            be { name.length >= 5 } not "name: 5 characters or more"
            be { name.length <= 10 } not "name: 10 characters or less"

        // {name=[name: 5 characters or more], age=[age: Over 20 years old]}
        val errors = validation.validate(user)

        Assert.assertEquals(errors["name"]!![0], "name: 5 characters or more")
        Assert.assertEquals(errors["age"]!![0], "age: Over 20 years old")
