| -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1 The requests' area | The main area of your load test. Double-click a request to manage its headers, parameters and assertions. [Learn More](https://docs.loadmill.com/api-testing/test-suite-editor/request-editor) |
| 2. Tested Domains    | Manage domains/hosts tested by the load test. See your domain in red? Check how to verify it [here](https://docs.loadmill.com/load-testing/setup/domain-verification).                         |
| 3. DRY RUN           | Run your load test as [a single iteration](https://docs.loadmill.com/load-testing/getting-started#running-a-trial-test).                                                                       |
| RUN TEST             | Run your load test [at scale](https://docs.loadmill.com/getting-started/getting-started-1#running-a-load-test-at-scale).                                                                       |
| 4. Advanced Settings | Configure Iterations, E-mail notifications, enable Cookies, [Import CSV](/performance-testing/creating-a-parameterized-load-test.md) and more.                                                 |
| 5. Replace Parameter | Easily replace the parameter you wish so all of the flow's requests will be affected.                                                                                                          |
| Extract Parameter    | [Extract a value to a parameter](/test-editor-reference/flows/flow-controls.md#extract-parameter) from all across the test requests.                                                           |
