+ Do not send NetworkProcessProxy::LogTestingEvent message if we are not testing
+ https://bugs.webkit.org/show_bug.cgi?id=200360
+
+ Reviewed by Tim Horton.
+
+ Sending this message causes instantiation of the default WebsiteDataStore in the UIProcess,
+ which causes more memory to be used than is needed if we are browsing without the default WebsiteDataStore.
+
+ Covered by an API test.
