I intend to test fatch with mocha. I am using testing fetch with mocha and chai to get started but kept running into multiple errors. Not sure what I am doing wrong.
Here is the test code:
var jsdom = require('mocha-jsdom')
global.document = jsdom();
const chai = require( 'chai' ).assert;
const fetch = require("node-fetch");
const chaiHTTP = require("chai-http");
const index = require('../client/js/index');
chai.should();
chai.use(chaiHTTP)
described('Index', function(){
jsdom()
it( "sends a fetch request", async () =>{
// chai.request(index)
await fetch("https://anapioficeandfire.com/api/books")
.then((res) => {
return res.json()
})
.then((res) => {
console.log(res);
assert.equal(res, true)
})
})
})
This throws the following error :
TypeError: Cannot read property 'querySelector' of undefined
//index.js
function fetchBooks(){
fetch(`https://anapioficeandfire.com/api/books`)
.then(res => res.json())
.then(renderBooks)
}
const main = document.querySelector('#main')
function renderBooks(data) {
data.forEach(book => {
h2.innerHTML = `<h2>${book.name}</h2>`
})
}
