    <p>I love SS but I'm scratching my head trying to unit test my business layer. I'm new to unit testing andmocking and been reading up on NSubstitute as this looks like a fun mocking layer.</p> <p>I have my file structure roughly like this:</p> <pre><code>MainAppHostProject* | -AppStart -AppHost &lt;-- standard apphost DtoProject* | -HelloWorldDto &lt;-- simple POCO to ServiceLayerProject* | -HelloWorldService &lt;-- service interface that merely passes/sends Dtos to/from business layer BusinessLayerProject* | -HelloWorldManager &lt;-- logic to construct response and this class extends 'Service' (letting me access Db, session, etc)...sidenote: maybe i shouldve called this a HelloWorldRepository? -CustomAuthProvider -CustomUserSession DaoProject* | -HelloWorldDao &lt;-- POCO of table structure </code></pre> <p>The Apphost points to the HelloWorldService assembly and registers the SQL Server database as standard.</p> <p>Everything actually works great and I have been able to build up the logic in a cleaner way. Unfortunately I wish to embark on unit testing BUT I dont know how to decouple the database. </p> <p>I tried to register a fake in memory database but then I think there's incompatibility issues with how I've used code to get identities etc in SQL Server vs SQLite ways.</p> <pre><code>// container.Register&lt;IDbConnectionFactory&gt;(c =&gt; new OrmLiteConnectionFactory(":memory:", false, SqliteOrmLiteDialectProvider.Instance)); // container.Register&lt;IDbConnectionFactory&gt;(c =&gt; new OrmLiteConnectionFactory(":memory:", false, SqlServerDialect.Provider)); </code></pre> <p>I just want to decouple and unit test. Any ideas please?</p> <p>***UPDATE</p> <pre><code>public class UnitTest1 { private Container container; [TestMethod] public void TestMethod1() { container = new Container(); // container.Register&lt;IDbConnectionFactory&gt;(new OrmLiteConnectionFactory(":memory:", false, SqliteDialect.Provider)); // sqlite didnt work so attempting with a real DB for now var connectionString = @"Data Source=.\SQLEXPRESS;Initial Catalog=XXX;Integrated Security=True"; container.Register&lt;IDbConnectionFactory&gt;(c =&gt; new OrmLiteConnectionFactory(connectionString, SqlServerDialect.Provider)); // dependencies are injecting ok container.RegisterAutoWiredAs&lt;FeedbackRepo, IFeedbackRepo&gt;(); // service is autowiring --&gt; leading to good injections container.RegisterAutoWired&lt;FeedbackService&gt;(); var service = container.Resolve&lt;FeedbackService&gt;(); service.SetResolver(new BasicResolver(container)); // unit test is working well var request = new DTO.FeedbackDto { Message = "test" }; bool result = service.Post(request); } } </code></pre> <p>At the moment trying to get 'Db' to stop being null in my derived Service classes.</p>

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.
