### Reproducing failures in flaky tests
You can run a test repeatedly until it fails. This is useful when debugging
flaky tests. In order to do so, you need to set the following environment
variable:
```sh
$ export GINKGO_UNTIL_IT_FAILS=true
```
After setting the environment variable, you can run the tests as before. The e2e
script adds `--untilItFails=true` to ginkgo args if the environment variable is
set. The flags asks ginkgo to run the test repeatedly until it fails.
### Federation e2e tests
By default, `e2e.go` provisions a single Kubernetes cluster, and any `Feature:Federation` ginkgo tests will be skipped.
