This directory contains tests and testing docs for KFServing:

• Unit tests currently reside in the codebase alongside the code they test
• End-to-end tests:
  • They are in /test/e2e

kfserving-controller-manager has a few integration tests which requires mock apiserver and etcd, they get installed along with kubebuilder.

To run all unit tests:

make test

To run the e2e tests, you need to have a running environment that meets the e2e test environment requirements.

First have kfserving installed in a cluster.

To setup from local code, do:

1. ./hack/quick_install.sh
2. make undeploy
3. make deploy-dev

Install pytest and test deps:

pip3 install pytest==6.0.2 pytest-xdist pytest-rerunfailures
pip3 install --upgrade pytest-tornasync
pip3 install urllib3==1.24.2
pip3 install --upgrade setuptools

Go to python/kfserving and install kfserving deps

pip3 install -r requirements.txt
python3 setup.py install --force --user

Then go to test/e2e.

Run kubectl create namespace kfserving-ci-e2e-test

For KIND/minikube:

• Run export KFSERVING_INGRESS_HOST_PORT=localhost:8080
• In a different window run kubectl port-forward -n istio-system svc/istio-ingressgateway 8080:80
• Note that not all tests will pass as the pytorch test requires gpu. These will show as pending pods at the end.

Run pytest > testresults.txt

Tests may not clean up. To re-run, first do kubectl delete namespace kfserving-ci-e2e-test, recreate namespace and run again.

Optionally for more detailed info, in another window do kubectl get pod -n kfserving-ci-e2e-test -w > podwatch.txt
