Message:

Merge branch 'xry111/tester-nohack' into trunk

Use a fixed UID for "tester" user, instead of the tty owner's UID.

The problem using tty owner's UID is, when tty is owned by "root" the
UID of "tester" will be 0. This cause a namesis between "tester" and
root. And, the "tester" is introduced to run some tests which are not
expected to be ran as root. If "tester" has UID 0, it will have root
priviledge and the tests will fail again.

Bash tests require the user to own the tty. To satisify it, we use
Expect to spawn a new pseudoterminal to run Bash tests.
