Quick one today. I was writing some code for Sitecore Computed Index fields recently, and it took me more Google Effort than I felt it should have to work out how to write unit tests with FakeDB to verify the code worked. If you want to do that without spending a while searching, the answer is pleasingly simple:
When you declare a computed field, the key method you’re implementing looks like this:
public override object ComputeFieldValue(IIndexable indexable)
{
}
But when you implement a test using FakeDb you’re dealing with Item
objects:
[TestMethod]
public void ClassUnderTest_Description_OfTheTestCase()
{
using (var db = ComputedFieldsFakeDb.Create())
{
var itm = Sitecore.Context.Database.GetItem("/sitecore/content/TheItemToIndex");
var sut = new ComputedFieldUnderTest();
var result = sut.ComputeFieldValue( /* what goes here to do the mapping? */ );
Assert.AreEqual("somevalue", result);
}
}
So what do you do to map the Item
into an IIndexable
?
Well, turns out it’s pretty trivial – There’s a type called SitecoreIndexableItem
which wraps an Item
to give you an IIndexable
:
var result = sut.ComputeFieldValue(new Sitecore.ContentSearch.SitecoreIndexableItem(itm));
Simple.
