Thank you.

I read the "test" issues on JIRA.  Some refer to mock frameworks.  I was
wondering if randomwalk was also such a test framework.  I haven't read the
code in the links above yet.  If randomwalk is indeed a test framework, is
there a link where I can read more about it?  I haven't done a web search
on randomwalk yet.

Randomwalk is one of our test frameworks. I don't know if it's a common testing framework in general, but we have a 'from scratch' implementation we use, which can be found in the test package under the server module. We don't really have documentation for it, but I like to think it's really simple. It just reads the XML file and loads appropriate nodes which are implemented for the tests, and then randomly selects a weighted edge to transition to a different node.

Hope that helps.
John

I would consider the randomwalk (and other tests in that suite) just an acceptance test suite. I think it is awesome that we have it as it is great for _really_ making sure the system is solid.

However, frameworks are more about providing a platform which is then built on by others to enable functionality (kinda like a library). Frameworks provide a way to think about problems and then some tools to enable you to solve them. So a mocking framework gives you a way to think about solving the problem of effectively unit testing and gives you mocks to help enable to solve the problem of unit testing.

Just a nitpick, but the terminology can be important especially when things (like the testing) are in flux.

Is pssh on your path or aliased? You should be able to do a straight pssh from your shell. If not, then that's the problem at hand, since the script expects it on your PATH or to have it aliased properly.
John

Pssh is called parallel-ssh on ubuntu.  You can fix it by using the
following script as "pssh"  early in your path.  I put mine in $HOME/bin

#! /bin/sh
exec parallel-ssh "$@"

Do we want to change the script to accommodate for the platforms?

At least this should go in the documentation (not having looked at them to see if it is already there :)
