We are currently running this expression
return x => x.ObjectType != null && x.ObjectType == "SERVICE"
&& x.Service.Id == searchValue;
Which works fine until we come to do a unit test with just mock and it fails with the following exception:
The operands for operator 'Equal' do not match the parameters of method 'op_Equality'
The part of the expression that fails is the null check. If I replace the expression with just the null check and do the following it fails:
_unitOfWork.Repository<Widgits, int>().FindAll(x => x.ObjectType != null);
Does anyone know why this would only cause a problem when Unit Testing?
