Problematic plugin testing due to types

[okineadev]

Describe the bug

I'm currently working on the vitepress-plugin-llms plugin for VitePress, and to make testing easier, I added tests from the very beginning

And that's great, it's thousands of times faster than running bun run docs:build every time and manually checking everything

But here's the problem - in order to avoid errors in the tests, I constantly have to add // @ts-ignore above each plugin hook, here's an example:

plugin = llmstxt({ generateLLMsFullTxt: false, generateLLMsTxt: false })
// @ts-ignore
plugin.configResolved(mockConfig)
await Promise.all([
	// @ts-ignore
	plugin.transform(0, 'docs/test.md'),
	// @ts-ignore
	plugin.transform(0, 'docs/test/test.md'),
	// @ts-ignore
	plugin.transform(0, 'docs/guide/index.md'),
])
// @ts-ignore
await plugin.generateBundle()

And if I remove // @ts-ignore, then there will be errors like this everywhere:

Cannot invoke an object which is possibly 'undefined'.ts(2722)
This expression is not callable.
  Not all constituents of type 'ObjectHook<(this: TransformPluginContext, code: string, id: string, options?: { ssr?: boolean | undefined; } | undefined) => TransformResult | Promise<...>>' are callable.

It looks scary, doesn't it?

So I want to know how to make sure that there are no such errors in the tests, and can you advise me a Plugin type that will not give such errors when calling hooks and I would not have to add // @ts-ignore ?

Thanks in advance
