在单元测试中设置ApiController的User属性

本文关键字：User 属性 ApiController 设置 单元测试 | 更新日期: 2023-09-27 18:03:50

我对ApiController的单元测试使用了一些辅助方法来实例化控制器:

public static ResourcesController SetupResourcesController(HttpRequestMessage request, IResourceMetadataRepository repo, IUnitOfWorkService unitOfWorkService)
{
    var config = new HttpConfiguration();
    var defaultRoute = config.Routes.MapHttpRoute(RouteNames.DefaultApi , "api/{controller}/{id}");
    var routeData = new HttpRouteData(defaultRoute, new HttpRouteValueDictionary { { "controller", "resources" } });
    var resourcesController = new ResourcesController(repo, unitOfWorkService)
    {
        ControllerContext = new HttpControllerContext(config, routeData, request),
        Request = request
    };
    resourcesController.Request.Properties.Add(HttpPropertyKeys.HttpRouteDataKey, routeData);
    resourcesController.Request.Properties[HttpPropertyKeys.HttpConfigurationKey] = config;
    // Compilation fail: The Property 'System.Web.Http.ApiController.User' has no setter.
    resourcesController.User = myStubUserPrincipal;
    return resourcesController;
}

我的问题是:如何设置控制器的User属性?

我试过:

request.Properties.Add("MS_UserPrincipal", myStubUserPrincipal);

但这也不起作用(resourcesController。

在单元测试中设置ApiController的User属性

设置Thread.CurrentPrincipal，将自动初始化控制器中的User属性。

对于看到这个答案，但不知道如何设置CurrentPrincipal的人:这段代码是从MSDN中提取的。

Thread.CurrentPrincipal = new GenericPrincipal
(
   new GenericIdentity("Bob", "Passport"),
   new[] {"managers", "executives"}
);

更简洁的方法是模拟IPrincipal和HttpRequestContext，例如使用Moq:

var userMock = new Mock<IPrincipal>();
userMock.Setup(p => p.IsInRole("admin")).Returns(true);
userMock.SetupGet(p => p.Identity.Name).Returns("tester");
userMock.SetupGet(p => p.Identity.IsAuthenticated).Returns(true);
var requestContext = new Mock<HttpRequestContext>();
requestContext.Setup(x => x.Principal).Returns(userMock.Object);
var controller = new ControllerToTest()
{
    RequestContext = requestContext.Object,
    Request = new HttpRequestMessage(),
    Configuration = new HttpConfiguration()
};
