slowMo in launch options is not passed correctly

[achwilko]

Unfortunately, slowMo (https://playwright.dev/#version=v1.2.0&path=docs%2Fapi.md&q=browsertypelaunchoptions--options-slowmo) param is not passed correctly in jest-playwright launch options.

To reproduce, try below jest-playwright.config file:

// jest-playwright.config.js
module.exports = {
  launchOptions: {
    args: ['--no-sandbox', '--disable-dev-shm-usage'],
    headless: false,
    slowMo: 250,
  },
  browsers: ['chromium'],
};

• OS: Windows
• playwright version 1.1.1.
• jest-playwright-preset version 1.2.1

@achwilko thank you for report. There is some issue with passing connectOptions.
Also I got some notes to specify what is wrong with it.
jest-playwright under hood is launch browser server by default. After this it will connect to running server and it will use connectOptions passing through the config.
In next release we made this process configurable. So you can just launch the browser:

// jest-playwright.config.js
module.exports = {
  launchType: 'LAUNCH',
  launchOptions: {
    args: ['--no-sandbox', '--disable-dev-shm-usage'],
    headless: false,
    slowMo: 250,
  },
  browsers: ['chromium'],
};

Also I just made a fix in #202 to pass connectOptions, so after it, you can do something like this:

// jest-playwright.config.js
module.exports = {
  launchOptions: {
    args: ['--no-sandbox', '--disable-dev-shm-usage'],
    headless: false,
  },
  connectOptions: {
    slowMo: 250,
  },
  browsers: ['chromium'],
};

@mmarkelov that's great, thanks for the information. I will use connectOptions with the next release. Thanks for all your hard work done for jest-playwright-preset 🍻

@achwilko just published new next release, that should fix this issue

@mmarkelov I've just tested 1.3.0-rc2 version and it's working as expected 👍 Once more, thanks for your support and update 💯
