| # Webhook Integration Test testdata | ||
|
|
||
| This contains a tiny module used for testdata for the webhook integration | ||
| test. The directory should always be called testdata, so Go treats it | ||
| specially. | ||
|
|
||
| The `cronjob_types.go` file contains the input types, and is loosely based | ||
| on the CronJob tutorial from the [KubeBuilder | ||
| Book](https://book.kubebuilder.io/cronjob-tutorial/cronjob-tutorial.html), but with added | ||
| methods to test webhook generation behavior. | ||
|
|
||
| If you add a new marker, re-generate the golden output file, | ||
| `manifests.yaml`, with | ||
|
|
||
| ```bash | ||
| go generate | ||
| ``` | ||
|
|
||
| Make sure you review the diff to ensure that it only contains the desired | ||
| changes! | ||
|
|
||
| If you didn't add a new marker and this output changes, make sure you have | ||
| a good explanation for why generated output needs to change! |
