Testing The Impossible

Dive into the internals of thoughtbot’s copycopter_client and discover how we test grizzly components such as:

• HTTP
• SSL
• Threads
• Mutexes
• Polling
• Forking
• Logging
• Caching
• Rails Engines

Also learn common strategies for testing applications that contain difficult-to-test components, as well as tools for regression testing, such as ensuring that your library will work across several versions of Rails.

Testing is a staple in the Ruby community, but there are certain small pieces of behavior that seem to be simply untestable. Trying to create complicated tests for only a few lines of code seems to be a waste of time, but introducing gaps in coverage leaves the entire application or library suspect. This talk will help you close those gaps and keep your coverage at 100% regardless of what ugly monsters rear their heads.
