I'm using simple-git in my script like this:
import simpleGit from 'simple-git'
const git = simpleGit()
const foo = async (): Promise<void> => {
const tags: string = await git.tag({
'--list': null,
'--format': '%(objectname:short)'
})
}
In my tests I need to mock out the git calls, which I'm doing this way:
jest.mock('simple-git', () => ({
tag: () => jest.fn()
}))
But this is failing. I guess, I have to take care of const git = simpleGit()

If simple-git is installed via node_module (which I assume it is) you only need to create a directory called __mocks__ at the root of your project anything placed there is automatically mocked in your case you need to create a file called simple-git.js
.
├── __mocks__
│ └── simple-git.js
├── node_modules
