Investigate flaky test-fs-readfile-tostring-fail on macOS #10742
Comments
On an idle machine, this test is fast. But it gets slow if I run multiple instances of it in parallel. I wonder if it should be moved to Vague benchmark: If I run 96 instances of this test simultaneously, it takes about 55 seconds to complete. If I run 96 instances of test-fs-readfile-empty.js simultaneously, it takes 2 seconds. test-fs-readfile-error.js: 7 seconds. test-fs-readfile-fd.js: 2 seconds. |
Test fails reliably in CI if 32 instances are run at once. (Might not even need that many.) https://ci.nodejs.org/job/node-stress-single-test/1101/nodes=osx1010/console Same job moved to sequential is reliable: https://ci.nodejs.org/job/node-stress-single-test/1102/nodes=osx1010/console Will submit a PR to move it. |
test-fs-readfile-tostring-fail is resource-intensive and is flaky in CI. Move to sequential tests so it is not competing for resources with other tests. Fixes: nodejs#10742

Flake is back (even in |
@refack Can you open a separate issue for things like this where the new failure is different (and likely unrelated) to the issue reported previously? The issue reported here is a timeout. The test was taking more than 60 seconds to run. The one you link to ls a different kind of failure and is very unlikely to be related. |
(I opened it as #16601.) |
This test just failed recently on an osx1010 node. It appears it just timed out?:
