Not that I know of. Is is really that hard to add one more line?
fake.SomeProperty = MockRepository.GenerateStub<PropertyType>();
I guess if you had a lot of properties, it might become cumbersome.
Then again, if you've got a lot of properties you're calling methods
on, they're probably an important part of the class you're testing and
you may want to set some expectations on them.
It is an interesting idea. I played around with trying to create an
extension method that would use reflection to recursively generate
stubs, but there's some tricky issues (like how to set a return value
on a read-only property without using a lambda). And the recursive
nature of the stubbing caused an issue too.
public static void StubDeep<T>(this T mock) where T:class
{
Type t = typeof (T);
foreach (var prop in t.GetProperties(BindingFlags.Public |
BindingFlags.Instance).Where(prop => !prop.PropertyType.IsSealed))
{
var subMock = MockRepository.GenerateStub(prop.PropertyType);
if (prop.CanWrite)
{
prop.SetValue(mock, subMock, new object[] {});
}
else
{
//TOOD: How to set up a Stub() on a just a 'Type'
// and a 'PropertyInfo'? I.e. no lambda.
//mock.Stub(m => m.Property).Return(subMock);
}
// this doesn't work as the typeof "subMock" is
// reported as "Object" inside StubDeep().
subMock.StubDeep();
}
}
There may be easy fixes for those two issues, but I haven't played
around much with reflection on generic types.
