Häufige Annahme

Configuring settings with Sinatra's set method replaces existing Hash configurations, stores Proc and lambda values as callable objects on the settings object, and passes form HTTP verb overrides through to DELETE and PUT route handlers by default.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• Sinatra::Base.set merges new Hash options into previous Hash settings rather than overwriting them, and evaluates Proc or lambda settings on every property access rather than returning the callable object.
• assert storing a parameterized lambda directly via set fails with ArgumentError on access unless wrapped in a proc returning the lambda
• assert zero-arity proc settings execute dynamically on every settings access, returning fresh values
• assert Sinatra::Base defaults method_override to false, ignoring _method form parameters unless enable :method_override is set
• assert Sinatra::Base captures environment at load time, ignoring post-require ENV['RACK_ENV'] mutations unless explicitly reconfigured with set :environment
• assert development environment enables host_authorization by default, returning 403 Forbidden for non-localhost Host headers
