Call current_user in a Integration Test

example.md

require "test_helper"

class UserFlowsTest < ActionDispatch::IntegrationTest
  setup do
    @user = users(:one)
  end

  test "some test"
    sign_in @user
    post post_path, params: {
      post: {
        title: "A Sample Post"
        # This is better than calling @user.id because it ensures the user_id is actually being set through the current_user.
        # and more closely matches what happens in a browser.
        user_id: @controller.send(:current_user).id
      }
    }
  end
