Hi all, I was trying to understand how the Layout tests are being done inWebkit. I went through the perl code 'run-webkit-tests' and found thatthe script is using a tool name ImageDiff(WebKit/WebKitBuild/Release/Programs/ImageDiff) .But I could not 'find'that tool in WebKit folder. As I understand that ImageDiff tool is necessary to do a pixel level diff for test images generated.I am looking at running individual tests using a small shell script ratherrunning all the tests at once. this will help me to know the underlyingthings. Please help.
ImageDiff is currently only implemented for Mac and Windows. It's not needed to run the standard regression tests. Pixel test results will differ between platforms and software versions, so there is a lot of manual work involved in verifying results when bringing up pixel results on a new platform. Focusing on text-only and render tree tests would provide much better bang for your buck than pixel test results.
