Overview of this book

Are you are looking for a better, more efficient, and more powerful way of building front-end web applications? Well, look no further, you have come to the right place! This book comprehensively integrates Angular version 4 into your tool belt, then runs you through all the new options you now have on hand for your web apps without bogging you down. The frameworks, tools, and libraries mentioned here will make your work productive and minimize the friction usually associated with building server-side web applications. Starting off with building blocks of Angular version 4, we gradually move into integrating TypeScript and ES6. You will get confident in building single page applications and using Angular for prototyping components. You will then move on to building web services and full-stack web application using ASP.NET WebAPI. Finally, you will learn the development process focused on rapid delivery and testability for all application layers.

Jasmine is an open source framework that is used to test JavaScript code without any dependency on DOM. As Angular is loosely coupled, we can use the Jasmine framework to test Angular components, services, and so on. Independent of each other, the clean syntax of Jasmine enables you to write tests very easily.

A global function named describe is the starting point of the Jasmine function. This global function takes a function and two parameters of type string. The string parameter describes the tests, and the function will have the actual implementation of testing:

describe("short description about the test suite", function() {

The first argument is the title of the test or spec, and the second argument is the function that tests the expectations by verifying the state of the code. Expectations are similar to assert in the Microsoft unit test framework. If any...
