An alternatie approach is to define a separate "can" ability for each permission.
def initialize(user)
user.permissions.each do |permission|
can permission.action, permission.object_type.constantize do |object|
object.nil? || permission.object_id.nil? || permission.object_id == object.id
end

The actual details will depend largely on your application requirements, but hopefully you can see how it's possible to define permissions in the database and use them with CanCan.

It is very easy to test the Ability model since you can call "can?" directly on it as you would in the view or controller.
def test "user can only destroy projects which he owns"
user = User.new
ability = Ability.new(user)
assert ability.can?(:destroy, Project.new(:user => user))
assert ability.cannot?(:destroy, Project.new)
end
