testing - How to make Travis CI to install Python dependencies declared in tests_require? -


i have python package setup.py. has regular dependencies declared in install_requires , development dependencies declared in tests_require, e.g. flake8.

i thought pip install -e . or running python setup.py test install development dependencies , they'll available. however, apparently they're not , struggle setup travis ci build right.

install:   - "pip install -e ." script:   - "python setup.py test"   - "flake8"

build configured above fail, because flake8 not found valid command. tried invoke flake8 inside of python setup.py test command (via subprocess), without success.

also hate fact flake8 can't made integral part of python setup.py test command, that's story.

i prefer keep of configuration in tox.ini , rely on install , run run. testing use pytest (the solution can modified use other testing frameworks easily).

following files used:

  • tox.ini: automates test
  • .travis.yml: instructions travis
  • setup.py: installation script install package test
  • test_requirements.txt: list of requirements testing

tox.ini

[tox] envlist = py{26,27,33,34}  [testenv] commands =     py.test -sv tests [] deps =     -rtest-requirements.txt

.travis.yml

sudo: false language: python python:     - 2.6     - 2.7     - 3.3     - 3.4 install:     - pip install tox-travis script:  - tox

test_requirements.txt

just ordinary requirements file whith ever need in there (e.g. flake8, pytest , other dependencies)

you may see sample @ https://github.com/vlcinsky/awslogs/tree/pbr-setup.py

the fact uses there pbr, coverage , coverall not relevant answer (it works or without pbr).

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
