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
Autofixture for a List of Object that has a protected constructor and a factory method
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 被保护,上述测试失败。如果我让它 public 它有效,但我想让它受到保护。 class 还有 15 个我没有在这里列出的属性。我还想要列表中每个项目的两个 dateRanges 之间的 randmon 日期。
如何调用工厂的 Create 方法?我需要为每个 属性 定义 autoFixure 吗?
Ploeh.AutoFixture.ObjectCreationException : The decorated ISpecimenBuilder could not create a specimen based on the request: EMR.Entities.AbpAuditLogs. This can happen if the request represents an interface or abstract class; if this is the case, register an ISpecimenBuilder that can create specimens based on the request. If this happens in a strongly typed Build expression, try supplying a factory using one of the IFactoryComposer methods.
您可以通过将 .FromFactory(new MethodInvoker(new FactoryMethodQuery()))
添加到您的自定义来使上述测试通过:
fixture.Customize<TestObjectCode>(
c => c
.FromFactory(new MethodInvoker(new FactoryMethodQuery()))
.With(x => x.ExecutionTime, newDate)
.With(x => x.ConditionId, 1));
这两个 类 都在 Ploeh.AutoFixture.Kernel
命名空间中定义。
综上所述,您应该 。
