    TypeError: require(...) is not a function

tested-module.test.js

jest.dontMock('yargs');
var path = require('path');
var testedModule = require('./tested-module');

test('empty', () => {
  testedModule( '--help')
});

tested-module.js

var yargs = require('yargs');

function testedModule(input) {
  yargs.help();
  yargs.usage(input);
}

module.exports = testedModule;

What is the expected behavior?

Tests would be able to load and use the yargs module. The failed line is this dynamic require in yargs
