complete-run.pl - Run the i3 testsuite
|
||||
|
||||
=head1 SYNOPSIS
|
||||
|
||||
complete-run.pl [files...]
|
||||
|
||||
=head1 EXAMPLE
|
||||
|
||||
To run the whole testsuite on a reasonable number of Xdummy instances (your
|
||||
running X11 will not be touched), run:
|
||||
./complete-run.pl
|
||||
|
||||
To run only a specific test (useful when developing a new feature), run:
|
||||
./complete-run t/100-fullscreen.t
|
||||
|
||||
=head1 OPTIONS
|
||||
|
||||
=over 8
|
||||
|
||||
=item B<--display>
|
||||
|
||||
Specifies which X11 display should be used. Can be specified multiple times and
|
||||
will parallelize the tests:
|
||||
|
||||
# Run tests on the second X server
|
||||
./complete-run.pl -d :1
|
||||
|
||||
# Run four tests in parallel on some Xdummy servers
|
||||
./complete-run.pl -d :1,:2,:3,:4
|
||||
|
||||
Note that it is not necessary to specify this anymore. If omitted,
|
||||
complete-run.pl will start (num_cores * 2) Xdummy instances.
|
||||
|
||||
=item B<--valgrind>
|
||||
|
||||
Runs i3 under valgrind to find memory problems. The output will be available in
|
||||
C<latest/valgrind.log>.
|
||||
|
||||
=item B<--coverage-testing>
|
||||
|
||||
Exits i3 cleanly (instead of kill -9) to make coverage testing work properly.
|
||||
|
||||
=item B<--parallel>
|
||||
|
||||
Number of Xdummy instances to start (if you don’t want to start num_cores * 2
|
||||
instances for some reason).
|
||||
|
||||
# Run all tests on a single Xdummy instance
