Angular 2 Test-driven Development, 2nd Edition

Book Description

Key Features

• Learn test-driven development (TDD) in JavaScript and see its power though clear examples
• Enhance your understanding with details on Karma and Protractor, and set up an Angular2 test suit with them
• A practical guide filled examples that focus on a wide range of testing techniques in a professional Angular2 application

Book Description

This is a complete guide that shows you testing techniques with Karma to perform unit testing and end-to-end testing with Protractor. It will show you how to optimize your Angular 2 development process using TDD techniques and ensure the final project is free of bugs.

We start by reviewing the TDD life cycle, TDD in the context of JavaScript, and various JavaScript test tools and frameworks. You will see how Karma and Protractor can make your life easier while running JavaScript unit tests. We will enable you to build a test suite for an Angular2 application and build a testable Angular2 medium-to-large scale application by handling REST API data.

Building on the initial foundational aspects, we move on to testing for multiple classes, partial views, location references, CSS, and the HTML element. In addition, we will explore how to use a headless browser with Karma. We will also configure a Karma file to automate the testing and tackle elements of Angular2 (components, services, classes, and broadcasting) using TDD.

Finally, you will find out how to pull data using an external API, set up and configure Protractor to use a standalone Selenium server, and set up Travis CI and Karma to test your application.

What you will learn

• Get a clear overview of TDD in the context of JavaScript with a brief look at testing techniques, tools, and frameworks
• Get an overview of Karma and Protractor and create test suites for an Angular2 application with them
• Understand automated testing and implement headless automated tests with Karma
• Implement the testing techniques with mocks, broadcast events, and asynchronous behavior
• Integrate REST-based services and APIs into an application to extract data
• Automate Karma unit tests with Travis CI

书名：Angular 2 Test-driven Development, 2nd Edition

Key Features

• 学习测试驱动的开发(TDD)，并通过清晰的示例了解它的威力
• 通过Karma和量角器的细节加深您的理解，并与他们一起设置Angular2测试服
• 该实用指南充满了专注于专业Angular2应用中的各种测试技术的示例

Book Description

这是一个完整的指南，向您展示了使用Karma执行单元测试和使用量角器进行端到端测试的测试技术。它将向您展示如何使用TDD技术优化您的角度2开发过程，并确保最终项目没有错误。

我们首先回顾TDD生命周期、在JavaScript上下文中的TDD以及各种JavaScript测试工具和框架。您将看到Karma和Protractor如何在运行JavaScript单元测试时让您的工作变得更轻松。我们将使您能够为Angular2应用程序构建一个测试套件，并通过处理rest API数据构建一个可测试的Angular2中大型应用程序。

在最初的基本方面的基础上，我们将继续测试多个类、部分视图、位置引用、CSS和HTML元素。此外，我们还将探索如何在Karma中使用无头浏览器。我们还将配置一个Karma文件，以使用TDD自动化测试和处理Angular2的元素(组件、服务、类和广播)。

最后，您将了解如何使用外部API获取数据，如何设置和配置Protrator以使用独立的Selify服务器，以及如何设置Travis CI和Karma来测试应用程序。

你将学到什么

• 通过简要介绍测试技术、工具和框架，在Java环境中对TDD有一个清晰的概述
• 了解Karma和量角器的概述，并使用它们为Angular2应用程序创建测试套件
• 了解自动化测试并利用Karma实施无头自动化测试
• 使用模拟、广播事件和异步行为实现测试技术
• Integrate REST-based services and APIs into an application to extract data
• 使用Travis CI自动执行Karma单元测试
