[not actively supported outside of internal Venmo usage]
A nose and pytest plugin that can detect tests making external http calls. With nose, it adds a single artificial failure with all the results:
$ nosetests -v --with-detecthttp example.py
test_that_makes_request (example.ExampleTests) ... ok
test_with_no_request (example.ExampleTests) ... ok
======================================================================
FAIL: Tests made external http calls
----------------------------------------------------------------------
- example.ExampleTests:
test_that_makes_request:
GET http://example.com/
----------------------------------------------------------------------
Ran 2 tests in 0.063s
FAILED (failures=1)
With pytest, failures are added to individual tests:
$ pytest --with-detecthttp example.py
...
item = <TestCaseFunction 'test_that_makes_request'>
def pytest_runtest_teardown(item):
# Note unmocked interactions collected during runtest_call.
# This is raised here so that pytest doesn't mark it as an internal error.
report = item.config._detecthttp_reports.pop(item.nodeid, None)
if item.config._detecthttp_enabled and report:
> raise report
E UnmockedRequestsDetected: detecthttp noticed the following requests during this test:
E GET http://example.com/
detecthttp/pytest.py:82: UnmockedRequestsDetected
...2 passed, 1 error in 0.35 seconds
Localhost is automatically ignored. To ignore other hosts, use the --vcr-ignore-host option, which takes a comma-delimited list:
$ nosetests -v --with-detecthttp --vcr-ignore-host=example.com example.py test_that_makes_request (example.ExampleTests) ... ok test_with_no_request (example.ExampleTests) ... ok ---------------------------------------------------------------------- Ran 2 tests in 0.110s 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.
