# Regression test: Raspberry Pi / laptop SSH discovery uses rustscan, never
|
|
# nmap (nonfree NPSL licence; the pacman wrapper refuses to install it).
|
|
#
|
|
# Runs the real discover/ensure_dependencies functions with stubbed
|
|
# ip/getent/sshpass/rustscan/nmap/pacman on PATH and asserts:
|
|
# - rustscan is called as `-a <net> -p 22 -g` and nmap is never executed
|
|
# - our own IP is excluded and the Pi (answering the hostname probe) is found
|
|
# - ensure_dependencies asks for rustscan, not nmap
|
|
# - no script in the set still invokes nmap
