Embracing JUnit 5 with Eclipse

Writing good tests is as important as writing good code for mastering high-quality software development. The JUnit framework is one of the most valuable skills a developer can learn to achieve that. JUnit 4.0 was first released over a decade ago after the introduction of annotations in Java 5. The world of Java and testing has evolved a lot since then. To take advantage of the new features like lambda expressions in Java 8 and to support the advanced testing needs, JUnit 5 is emerging as the next generation test framework and is expected to be released during Q3 2017. Eclipse is embracing it by integrating the new features provided by JUnit 5 in its tooling support.

In this session, I will demo how to get started with JUnit 5 in Eclipse and how the new features in JUnit 5 blend with the existing functionality in Eclipse. Some of the features from JUnit 5 that you will see in action include:

Custom display names
Custom composed annotations
Lambda expressions for assertions and assumptions
Grouping assertions
Nested tests
Dependency injection for constructors and methods
Dynamic tests and containers
Implementing tests via interface default methods

This session is not intended to provide a deep dive into JUnit 5. Come here and get a glimpse of the goodies provided by Eclipse as part of its JUnit 5 support.
