# System Flow Prerequisites

Before executing the System flow, ensure the following prerequisites are in place.

## Dummy User Account

- Tests are executed in the production environment; a dedicated dummy user is required for System testing.
- The user must have a Cavern home directory set up on every node where the operator will run the tests.
- The home directory is required to stage and manage test data during workflow execution.
- A user account `test_dummy_user` has been created with a lifetime of 12 months.
- If the account expires, contact `#team-src-neon` on Slack to request a renewal.
- ⚠️ Note: Use this dummy user only for System testing, not for production workflows.

### Required Groups

Add the dummy user to all of the following groups:

```
- data
- data/namespaces
- data/namespaces/chocolate
- data/namespaces/chocolate/owner
- monitoring
- monitoring/grafana
- prototyping-groups
- prototyping-groups/mini-src
- prototyping-groups/mini-src/platform-users
- services
- services/data-management-api
- services/data-management-api/roles
- services/data-management-api/roles/developer
- services/gateway-backend-api
- services/rucio
- services/rucio/roles
- services/rucio/roles/user
- services/site-capabilities-api
- services/site-capabilities-api/roles
- services/site-capabilities-api/roles/viewer
```

## Test Dataset

- The data file to be replicated between RSEs must be uploaded manually with a longer lifetime.
- This file serves as the source dataset in the workflow and will be staged under `/data/stage` on the source node.

### Steps to Upload Data to Rucio

1) Run the Rucio client container:

```bash
docker run -it --rm \
  -e RUCIO_CFG_CLIENT_ACCOUNT=accountname \
  -e RUCIO_CFG_CLIENT_OIDC_SCOPE="openid profile offline_access wlcg.groups storage.create:/" \
  -v path_to_file/file.txt \
  registry.gitlab.com/ska-telescope/src/src-dm/ska-src-dm-da-rucio-client:release-35.6.0
```

2) Upload the mounted file:

```bash
rucio upload --rse RSE_NAME --lifetime 3600 --scope testing --register-after-upload path_to_file/file.txt
```

Or generate and upload a random file:

```bash
export FILE=$(uuidgen)
echo "test" >> $FILE
rucio upload --rse CHSRC_XRD_PROD --lifetime 3600 --scope testing --register-after-upload $FILE
```
