239 To run the whole testsuite on a reasonable number of Xdummy instances (your
240 running X11 will not be touched), run:
243 To run only a specific test (useful when developing a new feature), run:
244 ./complete-run t/100-fullscreen.t
252 Specifies which X11 display should be used. Can be specified multiple times and
253 will parallelize the tests:
255 # Run tests on the second X server
256 ./complete-run.pl -d :1
258 # Run four tests in parallel on some Xdummy servers
259 ./complete-run.pl -d :1,:2,:3,:4
261 Note that it is not necessary to specify this anymore. If omitted,
262 complete-run.pl will start (num_cores * 2) Xdummy instances.
266 Runs i3 under valgrind to find memory problems. The output will be available in
267 C<latest/valgrind-for-$test.log>.
271 Runs i3 under strace to trace system calls. The output will be available in
272 C<latest/strace-for-$test.log>.
274 =item B<--coverage-testing>
276 Exits i3 cleanly (instead of kill -9) to make coverage testing work properly.
280 Number of Xdummy instances to start (if you don’t want to start num_cores * 2
281 instances for some reason).
283 # Run all tests on a single Xdummy instance
284 ./complete-run.pl -p 1
