我正在用C#编写集成测试,Db正在由Entity Framework6负责。我有测试的问题如果数据被添加到按键相关的2个表中时数据正确添加。
考虑:
Make Table - Id, name, YearId
Year Table - Id, CalenderYear
关系:
1 to many - 1 Year has n Make
这是我在Integration测试中的方法,我想测试是否可以成功添加到两个表:
[TestMethod]
[TestCategory("Integration")]
public void ApplicationsContext_AddMake_ShouldAddSuccessfully()
{
// Arrange.
var currentEntity = ApplicationsContext.Makes.ToList<Make>();
// Act.
var newYear = Fakes.GetNewYear();
ApplicationsContext.Years.Add(newYear);
ApplicationsContext.SaveChanges();
var newMake = Fakes.GetNewMake();
ApplicationsContext.Makes.Add(newMake);
ApplicationsContext.SaveChanges();
// Assert.
var entityAfterOperation = ApplicationsContext.Makes.ToList<Make>();
Assert.IsTrue(currentEntity.Count < entityAfterOperation.Count);
}
这是我的假班:
public static Year GetNewYear()
{
var newYear = new Year()
{
CalendarYear = 2015
};
return newYear;
}
public static Make GetNewMake()
{
var newMake = new Make()
{
Name = "Toyota",
Description = "This is Make Description",
};
return newMake;
}
这不起作用,因为我真的不知道如何发送年份ID? 这是我得到的错误:
{"Violation of UNIQUE KEY constraint 'UQ_Year_CalendarYear'. Cannot insert duplicate key in object 'Common.Year'. The duplicate key value is (2015).\r\nThe statement has been terminated."}
答案 0 :(得分:1)
您未将年份与年份相关联并在您将其添加到数据库时创建。
因此,在添加它们之前,您应该将newMake
添加到newYear
。
var newYear = Fakes.GetNewYear();
newYear.Makes.Add(Fakes.GetNewMake());
ApplicationsContext.Years.Add(newYear);
ApplicationsContext.SaveChanges();
在保存更改之前执行此操作时,两者都会一次性添加到数据库中。
