Moving Forward with JUnit 5

on YouTube ↗28m

" summary

JUnit 5 is a complete rewrite (no code reused) divided into three parts: Platform (TestEngine + Launcher for IDEs/Gradle), Jupiter (new API with annotations), and Vintage (runs JUnit 3/4). It adds dynamic test generation (DynamicTest factories), richer parameterized tests (CSV source and multiple value types), and a unified extension model that replaces runners/rules. Android integration exists via the third‑party Android JUnit5 Gradle plugin; instrumentation support is experimental and requires API 26+.
