Exit after the first N crashes instead of running all tests
-h|--help Show this help message
--[no-]http Run (or do not run) http tests (default: $httpDefault)
--[no-]wait-for-httpd Wait for httpd if some other test session is using it already (same as WEBKIT_WAIT_FOR_HTTPD=1). (default: $shouldWaitForHTTPD)
-i|--ignore-tests Comma-separated list of directories or tests to ignore
--iterations n Number of times to run the set of tests (e.g. ABCABCABC)

--random Run the tests in a random order
--repeat-each n Number of times to run each test (e.g. AAABBBCCC)
--reverse Run the tests in reverse alphabetical order
--root Path to root tools build
--[no-]sample-on-timeout Run sample on timeout (default: $sampleDefault) (Mac OS X only)
-1|--singly Isolate each test case run (implies --nthly 1 --verbose)
--skipped=[default|ignore|only] Specifies how to treat the Skipped file
default: Tests/directories listed in the Skipped file are not tested
ignore: The Skipped file is ignored
only: Only those tests/directories listed in the Skipped file will be run
--slowest Report the 10 slowest tests
--ignore-metrics Ignore metrics in tests
--[no-]strip-editing-callbacks Remove editing callbacks from expected results
-t|--threaded Run a concurrent JavaScript thead with each test
--timeout t Sets the number of seconds before a test times out (default: $timeoutSeconds)
--valgrind Run DumpRenderTree inside valgrind (Qt/Linux only)
-v|--verbose More verbose output (overrides --quiet)
-m|--merge-leak-depth arg Merges leak callStacks and prints the number of unique leaks beneath a callstack depth of arg. Defaults to 5.
--use-remote-links-to-tests Link to test files within the SVN repository in the results.
-2|--webkit-test-runner Use WebKitTestRunner rather than DumpRenderTree.
