Course
Designing Interfaces in PHP
An interface is a type of contract that assures that certain abilities are available on on a particular object class. We'll write and extend multiple interfaces, then implement them to design and match functionality. Interfaces do not store any implementation details themselves. To share implementation details between classes, we harness the power of inheritance. Abstract classes prevent a parent class from being directly instantiated, while at the same time defining methods that MUST be implemented in any extending children. This course will combine interface contracts with class hierarchy to leverage the benefits of each concept. We'll explain the differences between interfaces and abstract classes, and give you the knowledge you need to build and implement both in your own projects.

Active Record Associations in Rails

Prototyping in the Browser
Before you design a website, it's important to have some kind of a plan or a wireframe to guide your efforts. But sometimes when you go from a simple sketch to digital pixels, the results aren't exactly what you expect. When you work with real HTML and CSS, and you're able to see your site on a real screens, you're able to see a more accurate representation of the final result. In this course, we're going to build a website prototype using the Bootstrap web framework.

Introduction to Selenium
As web applications grow in size it becomes difficult to reliably and thoroughly verify that the application behaves as intended. Manually stepping through the system gets tedious and time consuming. That's where automated testing tools become invaluable. In this course we will learn to use Selenium Webdriver, one of the most popular utilities for automating interactions with web browsers, to build automated tests for the purpose of verifying and maintaining a quality application.

Course
Building Services with ASP.NET Web API
Services expose data and processes through APIs (Application Programming Interfaces) implemented using common approaches or standards. Decoupling our back-end from our front-end makes it possible for our services to support multiple client apps. We can even allow other developers and organizations to consume and use our services to further broaden the reach of our applications. In this course, you'll learn how to use the ASP.NET Web API framework to build a RESTful service or HTTP API. As you learn about Web API, you'll create a service for the Fitness Frog single-page web app (SPA) developed using Angular.

Unit Testing in iOS
Unit testing allows you to test your application for logic errors, prevent crashes, and even write better code. In this course, we cover the philosophy behind unit testing, ways we can structure our code to make it more testable and look at tools we can use to test our code. We'll look at both tools that come built in, like the XCTest Framework in Xcode, as well as a few third party solutions for both Objective-C and Swift.
