This gem provides an
except method based on the
Rust method. It checks if an
object has a value different from
nil and raises an exception if it is equal
nil, with a custom message.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install object_expect
require 'object_expect' value = 1 puts value.expect('Should have a value') => 1 value = nil puts value.expect('Should have a value') => ObjectExpect::Error raised
