+# Testing a draft managed script
+
+When developing a new [managed script](https://github.com/openshift/managed-scripts), you often want to run your draft before it is merged.
+
+Previously this was done with `ocm backplane testJob create/get/logs`, which required the backplane API to build and run a test job. Those subcommands are now **deprecated**.
+
+The recommended way is `ocm backplane testJob render`, which generates the Kubernetes YAML (ServiceAccount, RBAC and Pod) for your script **locally** — no backplane API call is made. You then apply it directly on a non-production cluster where you have cluster-admin access.
+
+
+## Prerequisite
+You have a non-production ROSA cluster that you own or control, with cluster-admin permissions to create resources in it. For example, your own cluster with direct cluster-admin access via IDP, or a staging cluster where you have backplane elevation permissions.
+
+## Example
+
+Assuming your draft script lives in a directory that contains a `metadata.yaml` and the script itself (the same layout used in the [managed-scripts](https://github.com/openshift/managed-scripts) repo):
+
+```bash
+# 1. Log in to a non-production cluster with cluster-admin access
+oc login <cluster-api-url>
+
+# 2. Render the YAML from your script directory
+cd scripts/SREP/example
+ocm backplane testJob render -p VAR1=val1 > test-job.yaml
+
+# 3. Review the generated YAML, then apply it
+oc apply -f test-job.yaml
+
+# 4. Watch the job and inspect its logs with standard oc commands
+oc -n openshift-backplane-managed-scripts get pods
+oc -n openshift-backplane-managed-scripts logs <pod-name>
+
+# 5. Clean up after testing
+oc delete -f test-job.yaml
+```
+
+## Useful flags
+
+| Flag | Description |
+| ---- | ----------- |
+| `-p, --params 'VAR1=val1'`        | Pass parameters to the script (repeatable, e.g. `-p 'VAR1=val1' -p VAR2=val2`). |
+| `-s, --source-dir <dir>`          | Directory of the script to render (defaults to the current directory).          |
+| `-i, --base-image-override <img>` | Container image used to run the script. Defaults to the latest managed-scripts image resolved from GitHub. |
+| `-o, --output <file>`             | Write the rendered YAML to a file instead of stdout.                            |
