Learning Play! Framework 2

By: Andy Petrella

Overview of this book

<p>The Learning Play! Framework 2 has been created for web developers that are building web applications. The core idea is to focus on the HTTP features and to enable them through a simplification lens. Building a web application no longer requires a configuration phase, an environment setup, or a long development lifecycle - it's integrated!<br /><br />Learning Play! Framework 2 will enable any web developers to create amazing web applications taking advantage of the coolest features. It's the fastest way to dive into Play!, focusing on the capabilities by using them in a sample application. Although essentially Java based code, a Scala version is presented as well – giving an opportunity to see some Scala in action.<br /><br />After setting up the machine and learning some Scala, you will construct an application which builds from static to dynamic, before introducing a database. <br /><br />Then we'll focus on how data can be consumed and rendered in several ways. This will enable some real time communication through WebSocket and Server-Sent Event – on both server and client sides.</p> <p>The book will end with testing and deployment, which completes any web development project.</p>

Summary


In this chapter, we had an overview of all the testing phases using the bottom-up approach for various kinds and amounts of tested features. We also took the opportunity to review the helpers provided by Play! Framework 2 that enable us to focus on the tests themselves rather than the set up of the application components or tiers.

Since tests are a good starting point to learn Scala and to slightly introduce this language into an existing application, we preferred this language over Java to write our tests. But for those still preferring to stay in the pure Java world, you had enough information about the helpers provided by Play! 2. Furthermore, those helpers and mock-ups can be used along with any other Java testing framework you like.

There are plenty of amazing testing frameworks in Scala, however Play! 2 is particularly well integrated with specs2, so we followed this track too.

Based on this, we separated the tests into three main logical sets, namely atomic, applicative, and...
