Module: Assit::Config

Defined in:
lib/assit/config.rb

Overview

Helper module for the configuration Ths is used to load the Assit module. The following configuration options exist:

  • assit_disabled - If set it will completely disable the assertions

  • assit_action - Selects the action that will be executed if the assert fails

The Assit framework can be configured through environment variables or a config file (assit_config.rb) in the current load path.

If environment variables are used, the should have ALL UPPERCASE names, as ASSIT_DISABLED and ASSIT_ACTION.

Environment variables take precedence over the config file.

If no configuration is given, the module is configured automatically:

A Rails installation run in ‘production’ mode will have the assertions disabled.

A Rails installation in the other modes will use :raise as the default action.

Other scripts will use :raise if the $DEBUG flag is set, otherwise :log is used as the default action
