Overview

This cop checks for Sidekiq worker perform arguments that look like classes or modules. These cannot be serialized for Redis, and should not be used with Sidekiq.

Constants other than classes/modules are not flagged by this cop.

Examples:

# bad
MyWorker.perform_async(MyClass)
MyWorker.perform_async(MyModule)
MyWorker.perform_async(Namespace::Class)

# good
MyWorker.perform_async(MY_CONSTANT)
MyWorker.perform_async(MyClass::MY_CONSTANT)
