New TSQA and Testing transparency

[Susan Hinrichs]

I just wrote my first test to verify TS-3140 (the recent 5.2.1 
backport).  Once I got the environment going, writing the test was quite 
easy!

Now I'm looking at some tests for transparency (verifying TS-3073). I 
need be able to send a packet to example.com on port 80, have ATS 
transparently intercept, and transparently pass through the non-HTTP 
request and response.  I believe to accurately test this, I need three 
virtual networks.

I've done something similar using Linux namespaces via Linux 
Containers.  New network namespaces can easily bet set up via shell 
scripts and I'm sure python can issue those commands as well.
1.  Does new_tsqa already have a mechanism for setting up multiple 
virtual networks?
2.  If not, does anyone have problems with me pursuing a Linux 
Containers solution?  Do we have to run all the new_tsqa tests on 
non-Linux platforms as well?

Thanks,
Susan
