pytest-netscenario
A pytest plugin for netscenario: run a network scenario as a test and assert on loss, delay and throughput.
pip install pytest-netscenario # also installs netscenario, in exactly the same version
# test_video_call.py, next to video-call.yaml
def test_the_video_arrives_in_time(netscenario):
video = netscenario.run("video-call.yaml")["video"]
assert video.loss_ratio < 0.05
assert video.delay.p99 < 0.100 # seconds
The plugin gives the fixture netscenario (a runner that finds the scenario file next to the test), the marker netscenario(...) with the fixture netscenario_result, a guard that skips (or, on a CI, fails) when the machine cannot create network namespaces, and a section in the report with the numbers of each run. It needs Linux with the tools and rights that netscenario doctor checks (permissions).
A complete example with its scenario file and its output: examples/python-test. Documentation: docs/PYTEST.md. The status is pre-alpha.
