The same like normal Jest configuration, you can load jQuery in your Jest setup file. For example your Jest setup file is `setupJest.ts` you can declare jQuery: | ||
|
||
``` | ||
window.$ = require('path/to/jquery'); | ||
`` | ||
|
||
or | ||
|
||
``` | ||
import $ from 'jquery'; | ||
global.$ = global.jQuery = $; | ||
``` | ||
|
||
The same declaration can be applied to other vendor libraries. | ||

No, by master I mean master changelog. The first line of this file states:
