How are engineers changing the way they test applications? This new issue of the Java Magazine focuses on test-driven development. Some companies like Atlassian are moving the quality assurance responsibility entirely to developers.  The advanced features of JUnit, a simple framework to write repeatable tests, can greatly increase developer testing abilities. User interfaces require specialized testing tools; for example, TestFX is designed to test JavaFX applications. Browser based applications can be tested with Selenium against multiple web browser types and versions.

The articles about testing are:

• Test JavaFX apps with TestFX 
• Eight Greatly Underused Features of JUnit 
• Building and Automating a Functional test Grid 
• Stress Testing Java EE Applications 
• Think Like a Tester and Get Rid of QA 

In addition, you will find the articles about: 

• Kotlin: A Low Ceremony, High-Integration Language 
• Functional Programming in Java 
• Contexts and Dependency Injection 
• A First Look at Microservices 
• More Ideas to Boost Your Developer Career 

Due to recent JavaFX ports, you can now create Java client applications that can be deployed on desktop, laptop, and embedded systems, as well as on mobile devices such as smartphones and tablets. In this Java Magazine recent  article, Johan Vos explores the state of JavaFX on mobile devices, focusing on the Android platform.

As Vos explains, like Java, one of the key benefits of JavaFX is the 'write once, run anywhere' paradigm. Thanks to the JavaFX ports for mobile platforms, you can now package your JavaFX applications for deployment on iOS and Android devices. The runtime environments deal with platform-specific issues, enabling you to focus on application-specific needs.

The article walks through the process of creating an Android package based on JavaFX code. It also discusses how to combine Android-specific code and JavaFX code for those situations when you might need to do so. Also see the website for JavaFXPorts , which is an initiative from the Java Community for coordinating JavaFX porting efforts. Read the article
