話しをしたいポイントは３つ。

• 条件分岐を避けましょう
• 一時変数の使い方に注意しましょう
• 状態の使い方に気を使いましょう

これを徹底することで、バグの入り込む余地を最小限に保つプログラミングをしましょう。

条件分岐を避けましょう

This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:

them0nk

#Model 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 
@user.errors[:username].should include("can't be blank")  # check for the error message 

#Rendering
response.should render_template(:index)

#Redirecting 
response.should redirect_to(movies_path)
