[TestGrid](https://k8s-testgrid.appspot.com/istio-release) | A Kubernetes dashboard used for visualizing the status of the Prow jobs.

Test suites are defined for each toplevel directory (such as `pilot` and `telemetry`), so any tests added to these directories will automatically be run in CI.

If you need to add a new test suite, it can be added to the [job configuration](https://github.com/istio/test-infra/blob/master/prow/config/jobs/istio.yaml).
