This book is a test-first exploration of software architecture in JavaScript. We will describe several patterns and practices, each time explaining what they are supposed to do by writing unit tests. Then, we will write the code to pass the tests. In this way, developers will not only learn techniques for structuring large-scale applications, but how to test their work.Given JavaScript's dynamic nature, thorough unit-test coverage is even more essential than in strongly typed languages like C# or Java. Our goal in this test-driven book is to model a practice that will lead to code that is verified to be correct initially, and has the test coverage to ensure that it stays correct during subsequent maintenance.Writing testable JavaScriptWriting more concise and elegant code by thinking in JavaScript rather than thinking in C# and writing JavaScriptSurveying the current landscape of JavaScript frameworks for testing, dependency injection and aspect-oriented programmingTesting the implementation and use of common design patternsTesting the use of advanced JavaScript featuresTesting conformance to your organization's coding standardsAll code will be available in Wiley's online site as well as in the text.
