We got an error when using vue-tsc --noEmit to compile our Vue project.

  The last overload gave the following error.
    .......... hidden errors - It's not important ...........
              Types of parameters 'ctx' and 'ctx' are incompatible.
                Type 'SetupContext<string[]>' is not assignable to type 'SetupContext<EmitsOptions>'.
                  Type 'EmitsOptions' is not assignable to type 'string[]'.
                    Type 'ObjectEmitsOptions' is missing the following properties from type 'string[]': length, pop, push, concat, and 28 more.

So I compared the @vue/test-utils/dist/mount.d.ts and @vue/runtime-core/dist/runtime-core.d.ts files, I see one of the overloads of the defineComponent methods with a different default type value.

export declare type DefineComponent<..., E extends EmitsOptions = Record<string, any>, ...> = ...;

export declare function defineComponent<Props, RawBindings = object>(setup: (props: Readonly<Props>, ctx: SetupContext) => RawBindings | RenderFunction): DefineComponent<Props, RawBindings>;

// The default type is defined as EmitsOptions, but other overloads and the definitions in @vue/test-utils is with Record<string, any>
export declare function defineComponent<..., E extends EmitsOptions = EmitsOptions, ...>(options: ...): DefineComponent<Props, RawBindings, D, C, M, Mixin, Extends, E, EE>;

export declare function defineComponent<..., E extends EmitsOptions = Record<string, any>, ...>(options: ...): DefineComponent<Readonly<{
    [key in PropNames]?: any;
}>, RawBindings, D, C, M, Mixin, Extends, E, EE>;

export declare function defineComponent<..., E extends EmitsOptions = Record<string, any>, ...>(options: ...): DefineComponent<PropsOptions, RawBindings, D, C, M, Mixin, Extends, E, EE>;

I think it would be a hidden issue. Since we are using shims definition for Vue so that it is difficult to find. For us, we temporarily use any as a workaround.

mount(CurrentTime as any)
