Not sure if complete test coverage is possible. There are more that

IMHO versioning make sence only for 3rd party scripts/models. If we will
version Processing algs, we quickly end up with a mess, as each commit
which fixes alg will produce new alg version inside same Processing version.
So, for example, inside QGIS 2.16 we will have Processing 2.16, some algs
just with 2.16.0 version and multiple versions of other algorithms, e.g 2.16.0,
2.16.1, 2.16.2 and so on.

Documentation is another importand topic. There is some movement in this
direction, but again unfortunately we can not cover all Processing algs with
documentation. Reusing existing documentaion (e.g GDAL, SAGA, GRASS)
can help, but as many Processing algs implement only subset of options or
even split one tool into multiple... existing documentation does not match
