Setting this up took quite a bit of time and research for me, so just thought of sharing the learnings along the way that led to a working setup.

- Initial error that I was getting with running System tests in Rails 6

    ```ruby
    System test integration requires Rails >= 5.1 and has a hard dependency on a webserver and `capybara`, please add capybara to your Gemfile and configure a webserver (e.g. `Capybara.server = :webrick`) before attempting to use system tests.
    ```

    - since the error above says specify `Capybara` in the Gemfile, a part of my Gemfile looked like below:

        ```ruby
        group :development, :test do
          gem 'capybara', '~> 3.13'
          gem 'factory_bot_rails'
          gem 'pry-byebug'
          gem 'rspec-rails'
          gem 'shoulda-matchers'
          gem 'webdrivers'
        end
        ```

- **What didn't work for me:**
    - From an [official wiki guide](https://github.com/heartcombo/devise/wiki/How-To:-sign-in-and-out-a-user-in-Request-type-specs-(specs-tagged-with-type:-:request)) of testing sign in of a user with Devise for request type specs:
        - Context: Although the title says it's the guide for request type specs but since content of the wiki also said `This is the equivalent of declaring include Devise::Test::IntegrationHelpers in an system/feature spec or Rails system/controller test.` , I was trying this out with system specs & it didn't work for me
            - Why this guide didn't work fully for me?
                - It specifies the usage of tests of type `request` with this line of code: `config.include Devise::Test::IntegrationHelpers, type: :request` but that throws an error for me which says undefined method `sign_in`(please read below for more context on what the `sign_in` method is for) when running the required system spec. My exact setup: Rails 6.0.3.rc1, Ruby: 2.6.0, RSpec 3.9, Capybara 3.32.1

- **Solution**: Steps that properly setup System tests for me in Rails 6 using RSpec & Devise :
    - For the `sign_in` (if you are using user sign in using Devise) method you need to implement the below steps to get up and running with system tests in Rails 6
        - other general code required to make things for system tests with Rails 6
            - **Step 1**: Specify `gem 'webdrivers'` in your Gemfile(already included as shown above) Why?
                - It's required for System tests to work with Rails 6
                - More details [here](https://everydayrails.com/2019/04/09/chromedriver-helper-webdrivers.html)
            - **Step 2**: Specify the required driver for Capybara. Why?
                - This is required for System tests to work with Rails 6
                - required code to be placed in the `RSpec.configure do |config|` block of your `rails_helper.rb` file:

                    ```ruby
                      config.before(:each, type: :system) do
                        driven_by :selenium_chrome_headless
                      end
                    ```

                - Please note: this is just one of the drivers that can be used here, there's a possibility that this would also work with other Capybara drivers also
            - **Step 3**: Specify the below helpers in the `RSpec.configure do |config|` block of your `rails_helper.rb` to make sure that the `sign_in` method is used to login the user into your app before testing the specific feature of your app which requires a signed in user

                ```ruby
                config.include Devise::Test::IntegrationHelpers, type: :system
                config.include Warden::Test::Helpers
                ```
