Тестирование компонентов Vue.js с помощью Jest
Тестирование компонентов Vue.js с помощью Jest
Краткое руководство по тестированию компонентов Vue.js с использованием Jest и официальной библиотеки Vue Test Utils.
О книге
Покупая эту книгу, вы помогате русскому переводу документации по Vue Test Utils оставаться в актуальном состоянии! Спасибо за поддержку!
Настоятельно рекомендую включить уведомления на электронную почту о новых версиях книги (я собираюсь добавить информацию про тестирование Vuex и Vue Router в будущем), так вы не пропустите важные обновления. При покупке книги я показал, где это можно сделать, смотрите скриншот.
Модульное тестирование в современных JavaScript-фреймворках на основе компонентов нелегко. Компоненты связаны друг с другом, а браузер добавляет слой пользовательского интерфейса, что делает всё настолько зависимым, когда как нам нужно тестировать компоненты изолированно. Мы хотим, чтобы тестовый набор был надёжным и быстро работал.
В этой книге вы узнаете, как легко тестировать компоненты Vue.js и использовать полнофункциональный фреймворк тестирования Jest вместе с официальный инструментом для тестирования Vue Test Utils. Эта книга покажет вам как тестировать стилей и структуру, а также поведение ваших компонентов во Vue.js. Вы увидите, как применять такие методы, как моментальные снимки, поверхностную отрисовку, модульную зависимость и псевдонимы модулей, чтобы сделать ваши тесты более стабильными и чистыми.

On Java 8
Bruce EckelBy the author of "Thinking in Java," covering version 8 of the Java programming language (with updates to Java 17). Intended for “dedicated beginners,” it doesn’t assume you know anything about programming and takes you through the material step-by-step. However, I assume you are able to figure things out. It’s not a “dummies” or “idiot’s” guide.
