It seems that some time ago we stopped Travis reporting various test errors,
The problem is that the various test operations occur in groups of commands joined by ";" and Travis only checks the final RC value. So by wrapping a test in cd-in and -out commands
( e.g.
"cd my/inner/dir; test; cd ../../..")we have masked any errors that the test raises !
So, this fixes that.
At present we are failing on both a doctest and the whatsnew-aggregation check.
Those need fixing separately.
So it will make sense to merge this with the "doctest" check failing
P.S.
I also changed the order of the test matrix, so it runs "TEST_TARGET=coding" first.
I think it makes sense to get the earliest possible warning of pep8/header failures, which is after all what this target was added for. Also to run "minimal" before "full" for the same reason.
This is particularly desirable since we restricted the number of cpus so that Travis is no longer starting all the targets at once.
