流利的NHibernate PersistenceSpecification组件和参考测试 [英] Fluent NHibernate PersistenceSpecification Component and Reference Tests
问题描述
1。 FNH不测试我的组件正确，我不知道为什么。
System.ApplicationException：预期
'DomainModel.Model.Publisher '
'DomainModel.Model.Publisher'
Property'Publisher'。
[TestMethod]
public void CanCorrectlyMapBook（）
{
new PersistenceSpecification< Book>（_ session）
.CheckProperty（p => p.Name， （p => p.IncludesCDDVD，true）
.CheckProperty（p => （p = Ip.Isbn，rder93q43949ewr）
.CheckProperty（p => p.IsLoaned，false）
.CheckProperty（p => p.Publisher，new Publisher（）{PublisherHomepage =www。 google.de，PublisherName =google}）
.VerifyTheMappings（）;
code
$ b $ p
$ b 2。
$ b
System.ApplicationException：预期的
'DomainModel.Model.Employee'但是得到了
'EmployeeProxyd6f94daa37c74be8b5ccccf40c5c23fa'
for Property'LoanedBy'。
[TestMethod]
public void CanCorrectlyMapBook（）
{
new PersistenceSpecification< Book>（_ session）
.CheckProperty（p => p.Name，My Book）
.CheckProperty（p => p.Id，1）
.CheckProperty（p => p.IncludesCDDVD，true）
.CheckProperty（p => p.Isbn，rder93q43949éwr）$ b $ CheckProperty（p => p.IsLoaned，false）
.CheckReference（p => p.LoanedBy，new Employee（）{EMail =，FirstName =Alex，LastName = Mueller}）
.VerifyTheMappings（）;
}
但是当我测试这个手动时，一切正常。
ISession mysession = Helper.CreateSessionFactory（false，false）.OpenSession（）;
Book myBook = new Book（）
{
Author =Hesse，
IncludesCDDVD = true，
DateOfIssue = DateTime.Now，
Isbn = erwe0ri，
IsLoaned = true，
Name =My Book new，
Publisher = new Publisher（）{PublisherHomepage =www.google.de，PublisherName =google }，
Release = new Release（）{ReleaseDate = DateTime.Now，ReleaseNumber = 1}，
LoanedBy = new Employee（）{EMail =，FirstName =Alex，LastName =Mueller }
};
mysession.Save（myBook）;
mysession.Close（）;
mysession.Dispose（）;
我已经通过查找数据库来验证这一点...
PersistenceSpecification测试是针对内存数据库sqllite运行的，而我的手动test是针对Sql Server 2008运行的。
有没有人已经使用了FNH，并正确地测试了一个引用和一个组件？解决方案
我认为你需要实现object.Equals（）方法，或者实现一个IEqualityComparer，并在构造PersistenceSpecification时注入它。
例如：
public class A
{
private int Id {get;组; }
public virtual B B_Member {get;组; }
public class Map：ClassMap< A>
{
public Map（）
{
Id（x => x.Id）;
参考文献（x => x.B_Member）;
public class B
{
private int Id {get;组; }
公共虚拟字符串BString {get;组; }
public class Map：ClassMap< B>
{
public Map（）
{
Id（x => x.Id）;
Map（x => x.BString）;
///删除此方法使验证失败
public override bool Equals（object obj）
{
var lhs = obj为B;
if（lhs == null）return false;
return BString == lhs.BString;
$ b $测试
public void Verify（）
{
var fcfg = Fluently.Configure（）
。数据库（SQLiteConfiguration.Standard.UsingFile（testdb.sqldb））
.Mappings（mc =>
{
mc.FluentMappings.Add（typeof（A.Map）） ;
mc.FluentMappings.Add（typeof（B.Map））;
}）
.ExposeConfiguration（cfg => new SchemaExport（cfg）.Execute（true，true，false） ）;
var sess = fcfg.BuildSessionFactory（）。OpenSession（）;
新的PersistenceSpecification< A>（sess）
.CheckReference（x => x.B_Member，new B（）{BString =hi}）
.VerifyTheMappings ）;
Assert.Throws< ApplicationException>（
（）=> new PersistenceSpecification< A>（sess，new AlwaysFalseEqualityComparer（））
.CheckReference（x => x。 B_Member，new B（）{BString =az}）
.VerifyTheMappings（））;
$ b注意每个属性比较的相关FNH代码是（反射器的补码）：
$ b $ pre $ 内部虚拟无效CheckValue（对象目标）
{
bool areEqual;
object actual = this.property.GetValue（target，null）;
if（this.entityEqualityComparer！= null）
{
areEqual = this.entityEqualityComparer.Equals（this.propertyValue，actual）;
}
else
{
areEqual = this.propertyValue.Equals（actual）;
if（！areEqual）
{
抛出新的ApplicationException（string.Format（Expected {0}），但得到了'{1}'属性'{2 }'，this.propertyValue，actual，this.property.Name））;
$ / code $ / pre
当然，这个异常似乎与你所体验。
I have two problems.
1 . FNH does not test my component correcty and I dont know why.
System.ApplicationException: Expected
'DomainModel.Model.Publisher' but got
'DomainModel.Model.Publisher' for
Property 'Publisher'.
[TestMethod]
public void CanCorrectlyMapBook()
{
new PersistenceSpecification<Book>(_session)
.CheckProperty(p => p.Name, "My Book")
.CheckProperty(p=> p.Id, 1)
.CheckProperty(p=>p.IncludesCDDVD, true)
.CheckProperty(p=>p.Isbn, "rder93q43949éwr")
.CheckProperty(p=>p.IsLoaned, false)
.CheckProperty(p=>p.Publisher, new Publisher(){PublisherHomepage = "www.google.de", PublisherName = "google"})
.VerifyTheMappings();
}
}
2 . FNH does not test my reference correctly.
System.ApplicationException: Expected
'DomainModel.Model.Employee' but got
'EmployeeProxyd6f94daa37c74be8b5ccccf40c5c23fa'
for Property 'LoanedBy'.
[TestMethod]
public void CanCorrectlyMapBook()
{
new PersistenceSpecification<Book>(_session)
.CheckProperty(p => p.Name, "My Book")
.CheckProperty(p=> p.Id, 1)
.CheckProperty(p=>p.IncludesCDDVD, true)
.CheckProperty(p=>p.Isbn, "rder93q43949éwr")
.CheckProperty(p=>p.IsLoaned, false)
.CheckReference(p=>p.LoanedBy, new Employee(){EMail = "",FirstName = "Alex", LastName = "Mueller"})
.VerifyTheMappings();
}
But when I test this "manually" everything works fine.
ISession mysession = Helper.CreateSessionFactory(false, false).OpenSession();
Book myBook = new Book()
{
Author = "Hesse",
IncludesCDDVD = true,
DateOfIssue = DateTime.Now,
Isbn = "erwe0ri",
IsLoaned = true,
Name = "My Book new",
Publisher = new Publisher() { PublisherHomepage = "www.google.de", PublisherName = "google" },
Release = new Release() { ReleaseDate = DateTime.Now, ReleaseNumber = 1 },
LoanedBy = new Employee() { EMail = "", FirstName = "Alex", LastName = "Mueller" }
};
mysession.Save(myBook);
mysession.Close();
mysession.Dispose();
I have verify this by looking up in the datbase ...
The PersistenceSpecification Tests run against an in-memory database sqllite and my manual "test" runs against a Sql Server 2008.
Does anybody of you have used FNH and tested a reference and a component correctly?
解决方案 I think you either need to implement the object.Equals() method on the relevant entities, or implement an IEqualityComparer and inject it when you construct the PersistenceSpecification.
For example:
public class A
{
private int Id { get; set; }
public virtual B B_Member { get; set; }
public class Map : ClassMap<A>
{
public Map()
{
Id(x => x.Id);
References(x => x.B_Member);
}
}
}
public class B
{
private int Id { get; set; }
public virtual string BString { get; set; }
public class Map : ClassMap<B>
{
public Map()
{
Id(x => x.Id);
Map(x => x.BString);
}
}
/// remove this method to have the verification fail
public override bool Equals(object obj)
{
var lhs = obj as B;
if (lhs == null) return false;
return BString == lhs.BString;
}
}
[Test]
public void Verify()
{
var fcfg = Fluently.Configure()
.Database(SQLiteConfiguration.Standard.UsingFile("testdb.sqldb"))
.Mappings(mc =>
{
mc.FluentMappings.Add(typeof (A.Map));
mc.FluentMappings.Add(typeof (B.Map));
})
.ExposeConfiguration(cfg => new SchemaExport(cfg).Execute(true, true, false));
var sess = fcfg.BuildSessionFactory().OpenSession();
new PersistenceSpecification<A>(sess)
.CheckReference(x => x.B_Member, new B() {BString = "hi"})
.VerifyTheMappings();
Assert.Throws<ApplicationException>(
() => new PersistenceSpecification<A>(sess, new AlwaysFalseEqualityComparer())
.CheckReference(x => x.B_Member, new B() {BString = "az"})
.VerifyTheMappings());
}
Note also that the relevant FNH code for each property comparison is (compliments of reflector):
internal virtual void CheckValue(object target)
{
bool areEqual;
object actual = this.property.GetValue(target, null);
if (this.entityEqualityComparer != null)
{
areEqual = this.entityEqualityComparer.Equals(this.propertyValue, actual);
}
else
{
areEqual = this.propertyValue.Equals(actual);
}
if (!areEqual)
{
throw new ApplicationException(string.Format("Expected '{0}' but got '{1}' for Property '{2}'", this.propertyValue, actual, this.property.Name));
}
}
Certainly that that exception seems to match the ones you are experiencing.
