为 .NET 5 Core Controller 单元测试模拟或实际创建 ODataQueryOptions答案

【问题标题】：Mocking or creating pragmatically ODataQueryOptions for .NET 5 Core Controller unit test为 .NET 5 Core Controller 单元测试模拟或实际创建 ODataQueryOptions

【问题描述】：

我正在将我们现有的 API 迁移到 .net 5，我面临着单元测试迁移的问题。我想保留测试和测试控制器，但我找不到处理 ODataQueryOptions 的方法，因为此类已更改，我再也找不到创建 ODataQueryOptions 的方法。所有与我的问题相关的主题都已过时。

这是在迁移之前如何测试控制器的旧代码

_userController.Request = new HttpRequestMessage(HttpMethod.Get, new Uri("http://localhost/api?$orderby=UserName desc"));
            _queryOptionsUser = new ODataQueryOptions<User>(_queryOptionsUser.Context, _userController.Request);
            PageResult<UserDto> users = _userController.GetUsers(Constants.ValidOrgCode1, _queryOptionsUser);

如果有人能提供狙击手如何处理类似问题并能够测试控制器，我将不胜感激。

最后，我结束了。

有控制器的方法进行单元测试

public PageResult<User> GetAll(ODataQueryOptions<User> odataQuery)

单元测试

// Arrange
var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.EntitySet<User>("User");
var edmModel = modelBuilder.GetEdmModel();

const string routeName = "odata";
IEdmEntitySet entitySet = edmModel.EntityContainer.FindEntitySet("User");
ODataPath path = new ODataPath(new EntitySetSegment(entitySet));

var request = RequestFactory.Create("GET",
    "http://localhost/api?$top=10&",
    dataOptions => dataOptions.AddModel(routeName, edmModel));

request.ODataFeature().Model = edmModel;
request.ODataFeature().Path = path;
request.ODataFeature().PrefixName = routeName;

var oDataQueryContext = new ODataQueryContext(edmModel, typeof(User), new ODataPath());
var aDataQueryOptions = new ODataQueryOptions<User>(oDataQueryContext, request);

// Act
PageResult<User> users = _userController.GetAll(aDataQueryOptions);

您将需要帮助类来生成 HttpRequest

public static class RequestFactory
    {
        /// <summary>
        /// Creates the <see cref="HttpRequest"/> with OData configuration.
        /// </summary>
        /// <param name="method">The http method.</param>
        /// <param name="uri">The http request uri.</param>
        /// <param name="setupAction"></param>
        /// <returns>The HttpRequest.</returns>
        public static HttpRequest Create(string method, string uri, Action<ODataOptions> setupAction)
        {
            HttpContext context = new DefaultHttpContext();
            HttpRequest request = context.Request;

            IServiceCollection services = new ServiceCollection();
            services.Configure(setupAction);
            context.RequestServices = services.BuildServiceProvider();

            request.Method = method;
            var requestUri = new Uri(uri);
            request.Scheme = requestUri.Scheme;
            request.Host = requestUri.IsDefaultPort ? new HostString(requestUri.Host) : new HostString(requestUri.Host, requestUri.Port);
            request.QueryString = new QueryString(requestUri.Query);
            request.Path = new PathString(requestUri.AbsolutePath);
            
            return request;
        }
