feat: mock route for ppt

[kobenguyent]

Motivation/Description of the PR

Network requests & responses can be mocked and modified. Use mockRoute which strictly follows Puppeteer's setRequestInterception API.

I.mockRoute('https://reqres.in/api/comments/1', request => {
  request.respond({
    status: 200,
    headers: { 'Access-Control-Allow-Origin': '*' },
    contentType: 'application/json',
    body: '{"name": "this was mocked" }',
  });
})

I.mockRoute('**/*.{png,jpg,jpeg}', route => route.abort());

// To disable mocking for a route call `stopMockingRoute`
// for previously mocked URL
I.stopMockingRoute('**/*.{png,jpg,jpeg}'

To master request intercepting use HTTPRequest object object passed into mock request handler.
