我在我的 Blazor 应用程序的一个 razor 组件中使用 Fluxor 进行状态管理，但我不确定如何设置它以使用 Moq 进行测试。我不能仅仅为学生分配一个价值，因为它是一个仅限于初始化的属性。是否有特定的方法来设置 Fluxor 进行测试？

代码

var teacherService = new Mock<ITeacherService>();
            var  localStorage = new Mock<ILocalStorageService>();
            var  studentService = new Mock<IStudentService>();
            var  toastService = new Mock<IToastService>();
            var  NavigationManager = new Mock<NavigationManager>();
            var  Dispatcher = new Mock<IDispatcher>();
            var actionSubscriber = new Mock<IActionSubscriber>();

            var StudentsState = new Mock<IState<StudentsState>>();
            var TeacherState = new Mock<IState<TeacherState>>();

            // Help here
            StudentsState.Setup(t => t.Value.Students = )

我被困了很长一段时间，但浏览了 Fluxor 的闪光社区，发现了一些可能有帮助的东西！我知道您想使用 Moq 进行测试，但也许我发现的可能更容易/适合您测试 Fluxor 组件的目的！

我没有使用起订量，而是遵循这种格式并设法使某些东西起作用：

测试.cs

public class InhousePetOwnerStateTests
{
    private readonly IServiceProvider ServiceProvider;
    private readonly IStore Store;
    private readonly IState<InhousePetOwnerListState> State;
    public InhousePetOwnerStateTests()
    {
        var services = new ServiceCollection();
        services.AddFluxor(x =>
        x
            .ScanAssemblies(GetType().Assembly)
            .ScanTypes(typeof(InhousePetOwnerListState), typeof(Reducers)));
    
        ServiceProvider = services.BuildServiceProvider();
        Store = ServiceProvider.GetRequiredService<IStore>();
        State = ServiceProvider.GetRequiredService<IState<InhousePetOwnerListState>>();
        Store.InitializeAsync().Wait();
    }

    [Fact]
    public void SetInhousePetOwnerList_Empty_StateUpdated()
    {
        Store.Dispatch(new SetInhousePetOwnerListAction(new()));
        Assert.Empty(State.Value.InhousePetOwners);
    }
        
    [Fact]
    public void SetInhousePetOwnerList_MultipleInhouseOwners_StateUpdated()
    {
        List<InhousePetOwner> inhousePetOwners = new List<InhousePetOwner>
        {
            new InhousePetOwner()
            {
                InhousePetOwnerId = 1,
                PetOwnerId = 1,
                TimeIn = System.DateTime.Now
            },
            new InhousePetOwner()
            {
                InhousePetOwnerId = 2,
                PetOwnerId = 2,
                TimeIn = System.DateTime.Now
            },
        };
        Store.Dispatch(new SetInhousePetOwnerListAction(inhousePetOwners));
        Assert.Equal(2, State.Value.InhousePetOwners.Count);
    }
}

在构造函数中，我们创建一个服务集合并添加 Fluxor（就像您在 Startup.cs 中所做的那样），然后扫描程序集。

在上面的代码中，我扫描了 Reducers 和 State。请在此处参考我的目录结构（您将了解我是如何决定包含哪些内容的）。

动作.cs

public class SetInhousePetOwnerListAction
{
    public List<InhousePetOwner> InhousePetOwners { get; }
    public SetInhousePetOwnerListAction(List<InhousePetOwner> inhousePetOwners)
    {
        InhousePetOwners = inhousePetOwners;
    }
}

Reducers.cs（在构造函数中扫描）

public static class Reducers
{
    [ReducerMethod]
    public static InhousePetOwnerListState ReduceSetInhousePetOwnerListAction(InhousePetOwnerListState state, SetInhousePetOwnerListAction action)
    {
        return new InhousePetOwnerListState(inhousePetOwners: action.InhousePetOwners);
    }
}

InhousePetOwnerState.cs（在构造函数中扫描）

public class InhousePetOwnerListState
{
    public List<InhousePetOwner> InhousePetOwners { get; }

    private InhousePetOwnerListState() { }

    public InhousePetOwnerListState(List<InhousePetOwner> inhousePetOwners)
    {
        InhousePetOwners = inhousePetOwners;
    }
}

这个解决方案的作用是它允许您注入所有 Fluxor 状态、动作和减速器，使您能够像往常一样调用它们——我发现这种方式很容易测试！

我这样做的方法是使用设置返回整个状态记录，并按照我想要的方式进行配置。

因此，如果您有一个 StudentState 为只读的 IState

你可以做：

       var studentState = new Mock<IState<StudentsState>>();
            studentState.Setup(s => s.Value)
             .Returns(
                new StudentsState 
                  { 
                      Students = new List<StudentRecord> 
                         { ... }
                   });
