Creating database entities for tests quickly becomes unmanageable as data models become more complex. Factory Girl allows us to quickly create records in our database that easily grow with our application.
Testing code creates more reliable and maintainable applications. Testing a complex app with multiple dependencies can be, well, complex. A common dependency that needs to be managed in a test environment is a database.
Integration tests describe a server’s overall behavior and capabilities. These tests can quickly expose failing systems, help developers isolate bugs and make server-sized refactors safer.
Integration tests describe a server’s overall behavior and capabilities. These tests can quickly expose failing systems, help developers isolate bugs and make server-sized refactors safer. In this screencast, we’ll show you how to configure the Chai HTTP extension with the existing test suite for the Chattrbox app.
Testing code creates more reliable and maintainable applications. When adding tests to an existing codebase, test coverage reports can help expose which parts of the app are untested. When creating a new test suite alongside a new app, test coverage reports can help guide the creation of valuable tests.
Testing code creates more reliable and maintainable applications. It’s not always a straightforward process, though. Stubs and spies give us more control of what we can test and how our code behaves when we test it.

Tight coupling between view controllers in your application can lead to difficult maintenance as you add and remove features. This video will explore how using Protocols can make our Dependency Injection more loosely coupled. This improves the flexibility of the code and makes our application easier to change.
UIStackViews are a relatively new addition to UIKit, appearing with iOS 9. They are quite useful because they eliminate the need for many Auto Layout constraints in common screen designs, making them easier to modify and maintain.
As View Controllers become more complex, the need to manage the state of the view becomes more important. In this video we will discuss how to use a state machine to manage our views state.
Sometimes your app design calls for a control design that isn't provided in UIKit. In this video, we draw one from scratch!
When you have a complex view controller view, sometimes it is helpful to break up the view into manageable chunks. In this video we will show how you can use container views to simplify the construction of certain layouts. After this video you will know when and how to use these container views in your applications.
While Android SDK provides the APIs for using SQLite databases, they force developers to write a lot of boilerplate code. Room solves this problem by creating the glue code that saves objects to SQLite and reads them into memory. In addition, it performs some compile-time checks to ensure correctness of SQL queries.

In this skill pack we'll add test coverage to a full-stack messaging app called ChattrBox. We'll show you a few tools you can use for testing and demonstrate how to configure them to build a test suite that is scalable and provides meaningful feedback about an application.
Ready to dive into the exciting world of tvOS apps? In this skill pack, we'll cover a few examples while introducing you to some fundamentals of programming tvOS applications. By the end of this screencast you'll have the skills needed to start building your own tvOS apps.
In this skill pack, you will learn how to set up and use Sketch for creating color themes, palettes, symbols, and more.
Here are a few sample screencsats to help you get started. View More →
In this screencast, we'll show you how to create a web service for tracking todos and we'll continue to build on this application throughout the rest of the series.
