Kiali Integration Tests

Project Structure

  • tests/integration/: Root directory
    • tests: Tests
    • utils: Support utilities

Environment Setup

  • System dependencies that will need to be available

    • oc or kubectl
    • go
    • make
    • npm
    • yarn

  • It is expected that the following have already been deployed in a OpenShift or non-OpenShift cluster:

    • Istio (Deployed into istio-system namespace, also including Grafana, Prometheus, etc.)
    • Kiali (Deployed into istio-system namespace)
    • Bookinfo (with traffic generated to Bookinfo)

Useful hack scripts

You can use the following to help setup the environment if you do not already have one as detailed above.

  • hack/istio/install-istio-via-istioctl.sh

    • Installs the latest Istio release into istio-system namespace along with the Prometheus, Grafana, and Jaeger addons.

  • hack/istio/install-bookinfo-demo.sh

    • Installs the Bookinfo demo that is found in the Istio release that was installed via the hack/istio/install-istio-via-istioctl.sh hack script.
    • Pass in -tg to also install a traffic generator that will send messages periodically into the Bookinfo demo.
    • If using Minikube and the -tg option, make sure you pass in the Minikube profile name via -mp if the profile name is not minikube.

  • Make targets to install Kiali

    • You must have a development environment on your local machine. Clone the kiali/kiali, kiali/kiali-operator, and kiali/helm-chart repos per the dev docs.
    • If using OpenShift:
      • You must first be logged into the OpenShift cluster via oc login.
      • Log into the internal image registry via podman or docker. Run make cluster-status and look in the output for the login command to use.
      • Run make build build-ui cluster-push operator-create kiali-create
    • If using Minikube:
      • Run make -e CLUSTER_TYPE=minikube build build-ui cluster-push operator-create kiali-create
      • If your Minikube profile name is not the default minikube, you must also pass in the env var -e MINIKUBE_PROFILE="<your profile name>"

  • hack/run-integration-tests.sh

    • Does all the work for you by setting up a local kind cluster and running the test suite against that enviornment.

Run the integration tests

OpenShift

# Clone this repository if you do not yet have it
$ git clone https://github.com/kiali/kiali.git

# Login to Openshift Cluster - you must specify your OpenShift cluster information and credentials
$ oc login https://<openshift>:<port> --username=<username> --password=<password> --insecure-skip-tls-verify=true

# Run all tests using the Kiali Route and authenticated as the user that is logged in
$ make test-integration -e URL="https://$(oc get route -n istio-system kiali -o 'jsonpath={.spec.host}')" -e TOKEN="$(oc whoami -t)"

# test results are stored in the "tests/integration/junit-rest-report.xml" file

Minikube

# Clone this repository if you do not yet have it
$ git clone https://github.com/kiali/kiali.git

# In a separate console, run a port-forward proxy to the Kiali running in the cluster
$ kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app.kubernetes.io/name=kiali -o name) 20001:20001

# Run all tests using the Kiali port-forward proxy and authenticated as the Kiali service account
$ make test-integration -e CLIENT_EXE="kubectl" -e URL="http://localhost:20001/kiali" -e TOKEN="$(kubectl get -n istio-system $(kubectl get secret -n istio-system -o name | grep 'kiali.*-token' | head -n 1) -o jsonpath={.data.token} | base64 -d)"

# test results are stored in the "tests/integration/junit-rest-report.xml" file

  • The Bookinfo namespace is cleaned of pre-existing Circuit Breakers and Virtual Services. Therefore, ignore any errors during the clean-up that follow the message: "Cleanning up (Note: ignore messages: "Error from server..."
