    <p>I’m trying to implement on a very big and bloating system a framework to use unit testing, the main problem is that 70% of the system is implemented with static methods. Is how I’ve reached Moles, and I’m very confident that I will reach my goal (I’m quite near).</p> <p>The problem I have right now is that I’m trying to mole a static method with a Generic Parameter:</p> <pre><code>public static T ExecScalar&lt;T&gt;(IDbConnection cx, string commandText, IDbTransaction tx, IEnumerable&lt;IDbDataParameter&gt; parameters) </code></pre> <p>googling on the web I’ve found this forum message:</p> <p><a href="http://social.msdn.microsoft.com/Forums/uk/pex/thread/3faadca2-a26f-449c-942e-d800a6079e02" rel="nofollow">http://social.msdn.microsoft.com/Forums/uk/pex/thread/3faadca2-a26f-449c-942e-d800a6079e02</a></p> <p>that is exactly my problem, and there is suggested to read the manual at page 10.</p> <p>I’ve read the manual at page 10, but it’s talking about stubbing and not molling. I ‘ve tried to apply the described solution but if I put:</p> <pre><code>Ktcar.Cs.Dal.DB.Moles.MDALDB.ExecScalarIDbConnectionStringIDbTransactionIEnumerableOfIDbDataParameter&lt;int&gt; = delegate(IDbConnection conn, String command, IDbTransaction trx, IEnumerable&lt;IDbDataParameter&gt; parameters) </code></pre> <p>I get:</p> <p>“Only assignment, call, increment, decrement, and new object expressions can be used as a statement”</p> <p>I have also tried:</p> <pre><code>Ktcar.Cs.Dal.DB.Moles.MDALDB.ExecScalarIDbConnectionStringIDbTransactionIEnumerableOfIDbDataParameter&lt;T&gt; = delegate(IDbConnection conn, String command, IDbTransaction trx, IEnumerable&lt;IDbDataParameter&gt; parameters) </code></pre> <p>And I get the same error </p> <p>Or:</p> <pre><code>Ktcar.Cs.Dal.DB.Moles.MDALDB.ExecScalarIDbConnectionStringIDbTransactionIEnumerableOfIDbDataParameter = null; </code></pre> <p>And then I get:</p> <p>“Cannot assign to 'ExecScalarIDbConnectionStringIDbTransactionIEnumerableOfIDbDataParameter' because it is a 'method group'”</p> <p>please, can anyone helpme on how to mock a static method with Generic Type output?</p>

    1. COYour sample appears to be lacking slightly... shouldn't you have something like: Ktcar.Cs.Dal.DB.Moles.MDALDB.ExecScalarIDbConnectionStringIDbTransactionIEnumerableOfIDbDataParameter<int> = (IDbConnection conn, String command, IDbTransaction trx, IEnumerable<IDbDataParameter> parameters) => { int x = 0;/* assign a value to x */ return x; };

    2. COi've changed the delegate asignation to null to simplify, if I write your sentence, I get the same error. The compiler dosen't like the <int> after the name of the molling method.

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.
