Minitest fails on user update test - ruby-on-rails

Question

My user#update method appears to be working as anticipated. When performing this method as requested from my front-end, a successful update occurs. The test for the method, however, fails.
For my test, I'm logging the user in, then attaching the returned auth_token in the request headers.
Here is the test:
test "should successfully update valid email" do
old = #user.auth_token
post api_login_url, params: { session: #credentials }
#user.reload
assert_not_equal old, #user.auth_token
old_user = #user
#request.headers["Authorization"] = #user.auth_token
patch "/api/users/" + #user.id.to_s, params: { email: "new#me.com", password: "testtest" }, headers: #request.headers
assert_response 201
assert_equal "new#me.com", User.find(#user.id).email
end
The error:
Expected: "new#me.com"
Actual: "test#woohoo.com"
In my controller (#user is already set):
before_action :authenticate_with_token!, only: [:update, :destroy]
before_action :set_user, only: [:show, :update, :destroy, :confirm, :posts, :comments]
wrap_parameters :user, include: [:username, :email, :password, :password_confirmation]
def update
if #user.update(user_params)
render json: #user
else
render json: #user.errors, status: :unprocessable_entity
end
end
def user_params
params.require(:user).permit(:username, :email, :password, :password_confirmation, :confirmation_code, :confirmed)
end
The user model:
require 'json_web_token'
class User < ApplicationRecord
before_save { email.downcase! }
before_create :generate_authentication_token!
before_update :reset_confirmed!, :if => :email_changed?
has_secure_password
has_many :posts
has_many :comments
has_many :votes
VALID_EMAIL_REGEX = /\A[\w+\-.]+#[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i
validates :email, presence: true, length: { maximum: 255 }, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
validates :username, presence: true, length: { maximum: 24 }, uniqueness: { case_sensitive: false }
validates :password, presence: true, length: { minimum: 8 }
validates :auth_token, uniqueness: true
def generate_authentication_token!
begin
self.auth_token = JsonWebToken.encode('id' => self.id, 'username' => self.username)
end while self.class.exists?(auth_token: auth_token)
end
def destroy_token!
self.auth_token = nil
end
def reset_confirmed!
self.confirmed = false
end
end
In case anyone will ask, I've tried removing the before_update :reset_confirmed! call.
I've tried rewriting the tests many different ways. The assert_response 201 does not fail.

You need to wrap your params:
patch "/api/users/" + #user.id.to_s,
params: { user: { email: "new#me.com", password: "testtest" }},
headers: #request.headers
I am however quite surprised you are not getting an exception (require(:user) should raise one when params[:user] is missing), so let me know if it is working.
