Zenject Unity3D测试场景点击“无法解析类”如何摆脱?

我有SceneA(A)和SceneB(B)。B还有一个fooassingle和NonLazy,由SceneContext安装程序安装。Foo实现了一个IInitialize删除日志(“你好错误!”):

yield return LoadScene("SceneA");
yield return new WaitForSeconds(2.0f);
SceneManager.LoadScene("SceneB");
yield return new WaitForSeconds(2.0f);
var newSceneContainer = ProjectContext.Instance.Container.Resolve<SceneContextRegistry>()
.SceneContexts.Single().Container;
Foo foo = newSceneContainer.Resolve<Foo>();

**--编辑--1**

A的安装程序为空。 B代码:

public class BInstaller : MonoInstaller
{
    public override void InstallBindings()
    {
        Container.BindInterfacesAndSelfTo<BClass>().AsSingle().NonLazy();
    }
}

public class BClass : IInitializable, IDisposable {
    public void Initialize() { Debug.Log("Hello Errors!"); }
    public void Dispose() { }
}

public class ScenesFlow_A_to_B : SceneTestFixture
{
    [UnityTest]
    public IEnumerator TestScene()
    {
        yield return LoadScene("SceneA");
        //waiting
        SceneManager.LoadScene("SceneB");
        //waiting
        var newSceneContainer = ProjectContext.Instance.Container
        .Resolve<SceneContextRegistry>().SceneContexts.Single().Container;
        BClass bc = newSceneContainer.Resolve<BClass>() as BClass;
        Assert.IsNotNull(bc);// fail!
    }
}

新变化:

public class ScenesFlow_A_to_B : SceneTestFixture
{
    [UnityTest]
    public IEnumerator TestScene()
    {
        yield return LoadScene("SceneA");
        //SceneManager.LoadScene("SceneB");
        yield return SceneManager.LoadSceneAsync("SceneB");
        var newSceneContainer = ProjectContext.Instance.Container
        .Resolve<SceneContextRegistry>().SceneContexts.Single().Container;
        BClass bc = newSceneContainer.Resolve<BClass>() as BClass;
        Assert.IsNotNull(bc);
    }
}

结果是:
