Unlike Django's testing framework, Selenium actually automates user interaction on a given website as if a real user is performing the actions. 今回は、Djangoで作ったWebアプリケーションをテストする方法について解説したいと思います。, についての解説を通して、今のテストの流行りであるSeleniumについても知っておきましょう。, これから学習するWebアプリケーションのテストとは、一体どのようなものなのでしょうか。普段使っているGoogleやYahoo、AmazonなどのWebアプリケーションは、とても多くの機能を持っています。それらの機能がしっかりと期待する動作をしてくれるかどうかを調べるのがテストです。, など、様々なテスト項目があります。これらの項目についてそれぞれ手動でテストをしていく方法もあります。しかし大規模なサイトではそれぞれのテストに対する項目が多すぎて、時間も労力も途方が無いものになってしまいます。, そこでテストを自動化するツールも出てきました。Pythonにはunittestというテスト自動化ツールが付属しています。今回はunittestを使って、DjangoのWebアプリケーションのテストを行っていきましょう。, ここからは実際にWebアプリケーションのテストを行っていきます。ここから動作させるコードやコマンドはすべてMacで実行したものになります。WindowsやLinuxで動かす場合は、コマンドを置き換えて見てください。, となっています。新しいバージョンでも動作するはずですが、もしも上手く行かなかったら、バージョンを合わせて試してみてください！, まずはDjangoの環境を整えましょう。Djangoはプロジェクトを作成して、その中にWebアプリケーションを作成するのが基本の流れになっています。まずは、プロジェクトを作りたいディレクトリに移動して、このコマンドを実行しましょう。, これでmySiteというディレクトリが出来上がります。次にmySiteディレクトリに移動して、このコマンドを実行しましょう。, これでmySiteプロジェクトの中に、myappというWebアプリケーションが出来上がりました。現在のディレクトリ構成はこのようになっています。, 次に、mySite/settings.pyのINSTALLED_APPSを編集していきます。, INSTALLED_APPSに、myappを追加しました。これでDjangoの下準備は出来ました。, modelsにPersonクラスを追加しました。次にこのコマンドを実行してマイグレーションファイルを作成します。, マイグレーションファイルなど、modelsについての解説はこちらの記事をご覧ください。, DjangoのユニットテストではPython付属のunittestを拡張したDjango独自のTestCaseクラスを使います。基本的な流れとしてはdjango.testをimportしてTestCaseを継承してテストケースを作っていきます。, myapp/tests.pyを編集して保存することで、ユニットテストとして実行することが出来ます。今回は先程作ったPersonのmodelsに登録されているレコードの数をユニットテストします。, これでユニットテストが実行できました。ここまでのことを振り返ってみましょう。myapp/tests.pyに書いたself.assertEqual関数の第二引数に指定した数と、レコードの数を確認してみてください。まだレコードには何も追加されていません。, そして第二引数とレコードに追加された数が同じなので、ユニットテストの結果に「OK」返ってきたことが分かるかと思います。このようにmyapp/tests.pyにテストケースを追加していくことで、それぞれのmodelsに対してユニットテストをしていくことが出来ます。, それぞれのテストケース（クラス）はいくつ追加しても構いませんが、TestCaseクラスを継承しましょう。また、テストケースの数が多くなってくる場合はmyapp/testsというディレクトリを作ってテストケースを分けて書くことで管理がしやすくなります。, Webアプリケーションのテストはunittestを使った方法だけではありません。テスト自動化の代表的なツールとしてSeleniumがあります。Seleniumは自動でブラウザを操作するためのツールです。, SeleniumはPythonのパッケージマネージャであるpipでインストールすることが出来ます。, また、各ブラウザ向けに配布しているドライバを使う必要があります。今回はChromeを想定して解説します。ドライバはこちらからダウンロード、インストールしましょう。, ここからは実際にSeleniumを使って、ブラウザを直接操作せずに www.sejuku.net にアクセスして見ようと思います。pythonを実行するディレクトリにchromedriverを置いておきましょう。, ターミナルを開いてPythonのコンソールを開きましょう。下のコマンドを1行づつ実行してみると、PythonでChromeが操作出来ることが分かるかと思います。, 無事に www.sejuku.net にアクセス出来たでしょうか。SeleniumではDOM（Document Object Model）と呼ばれるページの構造についてを知る必要があります。, DOMとはHTMLなどの文書のためのインターフェイスのことです。上のサンプルコードにある「t=browser.find_element_by_id('lst-ib')」では、IDでlst-ibというエレメント（要素）を探しています。, 今回はPythonのコンソールを使って一つ一つ確認しました。しかしこれらのファイルを.pyファイルにまとめることによって、しっかりと自動化することが出来ます。「テストを自動化する」という意味がよくわからなかった方も、Seleniumを使った方法でなんとなくは理解していただけましたか？, Djangoで作ったWebアプリケーションのテスト方法について解説しました。unittestはPythonに標準で付属しているので内部的な機能に特化しています。また多くの言語から使えるSeleniumはブラウザから動きを見ることが出来ます。, ちょっとした挙動のテストから実際のユーザーが実行すると思われる挙動まで、幅広くカバーできます。いまいちイメージがつかめない方はSeleniumを使ってみて、視覚的にテストについて実感していくと良いと思います。, 当プログラミングスクール「侍エンジニア塾」では、これまで6000人以上のエンジニアを輩出してきました。 It allows to write and execute selenium tests just as normal ones.
