314 To run only a specific test (useful when developing a new feature), run:
315 ./complete-run t/100-fullscreen.t
323 Specifies which X11 display should be used. Can be specified multiple times and
324 will parallelize the tests:
326 # Run tests on the second X server
327 ./complete-run.pl -d :1
329 # Run four tests in parallel on some Xdummy servers
330 ./complete-run.pl -d :1,:2,:3,:4
332 Note that it is not necessary to specify this anymore. If omitted,
333 complete-run.pl will start (num_cores * 2) Xdummy instances.
337 Runs i3 under valgrind to find memory problems. The output will be available in
338 C<latest/valgrind-for-$test.log>.
342 Runs i3 under strace to trace system calls. The output will be available in
343 C<latest/strace-for-$test.log>.
345 =item B<--coverage-testing>
347 Exits i3 cleanly (instead of kill -9) to make coverage testing work properly.
351 Number of Xdummy instances to start (if you don’t want to start num_cores * 2
352 instances for some reason).
