A practical guide to running tests in parallel using Gradle and JUnit 5. Covers configuring maxParallelForks and forkEvery properties in build.gradle, demonstrates that Gradle parallelizes at the test class level (not method level), and addresses common pitfalls including shared resource conflicts (solved via org.gradle.test.worker ID) and static state issues with Singletons (solved via forkEvery=1 to isolate JVM per class). Includes timing-based examples to visualize parallel execution behavior.
