    <p>I've researched some information about techniques I could use to <strong>unit test a DbContext</strong>. I would like to add some <strong>in-memory data</strong> to the context so that my tests could run against it. I'm using Database-First approach.</p> <p>The two articles I've found most usefull were <a href="http://romiller.com/2010/09/07/ef-ctp4-tips-tricks-testing-with-fake-dbcontext/" rel="nofollow noreferrer">this</a> and <a href="http://refactorthis.wordpress.com/2011/05/31/mock-faking-dbcontext-in-entity-framework-4-1-with-a-generic-repository/" rel="nofollow noreferrer">this</a>. That approach relies on creating an IContext interface that both MyContext and FakeContext will implement, allowing to Mock the context.</p> <p>However, I'm trying to avoid using repositories to abstract EF, as <a href="http://jamesmckay.net/2011/03/abstracting-your-orm-is-a-futile-exercise/" rel="nofollow noreferrer">pointed</a> <a href="https://stackoverflow.com/questions/5488313/organizationally-where-should-i-put-common-queries-when-using-entity-framework-c/5488947#5488947">by</a> <a href="https://stackoverflow.com/questions/5625746/generic-repository-with-ef-4-1-what-is-the-point">some</a> people, since EF 4.1 already implements repository and unit of work patterns through DbSet and DbContext, and I really would like to preserve all the features implemented by the EF Team without having to maintain them myself with a generic repository, as I already did in other project (and it was kind of painful).</p> <p>Working with an IContext will lead me to the same path (or won't it?).</p> <p>I thought about <strong>creating a FakeContext that inherits from main MyContext</strong> and thus take advantage of the DbContext underneath it to run my tests without hitting the database. I couldn't find similar implementations, so I'm hoping someone can help me on this.</p> <p><strong>Am I doing something wrong, or could this lead me to some problems that I'm not anticipating?</strong></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.
