ActionCable::Channel::TestCase enhances ActionCable::TestHelper assertions (e.g.

To do this just use:
You need to set up your connection manually to provide values for the identifiers.

ActionCable::Channel::TestCase will automatically infer the channel under test

A list of all messages that have been transmitted into the channel.

An instance of the current channel, created when you call subscribe.

An ActionCable::Channel::ConnectionStub, representing the current HTTP connection.

# Asserts that the channel subscribes connection to a stream
assert subscription.confirmed?
# Asserts that the subscription was successfully created

For example:
transmitted messages, subscribed streams, etc.
2. Then, one asserts whether the current state is as expected. “State” can be anything:
1. First, one uses the subscribe method to simulate subscription creation.
Functional tests are written as follows:
