RESTful API サーバの自動テスト案

概要

fab コマンドを実行すると Webmachine サーバを起動して、その後 pytest 経由で requests による API テストを実行。その後 Webmachine を終了するというのを作ってみました。

まずはローカルで動かすためのコマンドです。

Webmachine のコード

https://github.com/voluntas/snowflake/tree/feature/webmachine

やってることはたいした事じゃ無いです。

1. snowflake のフォルダまで移動して make devrel を実行する
2. dev/snowflake/bin/snowflake start で Webmachine を起動する
3. snowpack (Webmachine のテストが入っているフォルダ) まで移動して py.test を実行する
4. 結果に関係なく snowflake のフォルダまで移動して Webmachine を終了する

実行結果

$ fab webmachine
