Annotation Interface ResourceLock

@API(status=EXPERIMENTAL, since="5.3") @Retention(RUNTIME) @Target({TYPE,METHOD}) @Inherited @Repeatable(ResourceLocks.class) public @interface ResourceLock
@ResourceLock is used to declare that the annotated test class or test method requires access to a shared resource identified by a key.

The resource key is specified via value(). In addition, mode() allows you to specify whether the annotated test class or test method requires READ_WRITE or only READ access to the resource. In the former case, execution of the annotated element will occur while no other test class or test method that uses the shared resource is being executed. In the latter case, the annotated element may be executed concurrently with other test classes or methods that also require READ access but not at the same time as any other test that requires READ_WRITE access.

This annotation can be repeated to declare the use of multiple shared resources.

Since JUnit Jupiter 5.4, this annotation is inherited within class hierarchies.
