Launch in background

I know this is out of scope but out of interest…

I didn’t find a way to specify opening the browser in the background. Stealing focus from the terminal window is just unwanted, for most cases, I guess.

I think it should be default.

There’s a flags thing. I read the manual. There’s nothing. Perhaps a trick with --display?

It points to this and this, which also don’t seem to have what is required. Perhaps something with --class?

This is relevant for all the other “real” browser launchers, as well.

I too would like the ability to launch the browsers minimized or in the background. Very annoying to have to keep minimizing the screens manually. Did you find a solution?

I’ve seen this been suggested:

browsers: [
    'ChromeBackground'
],
customLaunchers: {
    ChromeBackground: {
        base: 'Chrome',
        flags: ['--no-startup-window']
    }
},

While that works and launches Chrome in the background, Karma doesn’t seem to detect the browser. So I’ve resorted to just making the window less obnoxious:

browsers: [
    'ChromeSmall'
],
customLaunchers: {
    ChromeSmall: {
        base: 'Chrome',
        flags: ['--window-size=300,300']
    }
},

@AdamBuczynski Thanks for your answer. I use --window-position=-9999,0.
