模拟表达参数到存储库方法

使用起订量。我有一个具有以下接口的存储库：

public virtual IEnumerable<TEntity> GetBySpec(ISpecification<TEntity> specification, params string[] includes)
{
        IQueryable<TEntity> query = includes.Aggregate<string, IQueryable<TEntity>>(_dbSetQuery, (current, include) => current.Include(include));

        return query.Where(specification.SatisfiedBy())
                                 .AsEnumerable<TEntity>();
}

在这种情况下，我使用的是DirectSpecification：

public sealed class DirectSpecification<TEntity> : Specification<TEntity>
{
    Expression<Func<TEntity, bool>> _MatchingCriteria;

    public DirectSpecification(Expression<Func<TEntity, bool>> matchingCriteria)
    {
        _MatchingCriteria = matchingCriteria;
    }

    public override Expression<Func<TEntity, bool>> SatisfiedBy()
    {
        return _MatchingCriteria;
    }
}

用我的实际代码打电话

var recentlyChanged = _vwPersonRepository.GetBySpec(
               new DirectSpecification<vwPerson>(person =>
                   person.ModifiedDate > modifiedFromDay &&
                   person.ModifiedDate < modifiedTo));

var recentlyCreated = _vwPersonRepository.GetBySpec(
               new DirectSpecification<vwPerson>(person =>
                   person.CreatedDate > createdFromDay &&
                   person.CreatedDate < createdTo));

编辑：正如重复所建议的，我已经尝试过了：

        Container.GetMock<IvwPersonRepository>()
            .Setup(p => p.GetBySpec(It.IsAny<ISpecification<vwPerson>>()))                        
            .Returns((Expression<Func<vwPerson, bool>> predicate) => 
              items.Where(predicate));

我得到一个

Exception thrown: 'System.Reflection.TargetParameterCountException' in mscorlib.dll

Additional information: Parameter count mismatch.

我的问题因拥有ISpecification参数而变得复杂，如何获得正确的参数以便可以使用谓词？

编辑2：感谢Patrick，这是解决方案：

        Container.GetMock<IvwPersonRepository>()
            .Setup(p => p.GetBySpec(It.IsAny<ISpecification<vwPerson>>(), It.IsAny<string[]>()))                        
            .Returns((ISpecification<vwPerson> specification, string[] includes) => 
              items.Where(predicate));

他们的关键是要包含string[] includes，即使我没有将其作为参数传递，反射也能找到它并希望它在那里。

杰出的！
