使用EF和AutoMapper在ASP.NET Core中进行的一种集成测试 [英] A kind of integration testing in ASP.NET Core, with EF and AutoMapper

问题描述

我试图通过存储库(包括AutoMapper的使用)测试从ASP.NET Core Controller到数据库的路径.

I'm trying to test the path from my ASP.NET Core Controller to the DB, through repository which includes the usage of AutoMapper.

这是我的资料库:

using System;
using System.Linq;
using AutoMapper;
using DS.DTO.MasterData;
using DS.Utilities.DSExceptions;
using Microsoft.Extensions.Logging;
using Omu.ValueInjecter;

namespace DS.MasterData.Repositories
{
    public class PersonFactRepository : IPersonFactRepository
    {
        private readonly Database.MasterDataContext dbContext;
        private readonly ILogger<PersonFactRepository> logger;
        private readonly IMapper mapper;
        public PersonFactRepository(ILogger<PersonFactRepository> logger, Database.MasterDataContext dbcontext, IMapper mapper)
        {
            this.dbContext = dbcontext;
            this.mapper = mapper;
            this.logger = logger;
        }

        public PatientDto CreatePatient(CreatePatientDto inModel)
        {
            var dbPersonDim = mapper.Map<CreatePatientDto, Database.PersonDim>(inModel);
            var dbAddressDim = mapper.Map<CreatePatientDto, Database.AddressDim>(inModel);
            var dbPhoneDim = mapper.Map<CreatePatientDto, Database.PhoneDim>(inModel);

            var dbPersonFact = new Database.PersonFact { FactId = Guid.NewGuid() };

            dbPersonDim.PersonFact = dbPersonFact;
            dbAddressDim.PersonFact = dbPersonFact;
            dbPhoneDim.PersonFact = dbPersonFact;

            dbPersonDim.InitDates();
            dbAddressDim.InitDates();
            dbPhoneDim.InitDates();

            dbContext.SaveChanges();

            var returnVal = new PatientDto();
            returnVal.InjectFrom(dbPersonDim)
                     .InjectFrom(dbAddressDim)
                     .InjectFrom(dbPhoneDim);

            return returnVal;
        }
    }
}

我的AutoMapper配置:

My AutoMapper configuration:

public class AutoMapperConfig : Profile
{
    public AutoMapperConfig()
    {
        CreateMap<CreatePatientDto, Database.PersonDim>(MemberList.None).ReverseMap();
        CreateMap<CreatePatientDto, Database.AddressDim>(MemberList.None).ReverseMap();
        CreateMap<CreatePatientDto, Database.PhoneDim>(MemberList.None).ReverseMap();
    }
}

我的问题是如何将我的Mapper配置放入我的fakeMapper中?

My problem is how do I get my Mapper configuration into my fakeMapper?

var inMemDB = Fakes.FakeDB.DB;
var loggerCntl = Substitute.For<ILogger<Controllers.PatientController>>();
var loggerPersonFactRepo = Substitute.For<ILogger<Repositories.PersonFactRepository>>();

AutoMapper.IMapper fakeMapper = ????

var personRepo = new PersonFactRepository(loggerPersonFactRepo, inMemDB, fakeMapper);

我打算进行集成测试，因为我希望测试能够将数据发布到控制器，并测试正确的数据是否出现在正确的表中.

It's on purpose that I'm going for a integration test, as I want my test to be able to post data to the controller and test if the right data ends up in the right tables.

推荐答案

1. 创建映射器提供程序

1. Create a mapper provider

public class MapperProvider
{
    public MapperProvider() { 

    }
    public MapperConfiguration GetMapperConfig()
    {
        var mce = new MapperConfigurationExpression();
        mce.AddProfile<AutoMapperConfig>();
        var mc = new MapperConfiguration(mce);
        return mc;
    }
}

注册映射配置

Register the mapping config

AutoMapper.IMapper fakeMapper = new Mapper(new 
    MapperProvider().GetMapperConfig());
