Running the integration tests locally

Launcher has quite few components and we provide a way to test the full end to end flow in a local cluster:

To run the tests:

make
make integration-tests WEAVE_CLOUD_TOKEN=<YOUR_TEST_INSTANCE_ON_FRONTEND.DEV.WEAVE.WORKS>

This script will first ensure the dependencies are built and then run:

• reset-local-cluster.sh
• setup-local-cluster.sh
• run.sh

One can also use the local launcher service to provision a cluster:

LOCAL_IP=$(kubectl --context=kind-launcher-tests get nodes -o=jsonpath='{range .items[*]}{.status.addresses[?(@.type=="InternalIP")].address}{end}')
curl -Ls $LOCAL_IP:30080 | sh -s -- --token=${WEAVE_CLOUD_TOKEN}
