Overview of this book

TypeScript is both a language and a set of tools to generate JavaScript. It was designed by Anders Hejlsberg at Microsoft to help developers write enterprise-scale JavaScript. Starting with an introduction to the TypeScript language, before moving on to basic concepts, each section builds on previous knowledge in an incremental and easy-to-understand way. Advanced and powerful language features are all covered, including asynchronous programming techniques, decorators, and generics. This book explores many modern JavaScript and TypeScript frameworks side by side in order for the reader to learn their respective strengths and weaknesses. It will also thoroughly explore unit and integration testing for each framework. Best-of-breed applications utilize well-known design patterns in order to be scalable, maintainable, and testable. This book explores some of these object-oriented techniques and patterns, and shows real-world implementations. By the end of the book, you will have built a comprehensive, end-to-end web application to show how TypeScript language features, design patterns, and industry best practices can be brought together in a real-world scenario.

Testing Typescript Compatible Frameworks

In Chapter 7, TypeScript Compatible Frameworks, we discussed TypeScript compatible frameworks, and explored how Backbone, Aurelia, Angular, and React use the MVC or the MV* design patterns to write models, views, and controllers. We implemented the same sample application in each of these frameworks, in order to be able to compare the similarities between them, and note the subtle differences. Then, in our last chapter, we started exploring test-driven development, and discussed the use of Jasmine as a test framework. We also explored using various test runners, including Testem and Karma, and finally explored Protractor for running integration, or end-to-end, tests.

In this chapter, we will essentially be combining our work from the previous two chapters, and will be discussing how to unit and integration test each of our TypeScript compatible...
