So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

• https://twitter.com/bterlson/status/1093624668903268352
• https://news.ycombinator.com/item?id=19102367

There are, however, a few problems:

• These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
• One of the solutions isn't quite valid (new super)

* **Takeaways**
    * Share test utilities
    * Use a lint rule when people don't follow best practices
        * Not sure this is worth the effort for us
* It's easy to start writing tests, it's hard to continuously maintain tests and consistently keep coverage high
* How do you test a module?
    * In isolation
    * With integrations
    * Mock integrations
    * Test app but mock external dependencies

Load lib files in production (Rails 5)

If you have your code defined in classes in lib/ folder you may have problems to load that code in production.

Autoloading is disabled in the production environment by default because of thread safety.

Change config/application.rb:

    config.autoload_paths << Rails.root.join("lib")
 config.eager_load_paths &lt;&lt; Rails.root.join("lib")
