RKMappingTest throws error when source object key value is null

[patr1ck]

Given an object Name:

{
"name":"foo"
"created_at": 1332880246, 
"updated_at": 1332880246, 
"value":null
}

and a mapping where:

[mapping mapKeyPath:@"value" toAttribute:@"value"];

The following test fails:

id parsedJSON = [RKTestFixture parsedObjectWithContentsOfFixture:@"name.json"];
RKMappingTest *test = [RKMappingTest testForMapping:nameMapping object:parsedJSON];

[test expectMappingFromKeyPath:@"value" toKeyPath:@"value"];
STAssertNoThrow([test verify], nil);

I dug into RestKit a bit and noticed that if the RKObjectMappingOperation skips the mapping if the value is null, so the test never finds the related mapping event.

Is this expected? Does it not make sense to want to test to make sure a null value is still null after mapping?

This is a good point. The null value should generating some kind of mapping event even if it requires an additional delegate callback to handle. Will take a look.
