857616 - Investigate why mochitest-5 on Linux ignores all tests in layout/style

Status: NEW

(SeaMonkey :: Build Config, defect)

Description

[Frank Wein [:mcsmurf]]

I've noticed the mochitest-5 test on Linux runs quite few tests compared to the Windows and Mac platform (~6000 vs. ~170000). I've found out that Linux ignores all tests in layout/style/test, from the log files:
Linux log file: 0 INFO Running tests in tests/layout/tables/test, tests/layout/xul/base/test, tests/layout/xul/test, tests/modules/libjar/test/mochitest, tests/parser/htmlparser/tests/mochitest, tests/security/ssl/bugs, tests/security/ssl/mixedcontent, tests/security/ssl/stricttransportsecurity, tests/suite/browser/test, tests/toolkit/components/alerts/test, tests/toolkit/components/microformats/tests, tests/toolkit/components/passwordmgr/test, tests/toolkit/components/places/tests, tests/toolkit/components/prompts/test, tests/toolkit/components/satchel/test, tests/toolkit/components/url-classifier/tests, tests/toolkit/content/tests/widgets, tests/toolkit/mozapps/extensions/test, tests/toolkit/xre/test, tests/uriloader/exthandler/tests/mochitest, tests/widget/tests

(tests/layout/style/test is the first entry, the rest is the same).
