Nsubsitute - 在查询处理程序中调用的模拟数据库上下文

Question

有没有办法在这种情况下模拟dbcontext？我正在使用cqrs。

  public class QueryHandler1 : IQueryHandler<Query1,string>
  {
    private readonly IDbInvoker invoker;

    public QueryHandler1 (IDbInvoker invoker)
    {
        this.invoker = invoker;
    }

    public string Handle(Query1 query)
    {
        //Here I want to have my mocked context somehow.
        return invoker.Invoke<MyMockedContext, string>(context =>
        {

            //logic which I want to test with my mocked context
        });
    }
