Bug 1534375 - Fix intermittent failure in tools/tryselect/test/test_presets.py, r?gbrown
(deleted), text/x-phabricator-request

A couple observations:

  • The intermittent only started appearing after a second preset was added in bug 1532809. This is why it didn't fail when I initially created it.
  • It happens while loading the cached taskgraph generated by |mach try fuzzy| and is due to invalid JSON

So I believe pytest is running these tests in parallel and one test is writing the cache while the other is reading or something like that. If this is the case, the fix is pretty simple. Should have an answer soon.

This makes sure this test doesn't actually generate tasks.
