  1) My test does something

     Failure/Error: expect(actual).to eq(expected)

​

       Expected { customer: { person: #<Person:0x00007ffd699c9320 @name="Marty McFly, Jr.", @age=17>, shipping_address: { line_1: "456 Ponderosa Ct.", city: "Hill Valley", state: "CA", zip: "90382" } }, items: [{ name: "Fender Stratocaster", cost: 100000, options: ["red", "blue", "green"] }, { name: "Mattel Hoverboard" }] }

          to eq { customer: { person: #<Person:0x00007ffd699c9000 @name="Marty McFly", @age=17>, shipping_address: { line_1: "123 Main St.", city: "Hill Valley", state: "CA", zip: "90382" } }, items: [{ name: "Fender Stratocaster", cost: 100000, options: ["red", "blue", "green"] }, { name: "Chevy 4x4" }] }
