-| `component`  | The newly created Svelte component. This is mostly useful for testing exported functions or cases where manipulating the DOM doesn't fit. Outside of said cases avoid using the component directly to build tests, instead of interacting with the rendered Svelte component, work with the DOM . |
-| `debug`      | Logs the `container` using [prettyDom](https://testing-library.com/docs/dom-testing-library/api-helpers#prettydom).                                                                                                                                                                               |

-| `rerender`   | Calls render again destroying the old component, and mounting the new component on the original `target` with any new options passed in.                                                                                                                                                          |

If you pass in `query` arguments than this will be those, otherwise all.                                                                                      |
