MvvmCross：如何使用從MvxIoCSupportingTest派生的多個測試類

Question

我有兩個從MvxIoCSupportingTest派生的xUnit測試類。 運行單元測試，我收到錯誤消息：

Cirrious.CrossCore.Exceptions.MvxException : You should only initialize MvxBindingSingletonCache once

有沒有辦法顯式地將IoC虛假化為符號？

Answer 1

使用此類而不是MvxIoCSupportingTest

using MvvmCross.Core;
using MvvmCross.Core.Platform;
using MvvmCross.Platform.IoC;
using MvvmCross.Platform.Platform;

namespace MvvmCross.Test.Core
{
    public class BaseMvvmCrossTest
    {
        static BaseMvvmCrossTest()
        {
            if (MvxSimpleIoCContainer.Instance == null)
            {
                MvxSingletonCache.Initialize();
                MvxSimpleIoCContainer.Initialize();

                MvxSimpleIoCContainer.Instance.RegisterSingleton(MvxSimpleIoCContainer.Instance);
                MvxSimpleIoCContainer.Instance.RegisterSingleton<IMvxTrace>(new TestTrace());
                MvxSimpleIoCContainer.Instance.RegisterSingleton<IMvxSettings>(new MvxSettings());

                MvxTrace.Initialize();
            }
        }
    }
}
