Stubbing an ActiveRecord::Relation object

spec.rb

# first we create an empty ActiveRecord::Relation object
relation = Model.where(attribute: value)

# then we make the relation stub the :[] method
# and return whatever values we need
relation.stub(:[]).and_return( Model.new({attrs: values})] )

# of course, we can make this too
# instead of the step above
record = double("Model", :foo => 'bar', :bar => 'baz')
relation.stub(:[]).and_return([record])

# last, we make our Model class stub the :where method
# and return the relation object we created
Model.stub(:where).and_return(relation)

# additionally we can have use case specific behavior
model_instance.stub(:method_or_scope_that_returns_collection) { relation }
