Pretty Result PrinterでPHPUnitのテストを見やすくする

Laravel PHPUnit 技術ブログ

どうも、くずきです。
今日は、PHPUnitを見やすくるPretty Result Printerを紹介したいと思います。

Pretty Result Printerとは

そもそも今のPHPUnitは結果が見辛かったりします。

PHPUnit 5.7.26 by Sebastian Bergmann and contributors.

.........................................F...........             53 / 53 (100%)

ここらへんを改善するためにできたのがPretty Result Printerで

このように、どこのテストがこけたのがざっくりと見やすくなる。

導入と実行

導入は簡単で、Laravelのcomposer.jsonに追加

    "require-dev": {
        "barryvdh/laravel-ide-helper": "^2.4",
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~5.7",
        "codedungeon/phpunit-result-printer": "^0.4.4",  // 追加
    },

使用方法は簡単で、phpunit.xmlに書いてもいいけどすぐ試すには

phpunit --printer=Codedungeon\\PHPUnitPrettyResultPrinter\\Printer

でさきほどの結果が得られる。

おまけ

Laravelの開発者であるTaylor Otwellがツイッターで次のLaravelのバージョンである5.6に入れるか検討してるみたい。
