JUnit 5 - Shaping the Future of Testing on the JVM

Explore the future of testing on the JVM with JUnit 5 in this Spring I/O 2016 conference talk by core committer Sam Brannen. Discover the inspiration behind and architecture of JUnit 5, focusing on Java 8, modularity, extensibility, and a modern programming API for authoring tests. Learn about the new programming model, including dependency injection via flexible method signatures, conditional test execution, lambda expressions and method references in assertions and assumptions, and implementing test methods using interface default methods. Dive deep into JUnit 5's extension model, understanding how to create and register extensions for conditional tests, method parameter resolution, and lifecycle callbacks. Gain insights into the Launcher API, TestEngine API, and Spring support for JUnit 5. Understand the roadmap, what's missing, and how to provide feedback for this pivotal testing framework.
