测试 WebApi 控制器时如何生成 Asp.net 用户身份

我正在使用 Web API 2。在 web api 控制器中我使用过GetUserId使用 Asp.net Identity 生成用户 ID 的方法。

我必须为该控制器编写 MS 单元测试。如何从测试项目访问用户 ID？

我在下面附上了示例代码。

网络 API 控制器

public IHttpActionResult SavePlayerLoc(IEnumerable<int> playerLocations)
{
    int userId = RequestContext.Principal.Identity.GetUserId<int>();
    bool isSavePlayerLocSaved = sample.SavePlayerLoc(userId, playerLocations);
    return Ok(isSavePlayerLocSaved );
}

Web API 控制器测试类

[TestMethod()]
public void SavePlayerLocTests()
{
    var context = new Mock<HttpContextBase>();
    var mockIdentity = new Mock<IIdentity>();
    context.SetupGet(x => x.User.Identity).Returns(mockIdentity.Object);
    mockIdentity.Setup(x => x.Name).Returns("admin");
    var controller = new TestApiController();
    var actionResult = controller.SavePlayerLoc(GetLocationList());
    var response = actionResult as OkNegotiatedContentResult<IEnumerable<bool>>;
    Assert.IsNotNull(response);
}

我尝试使用上面的模拟方法。但它不起作用。当我从测试方法调用控制器时，如何生成 Asp.net 用户身份？

如果请求经过身份验证，则应使用相同的原则填充 User 属性

public IHttpActionResult SavePlayerLoc(IEnumerable<int> playerLocations) {
    int userId = User.Identity.GetUserId<int>();
    bool isSavePlayerLocSaved = sample.SavePlayerLoc(userId, playerLocations);
    return Ok(isSavePlayerLocSaved );
}

for ApiController你可以设置User安排单元测试时的属性。然而，该扩展方法正在寻找一个ClaimsIdentity所以你应该提供一个

测试现在看起来像

[TestMethod()]
public void SavePlayerLocTests() {
    //Arrange
    //Create test user
    var username = "admin";
    var userId = 2;

    var identity = new GenericIdentity(username, "");
    identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, userId.ToString()));
    identity.AddClaim(new Claim(ClaimTypes.Name, username));

    var principal = new GenericPrincipal(identity, roles: new string[] { });
    var user = new ClaimsPrincipal(principal);

    // Set the User on the controller directly
    var controller = new TestApiController() {
        User = user
    };

    //Act
    var actionResult = controller.SavePlayerLoc(GetLocationList());
    var response = actionResult as OkNegotiatedContentResult<IEnumerable<bool>>;

    //Assert
    Assert.IsNotNull(response);
}
