Python library Python test fixtures test fixtures

fix Description

fix is a simple Python library to assist with the creation of fixtures for test functions, methods etc. It provides one decorator, with_fixture, which allows you to attach setup() and teardown() functions to the decorated callable, and access information defined in the fixture from within the test function.fix was written for use with nose, but doesn't depend on it, and may also prove useful with other test frameworks.ExamplesHere's a basic example with setup but no teardown:from fix import with_fixturedef 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 osimport shutilimport tempfilefrom fix import with_fixturedef external(context, files=3): def setup(): context.temp_dir = tempfile.mkdtemp() context.filenames = 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, absenttemp_dir, present, absent = check_files()assert not os.path.exists(temp_dir)assert present == 5assert absent == 0InstallationThis should do the trick:pip install fixProduct's homepage
