Unit test the Automapper profiles

This is the documentation for configuration testing: http://docs.automapper.org/en/stable/Configuration-validation.html

You can see an example of it here: https://stackoverflow.com/a/14150006/1505426


An example of tests for Automapper profile (I used Automapper in version 10.0.0 amd NUnit in version 3.12.0):

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);
        }
    }
}
