Hi,

first impression comments below. I know you want
to avoid "one solution fits all", but I'm listing
some RFEs that I think are common.

- "installation of the system is left out"
Agreed, there are many provisioning solutions out there.

- replacing runltp + ltp-pan
What I'm missing is the local use-case we have now. Something
like backend:local, that will run the test on local system
and produce same format of results. ssh into localhost
adds complexity - some test wrapper might not know the
password for system it has been spawned on.

The way we coped with (fatal) issues is pre-processing
runtest files based on kernel version, package versions,
architecture, etc.

IMO backend:local (and ssh) might be closest to what people do now.

- RFE: filter tests
have ability to run only some tests based on some filter
which is very common question I get about runltp

- RFE: skip build/installation
for some cross-compiling users
  
- "All backends needs to be able to reach internet"
Why is this needed?

Regards,
Jan
