The extended testsuite only works with uid=0. It contains of several
subdirectories named "test/TEST-??-*", which are run one by one.

To run the extended testsuite do the following:

$ make all  # Avoid the "sudo make" below building anything as root
$ cd test
$ sudo make clean check
...
make[1]: Entering directory `/mnt/data/harald/git/systemd/test/TEST-01-BASIC'
Making all in .
Making all in po
TEST: Basic systemd setup [OK]
make[1]: Leaving directory `/mnt/data/harald/git/systemd/test/TEST-01-BASIC'
...

If one of the tests fails, then $subdir/test.log contains the log file of
the test.

To debug a special testcase of the testsuite do:

$ make all
$ cd test/TEST-01-BASIC
$ sudo make clean setup run

QEMU
====

If you want to log in the testsuite virtual machine, you can specify
additional kernel command line parameter with $KERNEL_APPEND.

$ sudo make KERNEL_APPEND="systemd.unit=multi-user.target" clean setup run

you can even skip the "clean" and "setup" if you want to run the machine again.

$ sudo make KERNEL_APPEND="systemd.unit=multi-user.target" run

You can specify a different kernel and initramfs with $KERNEL_BIN and $INITRD.
(Fedora's or Debian's default kernel path and initramfs are used by default)

$ sudo make KERNEL_BIN=/boot/vmlinuz-foo INITRD=/boot/initramfs-bar clean check

A script will try to find your QEMU binary. If you want to specify a different
one you can use $QEMU_BIN.

$ sudo make QEMU_BIN=/path/to/qemu/qemu-kvm clean check
