Question

我试图在dotnetcore项目中设置Moq。我有一个从我的控制器调用的通用存储库。我想测试一下是用moq来设置呼叫。但是我收到了一个错误。

启动的通用存储库调用import numpy as np # an array can perform element wise calculations unlike lists. a, b = np.array([2,5,1,9]), np.array([4,9,5,10]) mean = (a + b)/2; print(mean) >>>[ 3. 7. 3. 9.5]为T为：

Room

来自public T GetSingle(Expression<Func<T, bool>> predicate, params Expression<Func<T, object>>[] includeProperties)的来电如下：

RoomController

模拟部分看起来像：

var room = _roomRepository.GetSingle(r => r.Id == id, ro => ro.Image);

但我一直都有错误：

roomRepositoryMock.Setup(c => c.GetSingle(It.IsAny<Expression<Func<Room, bool>>>(), It.IsAny<Expression<Func<Room, object>>>()))
                            .Returns<Room>(null);

其他帖子建议在RoomControllerTest.cs(62,55): error CS1503: Argument 1: cannot convert from 'method group' to 'Expression<Func<Room, bool>>' RoomControllerTest.cs(62,70): error CS1503: Argument 2: cannot convert from 'System.Linq.Expressions.Expression<System.Func<viten_i_senter_backend.Models.Room, object>>' to 'System.Linq.Expressions.Expression<System.Func<viten_i_senter_backend.Models.Room, object>>'之后添加()，但这没有帮助。

有什么想法吗？

Answer 1

params接受一个数组，因此更改第二个期望值以期望任何数组的表达式It.IsAny<Expression<Func<Room, object>>[]>()

roomRepositoryMock
    .Setup(c => c.GetSingle(It.IsAny<Expression<Func<Room, bool>>>(), It.IsAny<Expression<Func<Room, object>>[]>()))
    .Returns<Room>(null);

Moq dotnetcore - 无法转换为＆＃39;方法组＆＃39;到表达<func <room，bool =“”>＆gt;＆＃39;
