Mongo 模拟集合

  • 772

我试图冻结MongoDB。我在 Internet 上找到了我需要模拟MongoCursor的内容（来自命名空间MongoDB.Driver）——它不存在，或者它不突出。

以下是到目前为止所写的内容：

var collection = new Mock<IMongoCollection<UiCustomizationData>>();

collection.Setup(mongoCollection => temp);


var database = new Mock<IMongoDatabase>();

database.Setup(x =>
  x.GetCollection<UiCustomizationData>("UiCustomizationData", new MongoCollectionSettings()))
   .Returns(collection.Object);

var repo = new UiCustomizationRepository(new UiCustomizationDataContext(database.Object));

我在嘲笑我的基地，我想把我自己的加入收藏。

    从逻辑上讲，您需要模拟IMongoCursor<T>，例如：

    var collection = new Mock<IMongoCollection<UiCustomizationData>>();
var cursorMock = new Mock<IMongoCursor<UiCustomizationData>>();

сursorMock.Setup(m => m.GetEnumerator()).Returns(temp.GetEnumerator());

    接着：

    collection.Setup(m => /*Ваш запрос*/).Returns(cursorMock.Object);

    在新版本中，你需要模拟IAsyncCursor<T>，我试过这个（完整代码）：

    using System;
using System.Collections.Generic;
using System.Threading;
using MongoDB.Driver;
using Moq;

namespace ConsoleApplication6
{
  public class Program
  {
    private static void Main()
    {
      var temp = new List<UiCustomizationData>
      {
        new UiCustomizationData { Name = "1" },
        new UiCustomizationData { Name = "2" }
      };

      var coll = new Mock<IMongoCollection<UiCustomizationData>>();

      var cursorMock = new Mock<IAsyncCursor<UiCustomizationData>>();
      cursorMock.Setup(x => x.Current).Returns(temp);

      coll
        .Setup(x => x.FindAsync(It.IsAny<FilterDefinition<UiCustomizationData>>(), It.IsAny<FindOptions<UiCustomizationData>>(), It.IsAny<CancellationToken>()))
        .ReturnsAsync(() => cursorMock.Object);

      var r = coll.Object.FindAsync(x => x.Id == 1).Result;

      foreach (var item in r.Current)
      {
        Console.WriteLine(item.Name);
      }
    }
  }

  public class UiCustomizationData
  {
    public int Id;
    public string Name;
  }
}
