How to use `test-matrix` with mxdev

[petschki]

I'm wondering, how we could use the test-matrix feature if I enable use_mxdev ... someone has a pointer?

I do not get the problem, but am willing to help.

I'll try to explain: since plone/meta#2.x there is the new test_matrix option, to configure which python/plone version you want in tests... the tox envs are then setup with different constraint files (see for example https://github.com/plone/plone.tiles/blob/master/tox.ini#L111-L113)

I have another repo, where I switched to use_mxdev = true but then plone/meta removes the toxenvs and "only" adds the -c constraints-mxdev.txt here https://github.com/plone/plone.app.tiles/pull/62/files#diff-ef2cef9f88b4fe09ca3082140e67f5ad34fb65fb6e228f119d3812261ae51449L111-R112 ... so I'm not sure, but plone/meta maybe could use the test-matrix feature and setup different -c constraints-mxdev-plone6[0,1,2].txt configs ?
