Previously, we were running the test suite for several combinations of MongoDB,
Python, and PyMongo:
- PyPy, MongoDB v2.6, PyMongo v3.x (which really means v3.6.1 at the moment)
- Python v2.7, MongoDB v2.6, PyMongo v3.x
- Python v3.5, MongoDB v2.6, PyMongo v3.x
- Python v3.6, MongoDB v2.6, PyMongo v3.x
- Python v2.7, MongoDB v3.0, PyMongo v3.5.0
- Python v3.6, MongoDB v3.0, PyMongo v3.5.0
- Python v3.5, MongoDB v3.2, PyMongo v3.x
- Python v3.6, MongoDB v3.2, PyMongo v3.x
- Python v3.6, MongoDB v3.4, PyMongo v3.x
- Python v3.6, MongoDB v3.6, PyMongo v3.x
There were a couple issues with this setup:
1. MongoDB v2.6 – v3.2 have reached their End of Life already (v2.6 almost 3
years ago!). See the "MongoDB Server" section on
https://www.mongodb.com/support-policy.
2. We were only testing two recent-ish PyMongo versions (v3.5.0 & v3.6.1).
We were not testing the oldest actively supported MongoDB/PyMongo/Python
setup.
This PR updates the test matrix so that these problems are solved. For the
sake of simplicity, it does not yet attempt to cover MongoDB v4.0:
- PyPy, MongoDB v3.4, PyMongo v3.x (aka v3.6.1 at the moment)
- Python v2.7, MongoDB v3.4, PyMongo v3.x
- Python v3.5, MongoDB v3.4, PyMongo v3.x
- Python v3.6, MongoDB v3.4, PyMongo v3.x
- Python v2.7, MongoDB v3.4, PyMongo v3.4
- Python v3.6, MongoDB v3.6, PyMongo v3.x
* added flake8 and flake8-import-order to travis for py27
* fixed a test that fails from time to time depending on an order of a dict
* flake8 tweaks for the entire codebase excluding tests
Remove nose/rednose from `setup_requires` and instead declare them in
`tests_require`. Also explicitly add `nose` and `rednose` to
dependencies list in tox.ini (to avoid breaking test runs).
`python setup.py nosetests` is the preferred way for running tests, and
this works, except that placing test deps (nose/rednose) in the
`setup_requires` also means that these dependencies are pulled in for
installs of mongoengine. These deps are not actually be required just
to run mongoengine, so setup.py should not force users to install these
dependencies.
This refactoring should not change any test run semantics.
