How to automatically run visual testing?

[linonetwo]

I want to test my game like electron app with playwright.
Which will get a reference to the app GUI as this.app, and can dispatch mouse and keyboard event to the app reference.

App runs like how end user will see it, and can take screenshot in the CI, so easy to see how step goes wrong

      # Install minimal Linux dependencies for Electron GUI testing https://www.electronjs.org/docs/latest/tutorial/testing-on-headless-ci
      - name: Install Linux GUI dependencies
        run: |
          sudo apt-get update
          sudo apt-get install -y xvfb
          # Install Chinese fonts and locale support for i18n testing
          sudo apt-get install -y fonts-noto-cjk fonts-wqy-zenhei language-pack-zh-hans
          sudo locale-gen zh_CN.UTF-8
      - name: Run tests
        # E2E GUI tests with Electron on Linux require a virtual framebuffer, upgrade screen size from time to time.
        run: xvfb-run --auto-servernum --server-args="-screen 0 2560x1440x24" pnpm run test
        env:
          CI: true
          DISPLAY: :99
          # Set Chinese locale for i18n testing
          LANG: zh_CN.UTF-8
          LC_ALL: zh_CN.UTF-8
        timeout-minutes: 15

Can bevy do that? I tried cucumber_rs, but always find hard to share the graphical instance with test.

I see, most of examples are empty. And I have some try these days, I find all events has to be in ron file, can't dynamically send in the e2e test?

When testing electron, we may write mouse move and click in the test file, but we can't do this in bevy's test?
