That would allow us to test broadcasting made with channel, e.g.:
```ruby
class ChatRelayJob < ApplicationJob
def perform_later(room, msg)
ChatChannel.broadcast_to room, message: msg
end
end
```
To test this functionality we need to know the underlying stream name
(to use `assert_broadcasts`), which relies on `channel_name`.
We had to use the following code:
```ruby
assert_broadcasts(ChatChannel.broadcasting_for([ChatChannel.channel_name, room]), 1) do
ChatRelayJob.perform_now
end
```
The problem with this approach is that we use _internal_ API (we shouldn't care about `channel_name` prefix
in our code).
With this commit we could re-write the test as following:
```ruby
assert_broadcasts(ChatChannel.broadcasting_for(room), 1) do
ChatRelayJob.perform_now
end
```
* Don't reimplement assert_raises
Also test what happens in case there's no explicit rejection.
* Avoid OpenStruct. Remove space beneath private.
* Simplify verification methods for code under test.
* Match documentation with other Rails docs.
Also remove mention of the custom path argument for now.
Unsure how useful that really is.
* Use Webpacker by default on new apps
* Stop including coffee-rails by default
* Drop using a js_compressor by default
* Drop extra test for coffeescript inclusion by default
* Stick with skip_javascript to signify skipping webpack
* Don't install a JS runtime by default any more
* app/javascript will be the new default directory for JS
* Make it clear that this is just for configuring the default Webpack framework setup now
* Start using the Webpack tag in the default layout
* Irrelevant test
* jQuery is long gone
* Stop having asset pipeline compile default application.js
* Add rails-ujs by default to the Webpack setup
* Add Active Storage JavaScript to application.js pack by default
* Consistent quoting
* Add Turbolinks to default pack
* Add Action Cable to default pack
Need some work on how to set the global consumer that channels will
work with. @javan?
* Require all channels by default and use a separate consumer stub
* Channel generator now targets Webpack style
* Update task docs to match new generator style
* Use uniform import style
* Drop the JS assets generator
It was barely helpful as it was. It’s no longer helpful in a Webpacked
world. Sayonara!
* Add app/javascript to the stats directories
* Simpler import style
Which match the other imports.
* Address test failures from dropping JS compilation (and compression)

* Fix shared generator tests.
* webpacker-default: Modify `ControllerGeneratorTest`
The JS assets generator was dropped. ref. 46215b1794
* Revert "Simpler import style". It's currently failing with an error of "TypeError: undefined is not an object (evaluating '__WEBPACK_IMPORTED_MODULE_2_activestorage___default.a.start')". Waiting for @javan to have a look.
This reverts commit 5d3ebb71059f635d3756cbda4ab9752027e09256.
* require webpacker in test app
* Add webpacker without making the build hang/timeout. (#33640)
* use yarn workspaces to allow for installing unreleased packages and only generate js/bootsnap when required
* no longer need to have webpacker in env templates as webpacker moved this config to yml file
* Fix rubocop violation
* Got the test passing for the running scaffold
* update expected lines of code
* update middleware tests to account for webpacker
* disable js in plugins be default to get the tests passing (#34009)
* clear codeclimate report issues
* Anything newer than currently released is good
* Use Webpacker development version during development of Rails
* Edge should get development webpacker as well
* Add changelog entry for Webpacker change
Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required

The hack was merged from action-cable-testing gem by mistake.
We don't need it in Rails 6.
(cherry picked from commit 92030ec4b4309835ed0e792229984a1f0a044cef)
ActionCable::Channel::TestCase provides an ability
to unit-test channel classes.
There are several reasons to write unit/functional cable tests:
- Access control (who has access to the channel? who can perform action and with which argument?
- Frontend-less applications have no system tests at all–and we still need a way to test channels logic.

If `env` is duped or otherwise not the same as the original `env` that was
generated at the top of rack middleware, it is impossible for the server hijack
proc to update the right `env` instance. Therefore, capturing the return value
is more reliable. This is the recommendation of the rack SPEC.
