单元测试Automapper配置文件

本文关键字：配置文件 Automapper 单元测试 | 更新日期: 2023-09-27 17:50:45

我确实希望在CreateMap方法中测试自定义逻辑。I do NOT想测试某些类型的映射是否存在

我该怎么做，或者我需要知道哪些类。我感谢文件中每一个提示。Automapper单元测试似乎非常罕见…

public class UnitProfile : Profile
{
   protected override void Configure()
   {
      // Here I create my maps with custom logic that needs to be tested
    CreateMap<Unit, UnitTreeViewModel>()
         .ForMember(dest => dest.IsFolder, o => o.MapFrom(src => src.UnitTypeState == UnitType.Folder ? true : false));
    CreateMap<CreateUnitViewModel, Unit>()
         .ForMember(dest => dest.UnitTypeState, o => o.MapFrom(src => (UnitType)Enum.ToObject(typeof(UnitType), src.SelectedFolderTypeId)));
   }
}

单元测试Automapper配置文件

这是配置测试的文档:http://docs.automapper.org/en/stable/Configuration-validation.html

你可以在这里看到一个例子:https://stackoverflow.com/a/14150006/1505426

Automapper配置文件的测试示例(我在版本10.0.0中使用Automapper，在版本3.12.0中使用NUnit):

RowStatusEnum 

namespace StackOverflow.RowStatus
{
    public enum RowStatusEnum
    {
        Modified = 1,
        Removed = 2,
        Added = 3
    }
}

MyProfile 

namespace StackOverflow.RowStatus
{
    using System;
    using System.Linq;
    using AutoMapper;
    public class MyProfile : Profile
    {
        public MyProfile()
        {
            CreateMap<byte, RowStatusEnum>().ConvertUsing(
                x => Enum.GetValues(typeof(RowStatusEnum))
                    .Cast<RowStatusEnum>().First(y => (byte)y == x));
            CreateMap<RowStatusEnum, byte>().ConvertUsing(
                x => (byte)x);
        }
    }
}

MappingTests 

namespace StackOverflow.RowStatus
{
    using AutoMapper;
    using NUnit.Framework;
    [TestFixture]
    public class MappingTests
    {
        [Test]
        public void AutoMapper_Configuration_IsValid()
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile<MyProfile>());
            config.AssertConfigurationIsValid();
        }
        [TestCase(1, ExpectedResult = RowStatusEnum.Modified)]
        [TestCase(2, ExpectedResult = RowStatusEnum.Removed)]
        [TestCase(3, ExpectedResult = RowStatusEnum.Added)]
        public RowStatusEnum AutoMapper_ConvertFromByte_IsValid(
            byte rowStatusEnum)
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile<MyProfile>());
            var mapper = config.CreateMapper();
            return mapper.Map<byte, RowStatusEnum>(rowStatusEnum);
        }
        [TestCase(RowStatusEnum.Modified, ExpectedResult = 1)]
        [TestCase(RowStatusEnum.Removed, ExpectedResult = 2)]
        [TestCase(RowStatusEnum.Added, ExpectedResult = 3)]
        public byte AutoMapper_ConvertFromEnum_IsValid(
            RowStatusEnum rowStatusEnum)
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile<MyProfile>());
            var mapper = config.CreateMapper();
            return mapper.Map<RowStatusEnum, byte>(rowStatusEnum);
        }
    }
}
