I like to run my karma unit tests on a headless chrome. Using karma-chrome-launcher and setting the browser to "ChromeHeadless" works on my machine. But on the CI server it fails with the message "No binary for ChromeHeadless browser on your platform." Installing chrome on the CI machine is not possible. Is there another way to load the chrome binaries? for example the google puppeteer module seems to load that when run. from the docs: "Puppeteer downloads and uses a specific version of Chromium". How can i achieve the same?

Which command starts the google chrome web browser in headless mode? As we have already seen, you just have to add the flag –headless when you launch the browser to be in headless mode. With CLI (Command Line Interface), just write: chrome \<br> – headless \ # Runs Chrome in headless mode.
Note: Headless mode has been available on Mac and Linux since Chrome 59. Windows support came in Chrome 60.
You can run Google Chrome in headless mode simply by setting the headless property of the chromeOptions object to True. Or, you can use the add_argument() method of the chromeOptions object to add the –headless command-line argument to run Google Chrome in headless mode using the Selenium Chrome web driver.
You can use Puppeteer (headless Chromium), follow these instructions.
