Param is missing in rspec test - ruby-on-rails

Question

I have the following RSpec test defined:
test 'invalid signup information' do
get signup_path
assert_no_difference 'User.count' do
post users_path, params: { user: { name: '',
email: 'user#invalid',
password: 'foo',
password_confirmation: 'bar' } }
end
assert_template 'users/new'
end
And the following Controller:
class UsersController < ApplicationController
def new
#user = User.new
end
def create
#user = User.new(user_params)
if #user.save
redirect_to new_user_path
else
render :new
end
end
def show
#user = User.find(params[:id])
end
private
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
end
If I execute rake test I get the following error:
ERROR["test_invalid_signup_information", UserSignupTest, 0.35556070700022246]
test_invalid_signup_information#UserSignupTest (0.36s)
ActionController::ParameterMissing: ActionController::ParameterMissing: param is missing or the value is empty: user
app/controllers/users_controller.rb:23:in `user_params'
app/controllers/users_controller.rb:8:in `create'
test/integration/user_signup_test.rb:7:in `block (2 levels) in <class:UserSignupTest>'
test/integration/user_signup_test.rb:6:in `block in <class:UserSignupTest>'
The test runs without problems if i delete the require statement in user_params. But I do send a user - So why does it fail?

I do not if this is right but in my opinion, you created an integration test but should be a test controller.
See this example
# spec/controllers/contacts_controller_spec.rb
# rest of spec omitted ...
describe "POST create" do
context "with valid attributes" do
it "creates a new contact" do
expect{
post :create, contact: {name: 'test'}
}.to change(Contact,:count).by(1)
end
