Re: what if I wanted to write some tests...

[Vara Prasad <prasadav at us dot ibm dot com>]

Looking at this experience of Brad i am thinking (a loud) may be it is 
time for us to do regular integration testing .

A simple system using the test bed to do a periodic build on UP/SMP 
x86/x86_64 platforms for now,  from the CVS and then probably run few 
basic tests to see if they pass. Once these two steps are passed, create 
a tar ball of the extracted code and have an automatic link to that tar 
ball on the website.

This brings up following issues that we have to address

1) How often we check out the code and do the build?
My guess, considering we are not doing way too many changes at this time 
probably once a week may be on Tuesday so that before Thursday we will 
have issues observed to discuss on the call if need be. Of course if  
someone checks a major change it would be nice to initiate this process 
on demand as well.

2) Where is the test bed?
I thought Will is looking into this using the RH test grid (Will correct 
me if i am wrong). If this is correct is that the right test bed to do 
this kind of build and sanity test? If this is not which other place we 
can use? The other one that comes to my mind is the test suit Rusty 
mentioned that he is planning to put together. Is there a test bed in 
Intel that can pull the code and push the tar ball after successful 
tests? Will there be any firewall issues in accessing and pushing the 
tar ball to the website/CVS?

3) How about other architectures mainly PPC 64 and IA 64?

Regarding PPC 64 i am thinking Ananth has access to PPC 64 machines that 
he can access without firewall issues, so that might work . I don't know 
if there are any IA64 machines available within the RH firewall if not 
how Intel can can help here.

4) Do we have a sanity test suit for us to declare a good build?

For now i am thinking the examples in the CVS could be a good start. If 
we have the kprobes tests Rusty/Anil was putting together that would be 
good too.

Any other issues i am missing?

Please let me know your thoughts on this proposal.

Thanks,
Vara Prasad
