vscode automatic type acquisition for jest
You have a few options in this case:
Add jest
to your package.json
:
"dependencies": {
"jest": "^18.1.0"
}
This only works if you are working JavaScript and do not have a tsconfig.json
.
Install @types/jest
$ npm install -D @types/jest
This should work for both JavaScript and TypeScript projects. However @types
but may be disabled by a jsconfig.json
/tsconfig.json
: http://www.typescriptlang.org/docs/handbook/tsconfig-json.html
Create a jsconfig.json
file in the root of your workspace to specifically include jest:
{
"typeAcquisition": {
"include": [
"jest"
]
}
}
This will only work for JavaScript projects when automatic typings acquisition is enabled.
All of these should allow VSCode to pick up jest's typings without an import
or require
I tried installing the @types/jest
, and it did work, but the problem is that it resulted in the jest suggestions appearing in my .js
files as well. I couldn't figure out how to get global suggestions for test
, expect
, etc. in only .test.js
files but not .js
files.
So I decided to just manually import each jest global I was going to use in each .test.js
file, which allowed the suggestions to appear with types but avoided having the suggestions appear in the .js
files:
import { test, expect } from '@jest/globals'
