Xunit 测试不适用于 mongodb 服务
Xunit test not working for mongodb service
我想做一个小的 XUnit 测试,但它不工作。 (AddTest
有效但 GetAllRestaurantsCountShouldReturnThree
无效。)
我是单元测试的新手,我不知道 Moq 以及如何使用它。
如何模拟我的 IMongoService
并获取餐厅数量?
MongoService.cs
public class MongoService : IMongoService
{
private readonly IMongoDatabase _mongoDatabase;
private readonly IMongoClient _mongoClient;
public MongoService()
{
_mongoClient = new MongoClient("mongodb://localhost:27017");
_mongoDatabase = _mongoClient.GetDatabase("Restaurant");
}
public List<RestaurantDto> GetAllRestaurants()
{
var collection = _mongoDatabase.GetCollection<RestaurantDto>("Restaurant");
return collection.Find(_ => true).ToList();
}
}
MongoServiceTest.cs
public class ReviewServiceTests
{
private List<RestaurantDto> _allRestaurants = new List<RestaurantDto>()
{
new RestaurantDto() {Name="xxx", ZipCode = "111" },
new RestaurantDto() {Name="yyy", ZipCode = "222" },
new RestaurantDto() {Name="zzz", ZipCode = "333" },
};
[Fact] //Not Working
public void GetAllRestaurantsCountShouldReturnThree()
{
var _mongoService = new Mock<IMongoService>();
_mongoService.Setup(x => x.GetAll()).Returns(_allRestaurants );
var count = _mongoService.GetAll(); //GetAll() not seeing
Assert.Equal(count, 3);
}
[Fact] //Working
public void AddTest()
{
Assert.Equal(10, Add(8, 2));
}
int Add(int a, int b)
{
return a + b;
}
}
您使用的最小起订量不正确
[Fact]
public void GetAllRestaurantsCountShouldReturnThree() {
var mock = new Mock<IMongoService>();
mock.Setup(x => x.GetAllRestaurants()).Returns(_allRestaurants);
IMongoService mongoService = mock.Object;
var items = mongoService.GetAllRestaurants(); //Should call mocked service;
var count = items.Count;
Assert.Equal(count, 3);
}
