A currently experimental attempt at an RSpec-esque BDD testing framework for Python.
Basically we’re aiming for syntax along these lines:
from rgf import describe, it with describe("That Thing"): @it("test desc") def spec(context): # test code here assert stuff()
x_spec.py files go in a directory structure under, by convention, spec/ in the root of your project and are run using:
The specifics of the syntax are currently wrong, being borrowed directly from RSpec. Suggestions warmly received.
(Current front-runners are subject and context in place of describe, keeping it for the spec decorator.)
Because the spec functions are just functions, not methods, and are hoovered up by the @it decorator they’re effectively anonymous and can all have the same name for ease of thinking:
with subject('This Class'): @it('can calculate X') def s(world): pass @it('can account for Y') def s(world): pass
The aim is for something pythonic, with nested context and good spec names being the primary focus: minimum magic, minimum fuss.
- bump to update the Changelog, which I had neglected to do for 0.2.0 (sorry)
- Python 3 support, courtesy of Marc Abramowitz
- create rgf and rgf-x.y scripts using distribute
- ExampleGroups can be nested using with describe():
- Anonymous module collection of specs using randomly-generated module names. (fixes problems with imports of specs related to polluting sys.modules)
