Description Carlos Alberto Lopez Perez 2021-07-08 17:01:43 PDT

The following tests imported in 279585 are flaky:

Regressions: Unexpected text-only failures (8)
  imported/w3c/web-platform-tests/cookies/prefix/__host.document-cookie.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__host.document-cookie.https.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__host.header.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__host.header.https.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__secure.document-cookie.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__secure.document-cookie.https.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/__secure.header.html [ Failure ]
  imported/w3c/web-platform-tests/cookies/prefix/document-cookie.non-secure.html [ Failure ]


The flakiness happen due to same random integer that appears on the text results.

Example:

Run 1

-PASS __Host: Non-secure origin: 'Path=/;MaxAge=10'
+FAIL __Host: Non-secure origin: 'Path=/;MaxAge=10' assert_equals: `__Host-prefixtestcookie=0.47609837379802233` in `document.cookie` expected false but got true

Run 2:

-PASS __Host: Non-secure origin: 'Path=/;MaxAge=10'
+FAIL __Host: Non-secure origin: 'Path=/;MaxAge=10' assert_equals: `__Host-prefixtestcookie=0.4836850576033984` in `document.cookie` expected false but got true
