Testing Page data

[jasonbhuang]

Hi guys I can't seem to find any clear info on how to unit test the Page data object, when I run vitest it starts with saying it is not able to render 'data' just following a basic example shown here

https://kit.svelte.dev/docs/load

/** @type {import('./$types').PageLoad} */
export function load({ params }) {
    return {
        post: {
            title: `Title  here`,
        }
    };
}

<script>
    /** @type {import('./$types').[PageData](https://kit.svelte.dev/docs/types#app-pagedata)} */
    export let data;
</script>

<h1>{data.post.title}</h1>

there is no way to get the data object to load property when running vitest, the application itself renders everything fine. Am I looking at this the wrong way what is the method used to test something straight forward like this?
