Yii2 Application Development Cookbook - Third Edition

Unit testing with Atoum

Besides PHPUnit and Codeception, Atoum is a simple unit testing framework. You can use this framework for testing your extensions or for testing a code of your application.

   { "name": "book/cart", "type": "yii2-extension", "require": { "yiisoft/yii2": "~2.0" }, "require-dev": { "atoum/atoum": "^2.7" }, "autoload": { "psr-4": { "book\\cart\\": ...
