Automated JavaScript Testing APIs support the automation of Chrome Flags on your Google Chrome browser.

Overview

Chrome Flags are potential functionalities that you can enable, disable, or set as default to control the browser services and behavior. You can check all Chrome Flags using the chrome://flags/ URL on your Google Chrome browser.

Run test using Chrome Flags

Pass Chrome Flags in karma_conf.js to use Flags in your tests.

flags: ["--enable-features=WebContentsForceDark"] 

For example:

customLaunchers: { bs_chrome_win1: { base: 'BrowserStack', browser: 'chrome', browser_version: 'latest', os: 'Windows', os_version: '11', flags: ["--enable-features=WebContentsForceDark"] }, }, 

Following code snippet is a test script that enables dark mode using a Chrome Flag.
