That's odd. You can run just that one test:

  cd subversion/tests/libsvn_fs
  ./fs-test 14

Does it always fail? What sort of filesystem are you using? Is it a
network filesystem?

If you have strace installed you can run:

  libtool --mode=execute strace ./locks-test 14 2>&1 | grep failure/write-lock

For a successful test the output should end:

  chmod("test-obtain-write-lock-failure/write-lock", 0444) = 0
  open("test-obtain-write-lock-failure/write-lock", O_RDWR|O_CLOEXEC) = -1 EACCES (Permission denied)
  open("test-obtain-write-lock-failure/write-lock", O_RDWR|O_CLOEXEC) = -1 EACCES (Permission denied)

When the test is working it makes the "write-lock" file readonly (the
chmod) and then two attempts to open it fail. In your case it appears
that the attempts to open the file do not fail.
