Thanks doug, I updated my 2 requests using toxgen (and submitted pull to toxgen for some minor adjustments).

https://review.openstack.org/#/c/65123 should solve the immediate problem (uses toxgen to make a new tox.ini with the different variations to check).

https://review.openstack.org/#/c/65135 will add automatic execution of the venv 'matrix' (different sa versions, eventlet, not eventlet…), hopefully that is fine with the infra folks (it does add a lot of new testing venvs, I guess that’s ok?).

Once the rest of taskflow core checks out a few reviews then should be ok to release 0.1.2 and all will be merry.

It is.  See pecan for an example:


toxgen is another tool that might be useful for setting up your tests. It tries to simplify creating a tox.ini with variations on different axes (like changing versions of sqlalchemy but keeping all the other dependencies the same).

There's source for toxgen at https://bitbucket.org/cdevienne/toxgen and there's a copy in the WSME tree (I don't know if they're the same) with a tox-tmpl.ini file to serve as an example.


And thanks to Ryan Petrello for setting that system up!
