Requiring facets in test-unit unit tests causes invalid assertions to pass. See the below code reference ``` require 'test/unit' require 'facets' class TestExample < Test::Unit::TestCase def test_hash assert_equal({'name' => 'left'}, {'name' => 'right'}) end end ``` The assertion passes even though the hashes are not equal. Commenting out the require for facets makes the assertion behave as expected. Using test-unit 3.3.0 and facets 3.1.0
