# Previewing a URL Redirect Test

You can preview any test directly in your browser with Shoplift's **Preview Mode**. Preview Mode can be used on draft, active, and ended tests.

### Using Preview Mode

On a given test draft or report, hover over your variant preview and select **View in Browser**. This opens Preview Mode in a new tab.

When using preview mode, you can experience your test as a website visitor would.

### Switching Between Variants

At the bottom of the preview window, you’ll see a toolbar that lets you switch between:

* **Original (A**) – your current experience
* **Variant (B)** – your test experience

<figure><img src="/files/uViRUPc6f61as4BbflUl" alt=""><figcaption></figcaption></figure>

You can navigate across your site while the preview is active to see how each page looks when assigned to the A or B variant.

### Exiting Preview Mode

To return to your live site, simply select Exit in the toolbar.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.shoplift.ai/test/url-testing/previewing-a-url-redirect-test.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
