nose-detecthttp

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

======================================================================

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 --vcr-ignore-host=www.example.com app/
test_one (app.tests.ExternalTestCase) ... ok
test_two (app.tests.ExternalTestCase) ... ok

----------------------------------------------------------------------

OK

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