## Running e2e tests against the cluster

If you brought up an end-to-end test cluster using the steps above then you can
use the steps below to run K8s e2e tests. These steps are based on
[kubernetes-sigs/windows-testing](https://github.com/kubernetes-sigs/windows-testing).

*   Build the necessary test binaries. This must be done after every change to
    test code.

    ```bash
    make WHAT=test/e2e/e2e.test
