 The following inputs can be used as `step.with` key:
 
-| Name | Type | Required | Description 
-| --- | --- | --- | --- |
-| `path` | string | `true` | Glob pattern to select one or multiple test scripts to run. <br/> e.g. `./tests/api*.js` <br/> One can also supply multiple patterns by separating them with new line.<br/><code>path: \|<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;./tests/api*.js<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;./tests/app*.js</code>
-| `cloud-run-locally` | boolean | `false` | If `true`, the tests are executed locally and the results are uploaded to Grafana Cloud k6
-| `parallel` | boolean | `false` | If `true` and multiple tests are executed, all them run in parallel. 
-| `fail-fast` | boolean | `false` | If `true`, the whole pipeline fails as soon as the first test fails 
-| `flags` | string | `false` | Additional flags to be passed on to the `k6 run` command.<br/>e.g. `--vus 10 --duration 20s`
