Rhino 用 CompositionContainer 模拟异常

本文关键字：异常 模拟 CompositionContainer Rhino | 更新日期: 2023-09-27 18:35:55

[TestFixture]
public class UnitListViewModelTests
{
    private CompositionContainer _container;
    private INHDataService _nhDataService;
    private INHUnitOfWork _nhUoW;
    [SetUp]
    [TestCase]
    public void create_container()
    {
        _container = MockRepository.GeneratePartialMock<CompositionContainer>();
        _nhDataService = MockRepository.GenerateMock<INHDataService>();
        _nhUoW = MockRepository.GenerateMock<INHUnitOfWork>();
        _container.Expect(x => x.GetExportedValue<INHDataService>()).IgnoreArguments().Return(_nhDataService);
    }
}

此代码在 _container.Expect... 处引发异常。

编辑：我也试过这个，但它仍然抛出一个异常：

_container.Stub(x => x.GetExportedValue<INHDataService>()).IgnoreArguments().Return(_nhDataService);

Rhino 用 CompositionContainer 模拟异常

我猜CompositionContainer.GetExportedValue()方法不是虚拟的。
