[oe] protobuf: question about ptest

[Oleksandr Terentiev]

Hi,

Recently I tried to launch ptests for protobuf packet and it looks like 
tests themselves need interaction with a user.
Here is an output when I run /usr/lib/protobuf/ptest/run-ptest

> root at qemux86:~# /usr/lib64/protobuf/ptest/run-ptest
> Generating new test file using add_person_cpp...

I looked at run-ptest script
http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-devtools/protobuf/protobuf/run-ptest
And it seems doesn't implement user interaction as protobuf tests require.
So what is the best way to automate those tests?

Thanks,
Alex Terentiev
