられた回答であり、NUnitに適合しています。
var valuesController = controller;
// if your action returns: NotFound()
IHttpActionResult actionResult = valuesController.Get(10);
var notFoundRes = actionResult as NotFoundResult;
Assert.IsNotNull(notFoundRes);
// if your action returns: Ok()
actionResult = valuesController.Get(11);
var posRes = actionResult as OkResult;
Assert.IsNotNull(posRes);
// if your action was returning data in the body like: Ok<string>("data: 12")
actionResult = valuesController.Get(12);
var conNegResult = actionResult as OkNegotiatedContentResult<string>;
Assert.IsNotNull(conNegResult);
Assert.AreEqual("data: 12", conNegResult.Content);
// if your action was returning data in the body like: Content<string>(HttpStatusCode.Accepted, "some updated data");
actionResult = valuesController.Get(13);
var negResult = actionResult as NegotiatedContentResult<string>;
Assert.IsNotNull(negResult);
Assert.AreEqual(HttpStatusCode.Accepted, negResult.StatusCode);
Assert.AreEqual("some updated data", negResult.Content);
Assert.IsInstanceOfType(httpActionResult、typeof(OkResult));
IHttpActionResultにJSONオブジェクトが含まれている場合、たとえば{"token": "A"}、次のコードを使用できます。
var result = usercontroller.GetLogin("user", "password");
Assert.IsInstanceOfType(result, typeof(OkNegotiatedContentResult<Dictionary<string,string>>));
var content = result as OkNegotiatedContentResult<Dictionary<string, string> >;
Assert.AreEqual("A", content.Content["token"]);
数時間の調査と試行の後、最終的にIHttpActionResult
を返すWeb API 2メソッドを完全にテストし、OWINミドルウェアとASP.NET Identityのデフォルト実装を使用する方法を見つけました。
次のApiController
でGet()
メソッドをテストします。
public class AccountController : ApiController
{
private ApplicationUserManager _userManager;
public ApplicationUserManager UserManager => _userManager ?? HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
[Route("api/account"), HttpGet]
public async Task<IHttpActionResult> Get()
{
var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
if (user == null)
{
ModelState.AddModelError(ModelStateConstants.Errors, "Account not found! Try logging out and in again.");
return BadRequest(ModelState);
}
var roles = await UserManager.GetRolesAsync(user.Id);
var accountModel = new AccountViewModel
{
FullName = user.FullName,
Email = user.Email,
Phone = user.PhoneNumber,
Organization = user.Organization.Name,
Role = string.Join(", ", roles)
};
return Ok(accountModel);
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
if (_userManager != null)
{
_userManager.Dispose();
_userManager = null;
}
}
base.Dispose(disposing);
}
}
すべてのテストクラスが継承する基本クラスから始めます。
public class BaseTest
{
protected static User CurrentUser;
protected static IList<string> Roles;
public BaseTest()
{
var email = "[email protected]";
CurrentUser = new User
{
FullName = "Unit Tester",
Email = email,
UserName = email,
PhoneNumber = "123456",
Organization = new Organization
{
Name = "Test Organization"
}
};
Roles = new List<string>
{
"Administrator"
};
}
protected void InitializeApiController(ApiController apiController)
{
//Init fake controller Http and Identity data
var config = new HttpConfiguration();
var request = new HttpRequestMessage();
var routeData = new HttpRouteData(new HttpRoute(""));
apiController.ControllerContext = new HttpControllerContext(config, routeData, request)
{
Configuration = config
};
apiController.User = new GenericPrincipal(new GenericIdentity(""), new[] { "" });
//Initialize Mocks
var appUserMgrMock = GetMockedApplicationUserManager();
var appSignInMgr = GetMockedApplicationSignInManager(appUserMgrMock);
var appDbContext = GetMockedApplicationDbContext();
//Configure HttpContext.Current.GetOwinContext to return mocks
var owin = new OwinContext();
owin.Set(appUserMgrMock.Object);
owin.Set(appSignInMgr.Object);
owin.Set(appDbContext.Object);
HttpContext.Current = new HttpContext(new HttpRequest(null, "http://test.com", null), new HttpResponse(null));
HttpContext.Current.Items["owin.Environment"] = owin.Environment;
}
private static Mock<ApplicationSignInManager> GetMockedApplicationSignInManager(Mock<ApplicationUserManager> appUserMgrMock)
{
var authMgr = new Mock<Microsoft.Owin.Security.IAuthenticationManager>();
var appSignInMgr = new Mock<ApplicationSignInManager>(appUserMgrMock.Object, authMgr.Object);
return appSignInMgr;
}
private Mock<ApplicationUserManager> GetMockedApplicationUserManager()
{
var userStore = new Mock<IUserStore<User>>();
var appUserMgr = new Mock<ApplicationUserManager>(userStore.Object);
appUserMgr.Setup(aum => aum.FindByIdAsync(It.IsAny<string>())).ReturnsAsync(CurrentUser);
appUserMgr.Setup(aum => aum.GetRolesAsync(It.IsAny<string>())).ReturnsAsync(Roles);
return appUserMgr;
}
private static Mock<ApplicationDbContext> GetMockedApplicationDbContext()
{
var dbContext = new Mock<ApplicationDbContext>();
dbContext.Setup(dbc => dbc.Users).Returns(MockedUsersDbSet);
return dbContext;
}
private static IDbSet<User> MockedUsersDbSet()
{
var users = new List<User>
{
CurrentUser,
new User
{
FullName = "Testguy #1",
Email = "[email protected]",
UserName = "[email protected]",
PhoneNumber = "123456",
Organization = new Organization
{
Name = "Test Organization"
}
}
}.AsQueryable();
var usersMock = new Mock<DbSet<User>>();
usersMock.As<IQueryable<User>>().Setup(m => m.Provider).Returns(users.Provider);
usersMock.As<IQueryable<User>>().Setup(m => m.Expression).Returns(users.Expression);
usersMock.As<IQueryable<User>>().Setup(m => m.ElementType).Returns(users.ElementType);
usersMock.As<IQueryable<User>>().Setup(m => m.GetEnumerator()).Returns(users.GetEnumerator);
return usersMock.Object;
}
}
InitializeApiController
メソッドには、肉とジャガイモが含まれています。
これで、AccountController
のテストを作成できます。
public class AccountControllerTests : BaseTest
{
private readonly AccountController _accountController;
public AccountControllerTests()
{
_accountController = new AccountController();
InitializeApiController(_accountController);
}
[Test]
public async Task GetShouldReturnOk()
{
var result = await _accountController.Get();
var response = await result.ExecuteAsync(CancellationToken.None);
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
}
}
すべてが機能するには、Microsoft.OWIN.*
およびMicrosoft.AspNet.*
パッケージの束をインストールする必要があります。ここにpackages.config
を貼り付けます。
