Re: [webkit-dev] what's important in layouttests?
hi,Dan, Oliver. If I want to take it into my project, what should I do? I do not understand this question. I want to write a simple browser with webkit. By posting this questin, I am wondering if I should also take the layouttest together with my browser project.___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] what's important in layouttests?
David, as far as I could understand your situation, you are not implementing a new Port of WebKit, so no support to a new toolkit or something. If that is the case, the existing platform you are using probably has layout tests already implemented. They are useful for regression tests mainly, among other stuff... 2009/6/29 David Jones ds...@163.com: hi,Dan, Oliver. If I want to take it into my project, what should I do?

As addition resources, look at http://webkit.org/quality/testwriting.html and http://trac.webkit.org/wiki/Writing%20Layout%20Tests%20for%20DumpRenderTree to get into this deeper Br On Thu, Jun 25, 2009 at 11:04 PM, Oliver Huntoli...@apple.com wrote: Hi Dave, On Jun 25, 2009, at 7:54 PM, David Jones wrote: I am confused about webkit's layouttests. 1.What's the layouttess used for?

The layout tests are used to detect unintended changes in engine behavior, which are typically regressions. Are they provided only for developers who want to create a browser with webkit to test if their browser behaves right? No. They do not test browsers, they only test the WebKit engine. They are used by everyone who makes code changes to WebKit to ensure that the changes do not introduce regressions. Adding new tests when fixing bugs makes it almost impossible for the bug to come back undetected. 2.The layouttests use Safari to run all the tests, right? No. The DumpRenderTree tool, which is part of the WebKit source tree, is used to run all of them. A script called run-webkit-tests drives DumpRenderTree. 3.I noticed some tests need an app server, how do they start one? Some tests use a local HTTP server. run-webkit-tests sets it up, but you can also use run-webkit-httpd to start the server independently. 4.Is layouttest only for Leopard? No. They are cross-platform. In some cases, the results differ depending on the platform. The LayoutTests directory includes expected test results for all tests. If a test has platform-specific results, they can appear in subdirectories of LayoutTests/platform. Cross- platform results live alongside the test.
