This is because the WebView remains open across tests and maintains a pointer to the WebViewHost. The use of placement new makes it difficult to add new mocks such as DeviceOrientationClientMock (see bug ...) to the WebViewHost, because the WebView's page controllers maintain pointers to their respective clients, which indirectly point back to the mocks. For this reason, the mock clients must keep their addresses across calls to WebViewHost::reset(). If we keep the placement new dance, we will have to add code such as: PassOwnPtr deviceOrientationClientMock = m_deviceOrientationClientMock.release(); ... this->WebViewHost(); new (this) WebViewHost(shell) ... m_deviceOrientationClientMock = deviceOrientationClientMock; This seems quite cumbersome, so I propose resetting the member variables that need it instead (patch attached). Alternatively, we could completely destroy both the WebView and the WebViewHost and create fresh ones for each test. However, doing that might slow down the test suite, as well as change the way that tests can interfere with each other, possibly reducing the number of bugs that we can discover. 305274 2 73064 jknotten 2010-11-05 07:36:43 -0700 Created attachment 73064 Patch 305788 3 73064 tkent 2010-11-06 06:55:58 -0700 Comment on attachment 73064 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=73064&action=review > WebKitTools/DumpRenderTree/chromium/WebViewHost.cpp:1111 > + m_policyDelegateEnabled = false; > + m_policyDelegateIsPermissive = false; > + m_policyDelegateShouldNotifyDone = false; > + m_topLoadingFrame = 0; > + m_pageId = -1; > + m_lastPageIdUpdated = -1; > + m_hasWindow = false; > + m_inModalLoop = false; > + m_smartInsertDeleteEnabled = true; > +#if OS(WINDOWS) > + m_selectTrailingWhitespaceEnabled = true; > +#else > + m_selectTrailingWhitespaceEnabled = false; > +#endif > + m_blocksRedirects = false; > + m_requestReturnNull = false; > + m_isPainting = false; > + m_canvas.clear(); We had better reset the followings too: m_pendingExtraData m_resourceIdentifierMap m_currentCursor m_windowRect m_clearHeaders m_editCommandName m_editCommandvalue m_paintRect Some of them don't need to be reset.
