我的单元测试一类通过获取注入Autofac一些参数。
一些参数是Func<Delegate> 。 这使我能够创建多个代表使用。 请参阅此Autofac Wiki页面 ，如果你需要一个更好的描述。
下面是类的一部分。
public class CreateProductCommand : TransactionalDBCommandBase<ProductImpl>
{
public delegate CreateProductCommand Factory(ProductInfo info, IAppSecurityContext context);
private ProductInfo _info;
private Func<SaveTextMasterCommand.Factory> _saveTextMasterCommandFactory;
private Func<SaveTextValueCommand.Factory> _saveTextValueCommandFactory;
private SaveProductCommand.Factory _saveProductCommand;
public CreateProductCommand(ProductInfo info, Func<SaveTextMasterCommand.Factory> saveTextMasterCommandFactory,
Func<SaveTextValueCommand.Factory> saveTextValueCommandFactory, SaveProductCommand.Factory saveProductCommand, IAppSecurityContext context)
{
this._info = info;
this._saveTextMasterCommandFactory = saveTextMasterCommandFactory;
this._saveTextValueCommandFactory = saveTextValueCommandFactory;
this._saveProductCommand = saveProductCommand;
this.CurrentContext = context;
}
public override ProductImpl Execute(IDataTransaction dataTrans)
{
//More code here
this._saveTextMasterCommandFactory().Invoke(SomeParam,SomeParam2).Execute(dataTrans);
//Some time later
this._saveTextMasterCommandFactory().Invoke(SomeDiffParam,SomeDiffParam2).Execute(dataTrans);
}
}
测试类看起来是这样的。 安装程序是巨大的。 我对齐代码块中的问题是左侧。

saveProductDelMock.Expect(m => m(Arg<ProductImpl>.Is.Equal(product), Arg<IAppSecurityContext>.Is.Anything)).Return(saveProductCommandMock);
}
}
例外情况是：无法投类型“ProxyDelegate_Factory_3Proxyef78e79dacee4c759351a5ffaa933f85”的目的为类型“工厂”。
我不完全知道如何修复此问题。
