## Design principles

To avoid redundancy and confusion, the assertions in the criteria list must not be duplicated.

## Configuration

| Option | Type | Description |
|  --- | --- | --- |
| severity | string | Possible values: `off`, `warn`, `error`. Default `off`. |


An example configuration:


```yaml
rules:
  criteria-unique: error
```

## Examples

Given the following configuration:


```yaml
rules:
  criteria-unique: error
```

Example of a criteria list:


```yaml
successCriteria:
  - condition: $statusCode == 200
onSuccess:
  - name: 'onSuccessActionName'
    type: 'goto'
    stepId: 'buy-ticket'
    criteria:
      - condition: $response.body.open == true
onFailure:
  - name: 'onFailureActionName'
    type: 'goto'
    stepId: 'buy-ticket'
    criteria:
      - condition: $response.body.open == true
```
