具有受保护的构造函数和工厂方法的对象列表的自动修复

public partial class TestObjectCode
{
    /// <summary>
    /// We don't make constructor public and forcing to create object using
    /// <see cref="Create"/> method.
    /// But constructor can not be private since it's used by EntityFramework.
    /// Thats why we did it protected.
    /// </summary>
    protected TestObjectCode() {}

    public static  TestObjectCode Create(
                    DateTime executiontime,
                    Int32 conditionid,
                    String conditionname)
    {
        var @objectToReturn = new TestObjectCode
        {

            ExecutionTime = executiontime,
            ConditionId = conditionid,
            ConditionName = conditionname
        };

        return @objectToReturn;
    }

    public virtual Int32 ConditionId { get; set; }

    public virtual String ConditionName { get; set; }

    public virtual DateTime ExecutionTime { get; set; }
}

测试：

[Test]
[TestCase("1/1/2015", "07/5/2016")]
public void Task Should_Filter_By_Date_Range_Only(string startDate, string endDate)
{
    //Arrange
    var startDateTime = DateTime.Parse(startDate);
    var endDateTime = DateTime.Parse(endDate);

    //get randomDate between two Dates
    TimeSpan timeSpan = endDateTime - startDateTime;
    var randomTest = new Random();
    TimeSpan newSpan = new TimeSpan(0, randomTest.Next(0, (int)timeSpan.TotalMinutes), 0);
    DateTime newDate = startDateTime + newSpan;

    var list = new List<TestObjectCode>();
    _fixture.AddManyTo(list);
    _fixture.Customize<TestObjectCode>(
        c => c
        .With(x => x.ExecutionTime, newDate)
        .With(x => x.ConditionId, 1)
        );
    _fixture.RepeatCount = 7;
    _fixture.AddManyTo(list);
}

由于_fixture.Customize和我的ctor被限制，以上测试失败。如果我将其公开，则可以，但是我希望将其发布。此类还有15个以上我没有在此处列出的属性。我也想为列表中的每个项目在两个dateRanges之间的一个randmon日期。

如何调用工厂的Create方法？我需要为每个属性定义自动修复吗？

Ploeh.AutoFixture.ObjectCreationException：装饰的ISpecimenBuilder无法基于以下请求创建标本：EMR.Entities.AbpAuditLogs。如果请求表示接口或抽象类，则可能发生这种情况；如果是这种情况，请注册一个ISpecimenBuilder，它可以根据请求创建标本。如果在强类型的Build表达式中发生这种情况，请尝试使用IFactoryComposer方法之一提供工厂。
