test-utils: Typescript interface error RouterLink.d.ts

I have installed a VueJS 3 app and upgraded test-utils to the latest alpha. An attempt to serve the app locally returns this error:

node_modules/@vue/test-utils/dist/components/RouterLinkStub.d.ts:5:12 - error TS2707: Generic type 'ComponentOptionsBase<Props, RawBindings, D, C, M, Mixin, Extends, E, EE>' requires between 8 and 9 type arguments.

5 } & {}>) & import("vue").ComponentOptionsBase<Readonly<{
             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
6     to: any;
  ~~~~~~~~~~~~
7 } & {}>, unknown, unknown, {}, {}, Record<string, any>, string> & {
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It seems the interface ComponentOptionsBase is incorrectly specified or RouterLink.d.ts has the wrong number of arguments.

Is this expected behaviour or is this an issue? Is there a workaround?

See this file: https://unpkg.com/browse/@vue/test-utils@2.0.0-alpha.8/dist/components/RouterLinkStub.d.ts

If it’s correctly built from vue >= 3.0.0-beta.15, there should be something like ComponentOptionsMixin in it.

@lmiller1990 I think we should be able to fix the first issue on VTU side. For the second one, I spent some time debugging it and came with this workaround, but I was hoping to discuss it with @sodatea . This might be a good occasion to have his opinion on the matter 🙂 (cc @sodatea )
