Package: tox-factor
tox-factorWhat is tox-factor?tox-factor enables running a subset of tox test envs, based on factor matching.Okay, but what does thatactuallymean?Take the following tox config:[tox]envlist=py{35,36,37}-django{20,21,22}-{redis,memcached}The above defines 18 test envs, based on three factor groups - the python
version, the django version, and a caching backend. While the above is powerful,
tox does not provide a way to run builds based on a subset of those factors.
For example, the call to run all Python 3.7 builds would be:$tox-epy37-django20-redis,py37-django20-memcached,py37-django21-redis,py37-django21-memcached,py37-django22-redis,py37-django22-memcachedtox-factor functions similarly to the-e <env name>argument, except it runs
all envs that match the given factor. The sixpy37builds could be ran with:$tox-fpy37In addition to ease of use when running tox locally, this is useful for some CI
setups. For example, two common tox CI patterns are to either:Define a CI job for each tox test env. e.g.,tox -e py37-django20-redisDefine a CI job for a common environment that runs multiple test envs. e.g.,tox -e py37-django20-redis,py37-django20-memcached,...For the latter case, this plugin eases maintenance of CI, as it could be
shortened totox -f py37. Additionally, take the following update to the above
tox config:[tox]envlist=py{35,36,37}-django{20,21,22}-{redis,memcached}py{36,37,38}-django{30}-{redis,memcached}By using tox-factor, it wouldn't be necessary to update the Python 3.7 build, as
the newpy37-django30-*env would be matched automatically.Verifying the matched test envsIf you want to verify which test envs are actually ran, combine the factor
matching with the-lflag. This will display all test envs that match. e.g.,$tox-fpy37-l
py37-django20-redis
py37-django20-memcached
py37-django21-redis
py37-django21-memcached
py37-django22-redis
py37-django22-memcachedUsage detailsThe factor option accepts a comma-separated list (similar to the-eoption).$tox-fpy27,py37-l
py27-django111
py37-django21Alternatively, factors can be provided via theTOXFACTORenvironment variable:$TOXFACTOR=py27,py37tox-l
py27-django111
py37-django21Factors can also match non-generative env names. For example, given the
following tox config:[tox]envlist=py{35,36,37}-django20[testenv:list]Then the following would match:$tox-fpy37,lint-l
py37-django20
lintFactors are always superseded by a giventoxenv. For example, tox-factor would
noop in the following cases:$tox-fpy37-epy35-django21-l
py35-django21

$TOXENV=py35-django21tox-fpy37-l
py35-django21Factors do not support partial matching.tox -f py3would not matchpy37.
However, factors may match disparate dash-separated parts. Given the following:[tox]envlist=py{35,36,37}-django{20,21,22}-{redis,memcached}Thentox -f py37-rediswould match:py37-django20-redis
py37-django21-redis
