如何在测试WebApi控制器时生成Asp.net用户身份

Question

我正在使用Web API 2.在web api控制器中,我使用了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.如何从测试项目中访问用户ID？

我在下面附上了示例代码.

Web 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.但它没有用.当我从测试方法调用到控制器时,如何生成Asp.net用户身份？

Answer 1

如果请求已通过身份验证,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 );
}

因为ApiController你可以User在安排单元测试时设置属性.然而,这种扩展方法正在寻找一个,ClaimsIdentity所以你应该提供一个

现在的测试看起来像

[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);
}
