btnamespace 1.1.0

Isolate state on the Braintree sandbox during testing.

Latest Version: 1.1.1

A Braintree namespace isolates state on the Braintree gateway:

import braintree
import btnamespace

with btnamespace.Namespace():
    customer = braintree.Customer.create({"id": "123"})
    assert customer.id == "123"
    braintree.Customer.find("123")  # success

braintree.Customer.find("123")  # NotFound exception

This is primarily useful during integration tests:

def setUp(self):
    self.namespace = btnamespace.Namespace()
    self.namespace.__enter__()

def test_some_sandbox_integration(self):
    #...

def tearDown(self):
    self.namespace.__exit__()

Compared to calling eg braintree.Customer.delete during tearDown, this has a number of advantages:

  • it’s faster, since no teardown is needed
  • it’s simpler, since it doesn’t require any bookkeeping
  • it’s robust, since tests can be written without any state assumptions

You can install it with $ pip install btnamespace.

What’s supported

  • Customer create, update, find, delete
  • CreditCard create, update, find, delete
  • Transaction create, find

All operations involving subresources - eg creating a CreditCard and Customer in one call - work as expected.

Adding support for other operations is easy; we just haven’t needed them yet. Contributions welcome!

How it Works

Under the hood, a Namespace globally patches the braintree client library.

During create operations, any provided ids are removed. This forces the gateway to respond with unique ids, which are later mapped back to the originally-provided ids. Here’s an example:

  • on a call to braintree.Customer.create({'id': '123', ...}), '123' is stored as a Customer id and the call becomes braintree.Customer.create({...}).
  • then, the server returns a unique id 'abcde' for the Customer. '123' is mapped to 'abcde', and the resulting Customer object’s id is set to '123'.
  • later, a call to braintree.Customer.find('123') becomes braintree.Customer.find('abcde').

Contributing

Inside your vitualenv:

$ cd btnamespace
$ pip install -e .
$ pip install -r requirements.txt

To run the tests, first add your sandbox credentials:

$ export BT_MERCHANT_ID=merchant-id
$ export BT_PUBLIC_KEY=public-id
$ export BT_PRIVATE_KEY=private-key

Then run $ python tests/test_integration.py.
