How can I write integration minitest code for a Rails app with basic authentication?

Question

About this matter, Rails guides and Rails documentation both didn't work. I wrote something like this and ran it

class PlacesTest < ActionDispatch::IntegrationTest
  def test_places
    get root_url
    assert_response 200
  end
end

But I have this line on application_controller.rb file:

http_basic_authenticate_with name: "dhh", password: "secret"

https://guides.rubyonrails.org/testing.html#what-to-include-in-your-functional-tests

This link suggests kindly

If you followed the steps in the Basic Authentication section, you'll need to add the following to the setup block to get all the tests passing:

request.headers['Authorization'] = 
ActionController::HttpAuthentication::Basic.
  encode_credentials('dhh', 'secret')

But it didn't work. Following link also suggests the same thing:

https://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Basic.html

But still test didn't pass.

E

Error:
PlacesTest#test_places:
NoMethodError: undefined method `headers' for nil:NilClass
    test/integration/places_test.rb:6:in `setup'

Could you help me?

Accessing request in controller tests is no longer supported in Rails 5, since controller test classes are inheriting from ActionDispatch::IntegrationTest, while they were inheriting from ActionController::TestCase in Rails 4.

To set request header in controller tests, you need to do this:

get root_url, headers: { 'Authorization': ActionController::HttpAuthentication::Basic.encode_credentials('dhh', 'secret') }

Edit: The guides are out-dated, see also https://stackoverflow.com/a/52803443/7313509
