在集成测试中设置测试数据的最佳策略是什么？

Question

我正在尝试为我的存储库实施集成测试，但在每次集成测试之前，我都选择了正确的策略来插入测试数据。

这就是我的存储库测试类的样子;

  [TestFixture]
  public class RealtyTest : ITest<IRealtyRepository>
  {
    public IUnitOfWork Uow { get; set; }

    public IRealtyRepository Repository { get; set; }

    public ITestEnvironment TestEnvironment { get; set; }

    [OneTimeSetUp]
    public void OneTimeSetup()
    {
        TestEnvironment = new RealtyTestEnvironment();
        TestEnvironment.Prepare();
    }

    [SetUp]
    public void Setup()
    {
        Uow = AppCore.Instance.RealtyUow;
        Uow.BeginTransaction();
        Repository = ((IRealtyUow)Uow).RealtyRepository;
    }

    [Test]
    public void should_get_realty_detail_by_id()
    {
        Realty realty = Repository.GetDetail(1);

        Assert.IsNotNull(realty.Firm);
        Assert.IsNotNull(realty.FirmUser);
        Assert.IsNotNull(realty.Category);
        Assert.IsNotNull(realty.SubCategory);
        Assert.IsNotNull(realty.Publish);
        Assert.IsNotNull(realty.ResIdence);
        Assert.IsNotNull(realty.Star);
        Assert.IsNotNull(realty.Floor);
        Assert.IsNotNull(realty.Heating);
        Assert.IsNotNull(realty.Fuel);
        Assert.IsNotNull(realty.BuildState);
        Assert.IsNotNull(realty.Usage);
        Assert.IsNotNull(realty.Credit);
        Assert.IsNotNull(realty.Register);
        Assert.IsNotNull(realty.Activate);
        Assert.IsNotNull(realty.District);
        Assert.IsNotNull(realty.District.County);
        Assert.IsNotNull(realty.District.County.City);
        Assert.IsNotNull(realty.District.County.City.Country);
    }

    [Test]
    public void should_get_realty_detail_all_by_id()
    {
       Realty realty = Repository.GetWithChilds(1);

        Assert.IsNotNull(realty.Firm);
        Assert.IsNotNull(realty.FirmUser);
        Assert.IsNotNull(realty.Category);
        Assert.IsNotNull(realty.SubCategory);
        Assert.IsNotNull(realty.Publish);
        Assert.IsNotNull(realty.ResIdence);
        Assert.IsNotNull(realty.Star);
        Assert.IsNotNull(realty.Floor);
        Assert.IsNotNull(realty.Heating);
        Assert.IsNotNull(realty.Fuel);
        Assert.IsNotNull(realty.BuildState);
        Assert.IsNotNull(realty.Usage);
        Assert.IsNotNull(realty.Credit);
        Assert.IsNotNull(realty.Register);
        Assert.IsNotNull(realty.Activate);
        Assert.IsNotNull(realty.District);
        Assert.IsNotNull(realty.District.County);
        Assert.IsNotNull(realty.District.County.City);
        Assert.IsNotNull(realty.District.County.City.Country);

        Assert.Greater(realty.Files.Count, 0);
        Assert.Greater(realty.Attributes.Count, 0);
    }

    [TearDown]
    public void TearDown()
    {
        if (Uow != null)
        {
            Uow.Rollback();
            Uow.Dispose();
        }
    }

    [OneTimeTearDown]
    public void OneTimeTearDown()
    {
        TestEnvironment.Rollback();
    }
}

正如您在OneTimeSetup（）方法上看到的那样，我在测试类中完成每个集成测试方法之后插入测试数据并删除OneTimeTearDown（）方法。 对于测试数据创建，我使用了NDbUnit库。

这是我的RealtyTestEnvironment类实现;

 public class RealtyTestEnvironment : ITestEnvironment
{
    private NDbUnitTest _database = null;

    public int TestRowCount { get; set; }

    public RealtyTestEnvironment()
    {
        TestRowCount = 1;
    }

    public void Prepare()
    {
        _database = new SqlDbUnitTest(TestSettings.HemlakTestDbConnection);
        _database.ReadXmlSchema(string.Format(@"{0}\HemlakDb\Hemlak.xsd", TestSettings.AppRootPath));
        _database.PerformDbOperation(DbOperationFlag.DeleteAll);

        GeneralTestDataBuilder generalDataBuilder = new GeneralTestDataBuilder();
        _database.ReadXml(generalDataBuilder.GetTestTypeStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);

        LocationTestDataBuilder locationDataBuilder = new LocationTestDataBuilder();
        _database.ReadXml(locationDataBuilder.GetTestCountryStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(locationDataBuilder.GetTestCityStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(locationDataBuilder.GetTestCountyStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(locationDataBuilder.GetTestDistrictStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);

        FirmTestDataBuilder firmDataBuilder = new FirmTestDataBuilder();
        _database.ReadXml(firmDataBuilder.GetTestFirmStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(firmDataBuilder.GetTestFirmUserStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);

        RealtyTestDataBuilder realtyDataBuilder = new RealtyTestDataBuilder();
        _database.ReadXml(realtyDataBuilder.GetTestRealtyStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(realtyDataBuilder.GetTestRealtyFileStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
        _database.ReadXml(realtyDataBuilder.GetTestRealtyAttributeStream(TestRowCount));
        _database.PerformDbOperation(DbOperationFlag.InsertIdentity);
    }

    public void Rollback()
    {
        if (_database != null)
        {
            _database.PerformDbOperation(DbOperationFlag.DeleteAll);
        }
    }
}

所以我选择了NDbUnit，但我觉得不舒服，因为项目的最后提交日期是3年前，需要花费太多精力来准备测试环境。

有些人使用Repository类本身来插入测试数据，所以现在我们使用Repository类来插入测试数据来测试那个Repository类？这对我没有意义。

- 您的方法是什么，如何插入测试数据以测试您的存储库？

- 我的实施怎么样，我应该继续使用Ndbunit吗？
