From 9e25e0e1735f2ccca69679243aa8cf0885104164 Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Tue, 6 Oct 2015 08:51:14 -0600 Subject: Implement equality comparison on `AttributeSet` and friends Any gems or libraries which do work with serialization or YAML will ultimately need to compare these objects (albeit indirectly) to ensure correctness. These will likely never get used internally (as they're slow), but we should still expose them for others. --- activerecord/test/cases/attribute_set_test.rb | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'activerecord/test') diff --git a/activerecord/test/cases/attribute_set_test.rb b/activerecord/test/cases/attribute_set_test.rb index 5a0e463a48..7a24b85a36 100644 --- a/activerecord/test/cases/attribute_set_test.rb +++ b/activerecord/test/cases/attribute_set_test.rb @@ -239,5 +239,15 @@ module ActiveRecord assert_equal 2, new_attributes.fetch_value(:foo) assert_equal 3, new_attributes.fetch_value(:bar) end + + test "comparison for equality is correctly implemented" do + builder = AttributeSet::Builder.new(foo: Type::Integer.new, bar: Type::Integer.new) + attributes = builder.build_from_database(foo: "1", bar: "2") + attributes2 = builder.build_from_database(foo: "1", bar: "2") + attributes3 = builder.build_from_database(foo: "2", bar: "2") + + assert_equal attributes, attributes2 + assert_not_equal attributes2, attributes3 + end end end -- cgit v1.2.3
