Window Size

[Houbein]

Describe the bug The viewport argument of New Context does not work. According to the documentation; the New Context keyword has an argument viewport that allows you to set the width and hight to 0 so it will scale automatically with the window. This does not happen. If I set these values to 0, all I get is a tiny window that does not scale at all. To Reproduce Steps to reproduce the behavior:

1. New Browser browser=chromium
2. New Context with viewport={'width': '0', 'height': '0'} *Expected behavior A browser window that detects my window size and automatically scales to that size.

Desktop (please complete the following information):

• OS: [Wihndowsw 10 22H2 19045.5011]
• Browser Chrome]
• Version [130]

Does it behave differently than in this video? I tried it and it works exactly as expected.

Yes the window is small, but if you resize the window, the viewport resizes/scales together with the outer size.

Viewport is window.innerWidth and window.innerHeight . The window that you as a user might resize is window.outerWidth and window.outerHeight.

With a fixed viewport the page always has the same size independently of the screen size. This can also be bigger than the outer size.

If your seen behaviour is still a different one, please describe more.

Ah, I'm sorry I misinterpreted the documentation to mean that with viewport 0 it would always open scaled to the full resolution of my browser.

@Houbein

you may also want to look at #2054

you can set the viewport to ${NONE} and give the following argument to New Browser args=["--start-maximized"]
