I think https://trac.webkit.org/changeset/188828 might be the culprit,
because it touches PlatformWebView code path in this revision interval.

Seems likely! I will look shortly.

It looks like we don't have a view yet when TestController::initialize tries to set some prefs (via resetPreferencesToConsistentValues).

This is OK on PLATFORM(COCOA) because we keep around a global WKWebViewConfiguration and use that when retrieving the WKPreferences. Maybe someone from EFL or GTK (who can actually test this) can do the same with the WKPageConfiguration?

I simply apply below fix in order to run layout test on EFL port.


--- a/Tools/WebKitTestRunner/TestController.cpp
+++ b/Tools/WebKitTestRunner/TestController.cpp
@@ -568,7 +568,11 @@ void TestController::ensureViewSupportsOptionsForTest(const TestInvocation& test
 void TestController::resetPreferencesToConsistentValues()

+#if PLATFORM(COCOA)
     WKPreferencesRef preferences = platformPreferences();
+#else
+    WKPreferencesRef preferences = WKPageGroupGetPreferences(m_pageGroup.get());
+#endif


EFL layout test begins to run again with this fix. However I'm not sure if this is correct fix for EFL and GTK. Tim, what do you think ?

I hope to fix EFL layout test and performance test as soon as possible. Tim, Ossy , please take a look this patch.

Please implement platformPreferences() in TestControllerEfl.cpp instead of adding more #ifdefs.

It seems GTK layout test also has been broken since r188828. Fix it too.

Aren't these lines unused? As far as I know there isn't this kind 
of platform. WK2 platforms are only Mac and iOS (Cocoa), EFL, GTK.

If so, this is unused code. I didn't know it. I'm sorry.

No problem, let me remove them in bug148467
