darwin,test: flaky test sequential/test-fs-watch #8045
Description
Version: HEAD of master (at commit 4c62892)
Platform: Darwin hermes.local 12.6.0 Darwin Kernel Version 12.6.0: Wed Mar 18 16:23:48 PDT 2015; root:xnu-2050.48.19~1/RELEASE_X86_64 x86_64
Subsystem: fs, fsevents
sequential/test-fs-watch persistently fails when run in close proximity to parallel/test-fs-watch-recursive because it picks up an event that was generated by the other test.
Standalone:
$ python tools/test.py sequential/test-fs-watch
[00:00|% 100|+ 1|- 0]: Done
In sequence:
$ python tools/test.py parallel/test-fs-watch-recursive sequential/test-fs-watch
=== release test-fs-watch ===
Path: sequential/test-fs-watch
assert.js:89
throw new assert.AssertionError({
^
AssertionError: 'newfile.txt' == 'watch.txt'
at FSWatcher.<anonymous> (/Users/bnoordhuis/src/v1.x/test/sequential/test-fs-watch.js:89:18)
at emitTwo (events.js:106:13)
at FSWatcher.emit (events.js:191:7)
at FSEvent.FSWatcher._handle.onchange (fs.js:1412:12)
Command: out/Release/node /Users/bnoordhuis/src/v1.x/test/sequential/test-fs-watch.js
[00:00|% 100|+ 1|- 1]: Done
Also happens with the tests flipped:
$ python tools/test.py sequential/test-fs-watch parallel/test-fs-watch-recursive
=== release test-fs-watch ===
Path: sequential/test-fs-watch
assert.js:89
throw new assert.AssertionError({
^
AssertionError: 'newfile.txt' == 'watch.txt'
at FSWatcher.<anonymous> (/Users/bnoordhuis/src/v1.x/test/sequential/test-fs-watch.js:89:18)
at emitTwo (events.js:106:13)
at FSWatcher.emit (events.js:191:7)
at FSEvent.FSWatcher._handle.onchange (fs.js:1412:12)
Command: out/Release/node /Users/bnoordhuis/src/v1.x/test/sequential/test-fs-watch.js
[00:00|% 100|+ 1|- 1]: Done
Dropping in another test makes the problem go away again:
$ python tools/test.py parallel/test-fs-watch-recursive parallel/test-fs-watch-encoding sequential/test-fs-watch
[00:00|% 100|+ 3|- 0]: Done
I didn't test on Windows, the other platform that supports recursive file watching.

I think this one has been an entry in my mind's "oh that pops up from time to time on my local machine, fortunately not in CI though so I'm going to ignore it entirely"
