    <p>I'm doing unit test(using NUnit) on Postgresql, unfortunately it causes an error:</p> <pre><code>Internal error RemotingException: Unix transport error. </code></pre> <p>Note: The error doesn't happen if I'm using Sqlite</p> <p>Code:</p> <pre><code> using System; using ncfg = NHibernate.Cfg; using System.Collections.Generic; using System.Reflection; using NHibernate; using System.Data; using NHibernate.Tool.hbm2ddl; using NHibernate.Dialect; using NHibernate.Driver; using NHibernate.ByteCode.LinFu; using NUnit.Framework; using NHibernate.Mapping; namespace RuntimeNhibernate { class MainClass { public static void Main (string[] args) { using(var c = new BlogTestFixture()) { c.CanSaveAndLoadBlog(); } } } public class InMemoryDatabaseTest : IDisposable { private static ncfg.Configuration Configuration; private static ISessionFactory SessionFactory; protected ISession session; public InMemoryDatabaseTest(Assembly assemblyContainingMapping) { if (Configuration == null) { Configuration = new ncfg.Configuration() .SetProperty(ncfg.Environment.ReleaseConnections,"on_close") .SetProperty(ncfg.Environment.Dialect, typeof (SQLiteDialect).AssemblyQualifiedName) .SetProperty(ncfg.Environment.ConnectionDriver, typeof(SQLite20Driver).AssemblyQualifiedName) .SetProperty(ncfg.Environment.ConnectionString, "data source=:memory:") .SetProperty(ncfg.Environment.ProxyFactoryFactoryClass, typeof (ProxyFactoryFactory).AssemblyQualifiedName) .AddAssembly(assemblyContainingMapping); /*Configuration = new ncfg.Configuration() .SetProperty(ncfg.Environment.ReleaseConnections,"on_close") .SetProperty(ncfg.Environment.Dialect, typeof (PostgreSQLDialect).AssemblyQualifiedName) .SetProperty(ncfg.Environment.ConnectionDriver, typeof(NpgsqlDriver).AssemblyQualifiedName) .SetProperty(ncfg.Environment.ConnectionString, "Server=127.0.0.1;Database=memdb;User ID=postgres;Password=password;Pooling=false;") .SetProperty(ncfg.Environment.ProxyFactoryFactoryClass, typeof (ProxyFactoryFactory).AssemblyQualifiedName) .AddAssembly(assemblyContainingMapping);*/ SessionFactory = Configuration.BuildSessionFactory(); } session = SessionFactory.OpenSession(); new SchemaExport(Configuration).Execute(true, true, false, session.Connection, Console.Out); } public void Dispose() { session.Dispose(); } }//class InMemory public class Blog { public virtual int BlogId { get; set; } public virtual bool AllowsComments { set; get; } public virtual DateTime CreatedAt { get; set; } public virtual string Subtitle { get; set; } public virtual string Title { get; set; } } [TestFixture] public class BlogTestFixture : InMemoryDatabaseTest { public BlogTestFixture() : base(typeof(Blog).Assembly) { } [Test] public void IsOK() { Assert.AreEqual(true, true); return; } [Test] public void CanSaveAndLoadBlog() { object id; using (var tx = session.BeginTransaction()) { id = session.Save(new Blog { AllowsComments = true, CreatedAt = new DateTime(2000,1,1), Subtitle = "Hello", Title = "World", }); tx.Commit(); } session.Clear(); Console.WriteLine("Hello {0}", id); using (var tx = session.BeginTransaction()) { var blog = session.Get&lt;Blog&gt;(id); Assert.AreEqual(new DateTime(2000, 1, 1), blog.CreatedAt); Assert.AreEqual("Hello", blog.Subtitle); Assert.AreEqual("World", blog.Title); Assert.AreEqual(true, blog.AllowsComments); tx.Commit(); } } }//Test }//namespace </code></pre> <p>What could be the possible reason when I unit test Postgresql, it results to <strong>RemotingException: Unix transport error.</strong> ?</p> <p>If I run the code outside of unit test (e.g. Main), it works. Btw, if I unit test Sqlite, it doesn't cause any errors too</p>

    1. COSounds like your program is trying to connect through a socket rather than a port. Can you configure the connector to use the Postgres TCP/IP port?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
