+- `:rack` - For testing bot in webhooks-mode in non-Rails application.
+  It uses `rack-test` gem to POST requests to bot's endpoint.
+- `:poller` - Calls `.dispatch` directly on controller class.
+
+Pick the appropriate one, then require `telegram/bot/rspec/integration/#{type}`

+for each type in
+[telegram/bot/rspec/integration/](https://github.com/telegram-bot-rb/telegram-bot/tree/master/lib/telegram/bot/rspec/integration).

+session is stubbed (does not use configured store engine), and update is not serialized
+so it also supports mocks. This can be useful for unit testing, but should not be used as
+the default way to test the bot.

-Initialize with `bot = Telegram::Bot::Client.new(token, botan: 'botan token')`
-or just add `botan` key in `secrets.yml`:
-
-```yml
-  telegram:
-    bot:
-      token: bot_token
-      botan: botan_token
-```
-
-Access to Botan client with `bot.botan`.
-Use `bot.botan.track(event, uid, payload)` to track events.
-
-There are some helpers for controllers in `Telegram::Bot::Botan::ControllerHelpers`:
-
-```ruby
-class Telegram::WebhookController < Telegram::Bot::UpdatesController
-  include Telegram::Bot::Botan::ControllerHelpers
-
-  # This will track with event: action_name & data: payload
-  before_action :botan_track_action
-
-  def smth(*)
-    # This will track event for current user only when botan is configured.
-    botan_track :my_event, custom_data
-
-    # or get access directly to botan client:
-    botan.track(...)
-  end
-end
-```
-
-There is no stubbing for botan clients, so don't set botan token in tests.

 ### Async mode
 
 There is built in support for async requests using ActiveJob. Without Rails
 you can implement your own worker class to handle such requests. This allows:
