[Feature]: Configure screencast screenshot resolution

[mxlnk]

🚀 Feature Request

Make screenshot resolution configurable like the video option is.

The idea would be to allow to overwrite const kScreencastOptions = { width: 800, height: 600, quality: 90 }; in tracing.

Example

import { defineConfig } from '@playwright/test';

export default defineConfig({
  use: {
    // Capture screenshot after each test failure.
    screenshot: {
      mode: 'only-on-failure',
      size: {
        width: 800,
        height: 600
      }
    }
  },
});

Motivation

• We would like to have higher resolution screenshots.
• More consisten API
• sometimes hard to figure out small text in the screencast

Would a pull request implementing this have a good chance of getting merged?

You're referring to two distinct concepts of screenshots. The "screencast" you link to is the series of images that powers the movie strip at the top of the trace viewer. The use.screenshot config option in your snippet is about taking a screenshot at the end of a test and storing that as an attachment. Which of the two would you like to configure?

We were interested in configuring the resolution of the movie strip, not the screenshot at the end

Can you tell us more about your use case?
