ITK doesn't recognize TEST: prefix, so you should use ENH: in the commit message. Otherwise looks good.

Updated the commit msg to use ENH

CI runs into: Error: No space left on device. We should maybe raise the memory available limit so that these tests do not run in the CI.

Maybe a better solution would be to remove temporary files (at least for tests creating large temporaries) immediately after the test is successfully finished. But this is a lot of additional work, and could be its own issue.

No space left on device

I have increased the memory limit to 16GB. I think this should suffice for now? Removing the temp files, as you said can be a separate issue to track and could be applied across all tests.

It ctest supported this option, it would avoid the additional work.

@bradking Does CTest support this? I suspect this would be interesting to other projects besides ITK.

CTest does not model the inputs or outputs of a test on disk. One would have to bake the cleanup into the tests themselves via wrapper scripts or similar.
