calve_machine

Factories for plain old Python objects.

Usage:

from calve_machine import inseminate, pregnant

@inseminate
def programmer(p):
    p.name = 'Sheldon Cooper, Ph.D.'
    p.age = 29
    p.languages = ['eiffel', 'io', 'erlang']

prog = pregnant.calve('programmer')
prog.name |should| equal_to('Sheldon Cooper, Ph.D.')
prog.age |should| be(29)
prog.languages |should| equal_to(['eiffel', 'io', 'erlang'])

Factories can inherit from other(s):

@inseminate
def programmer(p):
    p.name = 'Sheldon Cooper, Ph.D.'
    p.age = 29
    p.languages = ['eiffel', 'io', 'erlang']

@inseminate(sperm_from='programmer')
def python_programmer(p):
    p.languages = ['python']
    p.foo = 'spam'

prog = pregnant.calve('python_programmer')
prog.name |should| equal_to('Sheldon Cooper, Ph.D.')
prog.age |should| be(29)
prog.languages |should| equal_to(['python'])
prog.foo |should| equal_to('spam')

@inseminate(sperm_from='python_programmer')
def zope_programmer(p):
    p.languages = ['zcml']
    p.age = 30

prog = pregnant.calve('zope_programmer')
prog.name |should| equal_to('Sheldon Cooper, Ph.D.')
prog.age |should| be(30)
prog.languages |should| equal_to(['zcml'])
prog.foo |should| equal_to('spam')

How to install

The project is at a very early stage, there's no PyPi release.

How to run tests

Just run:

make test

for install all test dependencies (Should-DSL and Specloud, at the moment) and run the tests. calve_machine itself has no dependencies.
