    <p>Trying to unit test functions which access a entity framework. So i tried to put all the entity code into the test function below? However it stops at the Linq statement; obviously trying to access the database is too much drama for it. Maybe a work around would be too to create a replica database within the unit test function based on sql lite or compact;(Its not a big database anyways) then execution would not have to leave the test function? Is this possible and how would i implement it?</p> <pre><code>public void RetreiveKeyFnTest() { StegApp target = new StegApp(); // TODO: Initialize to an appropriate value string username = "david"; // TODO: Initialize to an appropriate value string password = "david1"; // TODO: Initialize to an appropriate value string ConnectionString = ConfigurationManager.ConnectionStrings["DatabaseEntities"].ToString(); var dataContext = new DatabaseEntities(ConnectionString); var user = dataContext.Users.FirstOrDefault(u =&gt; u.Username.Equals(username) &amp;&amp; u.Password.Equals(password)); Assert.IsNotNull(user); //target.RetreiveKeyFn(username, password); //Assert.IsInstanceOfType(target.RetreiveLogs,typeof(DataAccess)); //Assert.IsInstanceOfType(target.p); //Assert.IsNotNull(target.RetreiveLogs.AuthenitcateCredentials(username,password)); //Assert.Inconclusive("A method that does not return a value cannot be verified."); } </code></pre> <p>Below is the code i am trying to test:</p> <pre><code>public void RetreiveKeyFn(string username, string password) { BusinessObjects.User p = RetreiveLogs.AuthenitcateCredentials(username,password); if (p != null) { if (RetreiveLogs.RetreiveMessages(p.UserId) == null) { DisplayLogs.Text = "Sorry No messages for you recorded in Database, your correspondant might have chose not to record the entry"; } else { MessageBox.Show("LogId = " + RetreiveLogs.RetreiveMessages(p.UserId).LogId + "\n" + "UserId = " + RetreiveLogs.RetreiveMessages(p.UserId).UserId + "\n" + "Message Key = " + RetreiveLogs.RetreiveMessages(p.UserId).MessageKey + "\n" + "PictureId = " + RetreiveLogs.RetreiveMessages(p.UserId).PictureId + " Date &amp; time = " + RetreiveLogs.RetreiveMessages(p.UserId).SentDateTime); DisplayLogs.Visible = true; } } else { MessageBox.Show("Please enter your correct username and password in order to retreive either key, image or both from Databse"); } } </code></pre>

    1. COIf it stops at the Linq statement it has nothing to do with `Drama` it has to do with how you are coding probably .. can you perhaps provide an Exception that is being thrown , if any...?? also what is the value of `ConnectionString` when you debug this code..?

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.
