Front-end Unit Testing with JavaScript | Danny Croft - Web Developer made in Wales but working in London 

PhantomJS is a headless WebKit with JavaScript API. CasperJS is a navigation scripting & testing utility that runs on top/alongside of PhantomJS. If you’re thinking “headless WebKit??!!?”, then it might be easier for you picture PhantomJS as a web inspector console that can be injected into any web page that you want, then accessed and used. CasperJS makes it alot easier for you to navigate around a web page testing as you go. To be fair, my explanations don’t do these two tools enough justice. Please visit http://phantomjs.org/ and http://casperjs.org/ for a better explanation and more advanced features that aren’t covered here.

JavaScript design patterns – Part 2: Adapter, decorator, and factory | Adobe Developer Connection

You have come to part 2 of this JavaScript Design Patterns series. It’s been a little while since part 1, so you might want to refresh yourself on the Singleton, Composite, and Facade patterns. This time around, you learn about the Adapter, Decorator, and Factory patterns.

Improve your XSLT 2.0 stylesheets with types and schemas

The type-awareand schema-aware features of XSLT 2.0 can greatly assist you when you debug a stylesheet, and improve stylesheetquality and robustness in handling all input data. Learn how to use type-aware and schema-aware XSLT 2.0 during the debugging and testing processto avoid common issueswith invalid paths, incorrect assumptionsabout data types, and cardinalities. Also, find examplesof XSLT stylesheets that contain errors that would notbe caughtifschema-aware featureswerenotin use, and discover how explicitly specifying types results in useful error messages.

Functional thinking: Functional design patterns, Part 3

The Gang ofFour’sInterpreter design pattern encourages extending a languageby building a new language from it. Most functional languages letyou extend the languagein a variety of ways, such as operator overloading and pattern matching. Although Java™ doesn’t permitanyofthesetechniques, next-generation JVM languages do, with varying implementation details. In this article, Neal Ford investigateshow Groovy, Scala, and Clojure realizethe intent of the Interpreter design pattern byallowing functional extensions in ways thatJava does not.
