Jest: import jest functions instead of having globals

[apflieger]

Feature request or documentation missing?
I'd like to do

import {test, expect} from 'jest'

The current behaviour with globals works but it's just not convenient because IDEs don't recognize the functions.

Here are some stackoverflow related to this:

@apflieger, I find that VSCode works fine if you install the Jest typings.

I couldn't find a way to make it work in IntelliJ

IDE compatibility is pretty good if you use typings from either flow or typescript

It's also not convenient because it breaks standardjs.
Of course, we can

• Add global ignore of jest it and other functions in standard config
• just go for import { it } from global

But I like to think that, if a linter complies, it's because it's a bad practise. And indeed everything in global is a bad practise, at the root of some evils.

Mocha supports it. Any plan to add it ?

We have some vague plans to support it, but nothing concrete at this point. It is a feature we want, though 🙂

This will be available in the next version of Jest via #9801.
