A nose plugin to detect tests making http calls.

Project Description

A nose plugin that can detect tests making external http calls. Example output:

$ nosetests -v --with-detecthttp myapp/
test_that_makes_request ... ok
test_with_no_request ... ok

FAIL: Tests made external http calls
- myapp.tests.AppTest:


Ran 2 tests in 0.001s

FAILED (failures=1)

Sometimes, you want to ignore hosts besides localhost. For example, you might be running tests in a containerized environment where dynamodb has the hostname dynamodb and mysql has the hostname mysql. To ignore these hosts, the --vcr-ignore-host option:

nosetests -v --with-detecthttp app/
test_one (app.tests.ExternalTestCase) ... ok
test_two (app.tests.ExternalTestCase) ... ok

Ran 2 tests in 0.042s


Under the hood, this wraps every test in a separate cassette. Since’s hooks are in the stdlib, this approach won’t detect requests made with clients like PycURL.
