流利的Nhibernate System.ApplicationException:对于属性"Id"，预期类型为"System.Int32"的"1"，但得到类型为"System.Int32"的"2" [英] Fluent Nhibernate System.ApplicationException : For property 'Id' expected '1' of type 'System.Int32' but got '2' of type 'System.Int32'

问题描述

您好，我正在为流利的Nhibernate编写单元测试，当我在isloation中运行测试时，它通过了，但是当我运行多个测试时，则通过了.或多次运行测试失败，并显示以下消息 System.ApplicationException:对于属性"Id"，预期类型为"System.Int32"的"1"，但得到类型为"System.Int32"的"2"

Hi I am writing unit tests for fluent Nhibernate, when I run the test in isloation it passes, but when I run multiple tests. or run the test more than once it starts failing with the message below System.ApplicationException : For property 'Id' expected '1' of type 'System.Int32' but got '2' of type 'System.Int32'

[TextFixture] 公共无效Can_Correctly_Map_Entity() {

[TextFixture] public void Can_Correctly_Map_Entity() {

        new PersistenceSpecification<UserProfile>(Session)
            .CheckProperty(c => c.Id, 1)
            .CheckProperty(c => c.UserName, "user")
            .CheckProperty(c => c.Address1, "Address1")
            .CheckProperty(c => c.Address2, "Address2")

}

推荐答案

我建议使用内存数据库测试映射，以便您可以仅将这些测试隔离在映射中.如果使用内存数据库，则可以将FluentConfiguration放在[TestInitialize](MSTest)或[SetUp](NUnit)方法中，并且每次都会从头开始在内存中创建数据库.这是一个示例:

I'd suggest testing your mappings using an in-memory database so that you can isolate these tests the mappings only. If you use an in-memory database, you can place the FluentConfiguration in the [TestInitialize] (MSTest) or [SetUp] (NUnit) method, and the db will be created from scratch (in memory) each time. Here's an example:

[TestInitialize]  
public void PersistenceSpecificationTest()  
{  
    var cfg = Fluently.Configure()  
        .Database(SQLiteConfiguration.Standard.InMemory().UseReflectionOptimizer())  
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<UserProfile>())  
        .BuildConfiguration();  

    _session = cfg.BuildSessionFactory().OpenSession();  
    new SchemaExport(cfg).Execute(false, true, false, _session.Connection, null);  
}  

然后您的测试应该在每次运行时都能正常运行

Then your test should work fine each time you run:

[TestMethod] 
public void CanMapUserProfile() 
{ 
    new PersistenceSpecification<UserProfile>(_session)     
        .CheckProperty(c => c.Id, 1)     
        .CheckProperty(c => c.UserName, "user")     
        .CheckProperty(c => c.Address1, "Address1")     
        .CheckProperty(c => c.Address2, "Address2")  
} 

在这种情况下，您需要使用SQLite以及System.Data.SQLite DLL，可以在这里找到:

You'll need to use SQLite in this scenario, along with the System.Data.SQLite DLL, which you can find here: http://sqlite.phxsoftware.com/
