Moq C#MongoDB FindAsync返回值

最近，我们为Mongo实现了一个通用版本的存储库

存储库

public async Task<IList<T>> FindAsync<T>(FilterDefinition<T> t) where T : IMongoModel
{
    var collection = _connection.GetCollection<T>();
    var result = await collection.FindAsync<T>(t);
    return await result.ToListAsync();
}

public async Task<IList<T>> FindAsync<T>(Expression<Func<T, bool>> filter) where T : IMongoModel
{
    var collection = _connection.GetCollection<T>();
    var result = await collection.FindAsync(filter);
    return await result.ToListAsync();
}

公共异步任务FindAsync（FilterDefinition t），其中t:IMongoModel
{
var collection=_connection.GetCollection（）；
var result=await collection.FindAsync（t）；
返回等待结果。toListSync（）；
}
公共异步任务FindAsync（表达式筛选器），其中T:IMongoModel
{
var collection=_connection.GetCollection（）；
var result=await collection.FindAsync（过滤器）；
返回等待结果。toListSync（）；
}

正在调用的代码

private async Task<MongoDb.Advertisement.Service.Models.AdvertisementFiles.Advertisement> DealerZipCodeAndLocation(MongoDb.Advertisement.Service.Models.AdvertisementFiles.Advertisement advertisement, string searchPhone)
{
    var matchingDealers = await _mongoRepository.FindAsync(Builders<Dealer>.Filter.ElemMatch(y => y.Phones, z => z.PhoneNumber == searchPhone));
    if (!matchingDealers.Any())
    {
        return advertisement;
    }
    if (matchingDealers.Count > 1)
    {
        _logger.Warning("More than one dealer found with {PhoneNumber}", searchPhone);
    }
    var matchingDealer = matchingDealers.FirstOrDefault();
    if (matchingDealer.Geocode == null)
    {
        var geoCode = await _geoLocationCache.GetGeocodByZipCode(matchingDealer.Address.ZipCode);

        if (geoCode.status != "OK")
        {
            return advertisement;
        }
        advertisement.Geocode = geoCode;
        advertisement.ZipCode = matchingDealer.Address.ZipCode;
        await UpdateGeocode<Dealer>(matchingDealer.Id, geoCode);
    }

    return advertisement;
}

public IList<Dealer> GetDealerWithZipCode()
{
    return new List<Dealer>
    {
        new Dealer
        {
            Active = true,
            DealerName = "City Chevrolet",
            Phones = new List<Phone>
            {
                new Phone
                {
                    PhoneNumber = "4033809999"
                }
            },
            MasterCode = "CHEV01",
            RevisionDate = DateTime.UtcNow
        }
    };
}

public async Task<IList<Dealer>> GetDealerWithZipCode()
{
    return await Task.Run(() => new List<Dealer>
    {
        new Dealer
        {
            Active = true,
            DealerName = "City Chevrolet",
            Phones = new List<Phone>
            {
                new Phone
                {
                    PhoneNumber = "4033809999"
                }
            },
            MasterCode = "CHEV01",
            RevisionDate = DateTime.UtcNow
        }
    });
}

private async Task DealerZipCodeAndLocation（MongoDb.advision.Service.Models.advisementfiles.advision advision，string searchPhone）
{
var matchingderals=wait _mongoRepository.FindAsync（Builders.Filter.ElemMatch（y=>y.Phones，z=>z.PhoneNumber==searchPhone））；
如果（！matchingDealers.Any（））
{
退货广告；
}
如果（匹配经销商数>1）
{
_logger.Warning（“找到多个具有{PhoneNumber}的经销商”，searchPhone）；
}
var matchingDealer=matchingDealers.FirstOrDefault（）；
if（matchingDealer.Geocode==null）
{
var geoCode=await_geoLocationCache.GetGeocodByZipCode（matchingDealer.Address.ZipCode）；
如果（geoCode.status！=“正常”）
{
退货广告；
}
广告。地理编码=地理编码；
advision.ZipCode=matchingDealer.Address.ZipCode；
等待更新代码（matchingDealer.Id，地理代码）；
}
退货广告；
}

还尝试了以下签名

var matchingDealers = await _mongoRepository.FindAsync<Dealer>(x => x.Phones.Any(y => y.PhoneNumber == searchPhone));
var matchingDealers = await _mongoRepository.FindAsync(filter);

var matchingderals=wait _mongoRepository.FindAsync（x=>x.Phones.Any（y=>y.PhoneNumber==searchPhone））；
var matchingDealers=Wait _mongoRepository.FindAsync（过滤器）；

当模拟FindAsync调用时，我在返回时遇到了困难。问题要么是签名不匹配，要么更可能是异步

最小起订量设置 我已经尝试了这两个版本（也用

It.IsAny（）

代替电话号码）

\u testFixture.MongoRepository.Setup（x=>x.FindAsync（Builders.Filter.ElemMatch（y=>y.Phones，z=>z.PhoneNumber==\u testFixture.GetAdvertisementWithNoZipCode（）.OriginalPhoneNumber））。返回（Task.FromResult（\u testFixture.getDealWithzipcode（））；
_testFixture.MongoRepository.Setup（x=>x.FindAsync（Builders.Filter.ElemMatch（y=>y.Phones，z=>z.PhoneNumber==_testFixture.GetAdvertisementWithNoZipCode（）.OriginalPhoneNumber））.ReturnsAsync（_testFixture.getDealWithzipcode（））；

返回已尝试的对象

{
    var matchingDealers = await _mongoRepository.FindAsync(Builders<Dealer>.Filter.ElemMatch(y => y.Phones, z => z.PhoneNumber == searchPhone));
    if (!matchingDealers.Any())
    {
        return advertisement;
    }
    if (matchingDealers.Count > 1)
    {
        _logger.Warning("More than one dealer found with {PhoneNumber}", searchPhone);
    }
    var matchingDealer = matchingDealers.FirstOrDefault();
    if (matchingDealer.Geocode == null)
    {
        var geoCode = await _geoLocationCache.GetGeocodByZipCode(matchingDealer.Address.ZipCode);

        if (geoCode.status != "OK")
        {
            return advertisement;
        }
        advertisement.Geocode = geoCode;
        advertisement.ZipCode = matchingDealer.Address.ZipCode;
        await UpdateGeocode<Dealer>(matchingDealer.Id, geoCode);
    }

    return advertisement;
