Two users can not run-webkit-tests at once (due to use of /tmp) This comes up somewhat often @ Google because a lot of users use Windows or Linux boxes as their main desktop and just SSH into a mac to test patches & run the layout tests. Example failure: Running tests from /Projects/WebKit/LayoutTests Testing 10629 test cases. accessibility ....................could not create /tmp/layout-test-results/accessibility/plugin-stderr.txt
Turns out there is already: -o|--results-directory Output results directory (default: /tmp/layout-test-results) So I guess Julie and I just need to use that. Whether that should change to default to something else or not is a different question. :)
