Bug 202323 – Layout Test http/tests/cache-storage/cache-records-persistency.https.html is failing

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Truitt Savell]

The following layout tests are failing on Mac and iOS WK2

http/tests/cache-storage/cache-clearing-origin.https.html
http/tests/cache-storage/cache-origins.https.html
http/tests/cache-storage/cache-persistency.https.html
http/tests/cache-storage/cache-records-persistency.https.html

Probable cause:

These tests are failing in tandem together sense around r250350

Flakiness Dashboard:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fcache-storage%2Fcache-clearing-origin.https.html%20http%2Ftests%2Fcache-storage%2Fcache-origins.https.html%20http%2Ftests%2Fcache-storage%2Fcache-persistency.https.html%20http%2Ftests%2Fcache-storage%2Fcache-records-persistency.https.html

I was able to reproduce these failures together using a test list and bisection. I found that if you run http/tests/IndexedDB/storage-limit-2.https.html before these 4 tests they all fail.

Reproduction:
run-webkit-tests --root testbuild-250425 http/tests/IndexedDB/storage-limit-2.https.html http/tests/cache-storage/cache-clearing-origin.https.html http/tests/cache-storage/cache-origins.https.html http/tests/cache-storage/cache-persistency.https.html http/tests/cache-storage/cache-records-persistency.https.html --child-processes 1
