Pylons+memcacheDB...忘れんうちにテスト記述

Pylonsはnoseというプログラムを使ってテストをする。本来はUnit Testに重きを置くのが好きなのだが、今回の方式ではPOPO(Plain Old Python Object)が相手なので特にやることがない。むしろ、コントローラが所望の動きをしているかどうかを確認することが大事になる。

まずはテスト用memcachedbの環境をPylonsに教える必要がある。PhoneBook/test.iniを以下のように記述。

#
# PhoneBook - Pylons testing environment configuration
#
# The %(here)s variable will be replaced with the parent directory of this file
#
[DEFAULT]
debug = true
# Uncomment and replace with the address which should receive any error reports
#email_to = you@yourdomain.com
smtp_server = localhost
error_email_from = paste@localhost

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 5000

[app:main]
use = egg:PhoneBook
full_stack = true
cache_dir = %(here)s/data
beaker.session.key = phonebook
beaker.session.secret = hogehogehoge

sqlalchemy.url = sqlite:///%(here)s/test.db
memcachedb.servers = 127.0.0.1:31201

→test.iniから起動される場合、memcachedbはポート31201のほうが呼ばれるようになる。

テストだが、以下の確認ができていればよかろう。

new...フォームが表示されていること
view...
- データが表示されていること
- 不正なidが渡されたり、Phone以外のクラスを表示しようとしたらエラー404になること。
create...
- データを格納し、viewに制御を渡すこと

これでPhoneBookディレクトリからnosetestsを実行。
