Class: ActiveSpec::Specifications::PresenceSpecification

Inherits:
AttributesSpecification show all
Defined in:
lib/active_spec/specifications/presence_specification.rb

Overview

This specification will check that the values for each attribute are neither nil, or empty.

Example usage:

include ActiveSpec::Specifications

class Foo
  attr_accessor :bar
end

spec = PresenceSpecification.new(:bar)
foo = Foo.new
spec.satisfied_by?(foo) # returns false
foo.bar = ''
spec.satisfied_by?(foo) # returns false
foo.bar = 'baz'
spec.satisfied_by?(foo) # returns true

This works in the same way as the Rails validation macro validates_presence_of.
