slowMo not working

[Diokuz]

My root jest-puppeteer.config.js:

const isDev = true

module.exports = {
  server: {
    command: 'node puppeteer/server.js',
    port: 1337,
  },
  launch: {
    // dumpio: true,
    slowMo: 1200,
    headless: !isDev,
    executablePath: isDev ? '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' : undefined,
  },
}

But no slowMo detected: tests are executed as fast as possible, nothing can be observed. Is there any secrets on how to switch on the slowMo flag?

I just tested it and it does not work, it should be a Puppeteer issue because, all options specified in launch are passed to Puppeteer.launch, is this option working without Jest Puppeteer?

You can also set the slowMo property in the options object parameter for puppeteer.connect. I believe this is missing in the PuppeteerEnvironment class where puppeteer.connect is called.
