fix 1.0.3

Examples

Here’s a basic example with setup but no teardown:

from fix import with_fixture

def setup_only(context):

    def setup():
        """Add something to the context."""
        assert context == {}
        context.squee = "kapow"

    return setup

@with_fixture(setup_only)
def case(context):
    assert context == {"squee": "kapow"}

… and here’s a rather more involved one that creates some temporary files to work with, then deletes them during teardown:

import os
import shutil
import tempfile

from fix import with_fixture

def external(context, files=3):

    def setup():
        context.temp_dir = tempfile.mkdtemp()
        context.filenames = ["file_%03d" % i for i in range(files)]
        for filename in context.filenames:
            with open(os.path.join(context.temp_dir, filename), "w") as f:
                f.write("This is the file %r.\n" % filename)

    def teardown():
        shutil.rmtree(context.temp_dir)

    return setup, teardown

@with_fixture(external, files=5)
def check_files(context):
    present = 0
    absent = 0
    for filename in context.filenames:
        if os.path.exists(os.path.join(context.temp_dir, filename)):
            present += 1
        else:
            absent += 1
    return context.temp_dir, present, absent

temp_dir, present, absent = check_files()
assert not os.path.exists(temp_dir)
assert present == 5
assert absent == 0

Installation

This should do the trick:

pip install fix
