A node utility for Jest to create a mocked document.body from a local HTML file.
Jest provides a mocked document object in your tests, but document.body is empty. You could do document.body.innerHTML = '<div id="app"/>' in your beforeEach hook, but if you need much more HTML than that it can be annoying to write or read it as a JS string. mockument allows you to use an HTML file instead.
Pass the mockument function the absolute path to an HTML file from which you want to generate a document.body object. mockument will modify Jest's document object and set its document.body to the one generated from the <body> of the HTML file.
Usage example:
import mockument from 'mockument'
describe('something', () => {
beforeEach(() => {
mockument(`${__dirname}/../../public/index.html`)
})
})Note: mockument uses and modifies Jest's document object, so it will only work if used somewhere where Jest provides it's mock document object in scope. It won't be able to find the document object if used in other nodejs contexts. (And it won't be able to find node's 'fs' module if used in the browser either!)
