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>

Testing workflows


In this last section, we'll cover another level of tests that is able to test exposed features involving workflows crossing the atomic services provided by an application. This level of testing is also able to test interfaces opened to the wild, such as HTTP REST interfaces. These tests are probably the most important ones because they're asserting that our application is presenting features to the end user and these features are working well. That is, they are asserting that we've created added value to our application for the end user.

These kinds of tests are also the most difficult ones because they include third-party products or infrastructure components such as a browser and an HTTP server. However, we'll see that Play! Framework 2 is aware of these requirements, and it prepares everything for us in order to let us focus on the test logic only.

As in the preceding sections, several dedicated helpers are available for our tests. The first one is an overloaded version...
