In this post, I would like to outline the contribution I made to the fluent-nhibernate API open source project.  One of the features of the API is a fluent interface for creating the nhibernate configuration file for the ISessionFactory.  The ISessionFactory provides a few optional configuration properties.  An example of one these properties is  max_fetch_depth.

The max_fetch_depth property sets a maximum "depth" for the outer join fetch tree for single-ended associations (one-to-one, many-to-one).  A 0 disables default outer join fetching. 

After reviewing the way some of the other properties had already been set up.  I started with creating my first unit test to include this property.  Below is the unit test I created.

   1:  [Test]

   2:          public void Max_Fetch_Depth_should_set_property_value()

   3:          {

   4:              _config.MaxFetchDepth(2);

   5:              ValueOf("max_fetch_depth").ShouldEqual("2");

   6:          }

Then I implemented the following code for MaxFetchDepth.

   1:  public THIS MaxFetchDepth(int maxFetchDepth)

   2:          {

   3:              _values.Store(MaxFetchDepthKey, maxFetchDepth.ToString());

   4:              return (THIS)this;

   5:          }
