Inter-process ResourceLocks

[roded]

Hi,
I'm interested in the possibility of extending JUnit's ResourceLock mechanism not only for locking inside a single JVM process but for inter-process locking (we might have multiple JVM processes running JUnit tests on the same system with shared resources).

Is it currently possible to replace JUnit's LockManager implementation?
And even if it is possible, is this a good idea?

Thanks

Looking at the code, it's currently not possible to replace it.

junit5/junit-platform-engine/src/main/java/org/junit/platform/engine/support/hierarchical/NodeTreeWalker.java

Line 34 in 22a64e7

this(new LockManager());

If you need complex locking, I suggest that you write your own distributed lock manager (DLM) and use it in your tests either directly (programmatically) or via a custom extension.

Thanks for the reply @dhoard.
I would much rather use JUnit constructs for synchronization.

I wonder if the JUnit developers consider adding a feature allowing replacement of the LockManager to serve such a purpose.
