org.jspecify.annotations.NullMarked

Support classes and base implementation for any org.junit.platform.engine.TestEngine that wishes to organize test suites hierarchically based on the org.junit.platform.engine.support.hierarchical.Node abstraction.

Interface Summary

Modifier and Type	Interface and Description
public interface	EngineExecutionContext Marker interface for an execution context used by a concrete implementation of `HierarchicalTestEngine` and its collaborators.
public interface	HierarchicalTestExecutorService A closeable service that executes test tasks.
public interface	Node< the type of `EngineExecutionContext` used by the `HierarchicalTestEngine` C extends EngineExecutionContext> A node within the execution hierarchy.
public interface	ParallelExecutionConfiguration Configuration to use for parallel test execution.
public interface	ParallelExecutionConfigurationStrategy A strategy to use for configuring parallel test execution.
public interface	ResourceLock A lock for a one or more resources.

Class Summary

Modifier and Type	Class and Description
pack-priv class	CompositeLock
pack-priv class	DefaultParallelExecutionConfiguration
public class	ExclusiveResource An exclusive resource identified by a key with a lock mode that is used to synchronize access to shared resources when executing nodes in parallel.
public class	ForkJoinPoolHierarchicalTestExecutorService A `ForkJoinPool`-based executor service that executes test tasks with the configured parallelism.
public abstract class	HierarchicalTestEngine< the type of `EngineExecutionContext` used by this engine C extends EngineExecutionContext> Abstract base class for all `TestEngine` implementations that wish to organize test suites hierarchically based on the `Node` abstraction.
pack-priv class	HierarchicalTestExecutor< the type of `EngineExecutionContext` used by the `HierarchicalTestEngine` C extends EngineExecutionContext> Implementation core of all `TestEngines` that wish to use the `Node` abstraction as the driving principle for structuring and executing test suites.
pack-priv class	LockManager
pack-priv class	NodeExecutionAdvisor
pack-priv class	NodeTestTask<C extends EngineExecutionContext>
pack-priv class	NodeTreeWalker
pack-priv class	NodeUtils
pack-priv class	NopLock No-op `ResourceLock` implementation.
public class	OpenTest4JAwareThrowableCollector Specialization of `ThrowableCollector` that treats instances of `TestAbortedException` as aborting.
public class	SameThreadHierarchicalTestExecutorService A simple executor service that executes all test tasks in the caller's thread.
pack-priv class	SingleLock
public class	ThrowableCollector Simple component that can be used to collect one or more instances of `Throwable`.
