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 minukube:

Start by setting up a minikube instance to run the tests on:

# minikube profile launcher-tests
# minikube start

Run the tests:

make integration-tests

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

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

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

curl -Ls $(minikube service service --url) | sh -s -- --token=${WEAVE_CLOUD_TOKEN}
