Hi there,
I would like some help integrating TDD into my current projects.
My chosen TDD framework is unittest from the standard library. My
system details are: Linux Mint 17.1 64-bit, Python 3.4, bzr(for
version control).
My projects are structured like:
Project > develop > Project > Project > __main__.py
tests > __main__.py
I want to be able to execute my Project from a cwd of:
Project/develop/Project
as: Python3 -m Project
That currently works.
But executing my tests as: Python3 -m tests
requires that test_Project.py has this hack to import the Project module:
sys.path.append(os.path.join(os.path.dirname(__file__), '..'))
Yes, a bit ugly. Have you tried using nose? I have used a
similar project development tree and use nose to run the tests.
Here are a few sample command-lines (I'm on an opensuse-13.2 system
with Python 3.4 and nose for Python-3.4, which is called
'nosetests-3.4'):
nosetests-3.4 -- ./tests/
nosetests-3.4 --with-coverage -- ./tests/
nosetests-3.4 --with-coverage --cover-package=Project -- ./tests/
I like nose because it will discover any unittest and doctest
testing code under the specified files/directories.
do you consider that OK? Is there a better way?
I call it a hack because every testcase file will have to have
this line added to it in order to work.
Agreed, is a hack.
I am also using coverage.py and it is good but seems to be testing
the coverage of my tests, which is not desired, how can I stop
this behaviour. Or is it really OK.
That's precisely what coverage is supposed to do--that is it should
report on how much of the 'code under test' has been exercised by
the testing code. So, in fact, it's better than OK--it's the
primary point!
There are two good things about using coverage.
#1: You see how much more effort you should invest to get
substantial testing coverage of the code under test.
[Though, some code is easy to test and others very difficult.]
#2: You get a report of the lines in the code under test which are
NOT yet tested; handy!
Good luck,
-Martin
