How type mocks with vitest?
问题
如何改进此处的类型定义？
英文:
I want to mock fs with vitest and I am successfully doing so, however I am using any to do so. Consider
import { promises as fs } from 'fs';vi.mock('fs')it('can mock', async () => {// Property 'mockResolvedValue' does not exist on type '{ ......fs.readdir.mockResolvedValue([])// ok but can we do better?(fs.readdir as any).mockResolvedValue([])})
How can I improve the typing here?

import { promises as fs } from 'fs';
vi.mock('fs')
it('can mock', async () => {
vi.mocked(fs.readdir).mockResolvedValue([])
})
英文:
As @jonrsharpe pointed to in the comment, we can use this syntax:
import { promises as fs } from 'fs';vi.mock('fs')it('can mock', async () => {vi.mocked(fs.readdir).mockResolvedValue([])})

我通过以下方式解决了这个问题：
import { vi } from 'vitest'import axios from 'axios';// 模拟库vi.mock('axios')// 模拟库方法const mockedAxios = vi.mocked(axios, true)
你可以在 vitest 文档中查看这个 https://vitest.dev/guide/mocking.html#mocking
英文:
I resolve this by follow way
import { vi } from 'vitest'import axios from 'axios';// mock libraryvi.mock('axios')// mock library methodsconst mockedAxios = vi.mocked(axios, true)
You can see this in vitest DOCS https://vitest.dev/guide/mocking.html#mocking

我一直在使用 typeof，我认为 @jonrsharpe 指向的是这个。类似于以下代码：
import * as fs from 'fs';const mockedFs = fs as Mocked<typeof fs>;mockedFs.readdir.mockResolvedValue([]);
英文:
I've been using typeof which is what I think @jonrsharpe was pointing you towards. Something like:
import * as fs from 'fs';const mockedFs = fs as Mocked<typeof fs>;mockedFs.readdir.mockResolvedValue([]);
