mamba: the definitive test runner for Python
mamba is the definitive test runner for Python. Born under the banner of behavior-driven development.
Install
I recommend to use pipenv for managing your dependencies, thus you can install mamba like any other Python package.
By example:
$ pipenv install mamba
But you also can use pip:
$ pip install mamba
Getting Started
Write a very simple example that describes your code behaviour:
# tennis_spec.py
from mamba import description, context, it
from expects import expect, equal
with description('Tennis') as self:
with it('starts with 0 - 0 score'):
rafa_nadal = "Rafa Nadal"
roger_federer = "Roger Federer"
game = Game(rafa_nadal, roger_federer)
expect(game.score()).to(equal((0, 0)))
Run the example, and don't forget to watch it fail!
$ pipenv run mamba tennis_spec.py
F
1 examples failed of 1 ran in 0.0023 seconds
Failures:
1) Tennis it starts with 0 - 0 score
Failure/Error: tennis_spec.py game = Game(rafa_nadal, roger_federer)
NameError: global name 'Game' is not defined
File "tennis_spec.py", line 8, in 00000001__it starts with 0 - 0 score--
game = Game(rafa_nadal, roger_federer)
Now write as little code for making it pass.
# tennis_spec.py
from mamba import description, context, it
from expects import expect, equal
import tennis
with description('Tennis') as self:
with it('starts with 0 - 0 score'):
rafa_nadal = "Rafa Nadal"
roger_federer = "Roger Federer"
game = tennis.Game(rafa_nadal, roger_federer)
expect(game.score()).to(equal((0, 0)))
# tennis.py
class Game(object):
def __init__(self, player1, player2):
pass
def score(self):
return (0, 0)
Run the spec file and enjoy that all tests are green!
$ pipenv run mamba tennis_spec.py
.
1 examples ran in 0.0022 seconds
Settings
Mamba provides a way to configuration using spec/spec_helper.py or specs/spec_helper.py
This module function is read after parsing arguments so configure function overrides settings
A sample config file :
def configure(settings):
# settings.slow_test_threshold = 0.075
# settings.enable_code_coverage = False
# settings.code_coverage_file = '.coverage'
settings.format = 'documentation'
# settings.no_color = False
# settings.tags = None
