How to use the proxyquire.callThru function in proxyquire

import test from 'ava';
import { jsdom } from 'jsdom';
import sinon from 'sinon';
import proxy from 'proxyquire';
import camelcase from 'camelcase';

const sandbox = sinon.sandbox.create();
const castStub = sandbox.stub().returnsArg(0);
const camelSpy = sandbox.spy(camelcase);

proxy.noCallThru();
const metaProps = proxy('../src', {
    camelcase: camelSpy,
    './cast': castStub,
}).default;
proxy.callThru();

const doc = jsdom();
global.document = doc;

sandbox.spy(doc.head, 'querySelectorAll');
sandbox.stub(console, 'warn');

test.beforeEach(() => {
    sandbox.reset();
    doc.head.innerHTML = ''; // reset meta tags
});

test('no props returns empty object', (t) => {
    t.deepEqual(metaProps(), {});
});
