javascript - how to use jsdom to test functions with 'document' -
i have small question.. trying test functions created (written in typescript), , using mocha/chai/jsdom. now, error while testing functions 'document' inside document.. message 'referenceerror: document not defined'. how can still test these functions 'document' in it?
for example:
[prompt.spec.ts]
import { expect } 'chai' import { jsdom } 'jsdom' import { functionx } './functions' describe('functions', () => { it('is possible execute functionx simple parameters', () => { const jsdom = new jsdom() const htmlelement = jsdom.window.document.createelement('div') expect(functionx(htmlelement, function() { return true; } )).to.equal(true) }) }) [functions.ts]
export const functionx = ( body:htmlelement, callback: (ok: boolean) => void ) => { const doc = body.ownerdocument const parent = doc.body // ... let container = document.queryselector('.container') htmldivelement // referenceerror: document not defined }
you can make jsdom's document available tests globally if prepare in advance.
import { jsdom } 'jsdom'; const { window } = new jsdom('<!doctype html><html><body></body></html>'); // save these 2 objects in global space libraries/tests // can hook them, using above doc definition. global.document = window.document; global.window = window; write separate file , add file parameter mocha right before spec files. like:
_mocha specs/_setup.js specs/*.js
