Description Tom Henderson 2013-05-01 09:34:51 EDT

When the test order is perturbed by running them like this:

./waf --run "test-runner --test-type=unit"

a few tests fail:

mobility-trace, devices-wifi, ipv6-raw, and ipv6-address-helper

this is most likely because there is usage of random variables in these tests that are not fixed to particular streams.  Another possible reason is that the seed and/or run number need to be fixed.

This changeset shows the nature of the fixes that are likely needed:

Comment 1 Tom Henderson 2013-05-01 09:37:58 EDT

before closing this bug, I'd like to see one of the jenkins scripts extended to run the tests this way, as well as the deep valgrind runs.
