How can I rewrite SpyInstance using MockInstance?

[rinarakaki]

The doc says:

SpyInstance is removed in favor of MockInstance

but MockInstance is not a drop-in replacement of SpyInstance. How can I migrate correctly?

On the same page it says how all mock functions and types are also changed with examples: https://vitest.dev/guide/migration#simplified-generic-types-of-mock-functions-e-g-vi-fn-t-mock-t

This page says nothing about SpyInstance.

@sheremet-va Your link includes an anchor that doesn't seem to exist on that page. I also cannot find any instance of the phrase "simplified generic" on the page.

@acolchagoff On the page linked, I took inspiration from the Types section (https://vitest.dev/guide/migration.html#types) and made the following code change successfully:

Before:

let sortColumnSpy: jest.SpyInstance;
sortColumnSpy = vi.spyOn(component.sortColumnName, 'emit');

After:

import { Mock } from 'vitest';

let sortColumnSpy: Mock;
sortColumnSpy = vi.spyOn(component.sortColumnName, 'emit');
