Thank you!

@corevo is there any way that I can use firefox headless?

[Yrds]

@limasigor2 This can be achieved by set the env MOZ_HEADLESS=1 before run selenium-side-runner

It work but i didn't any further tests

I rather figure out a way of doing it using the capabilities, so that the .side.yml can consolidate all that info.
It's a matter of parsing it to the js bindings, I'll look into it.
EDIT: it should be possible right now, using capabilities, I just don't know from the top of my head which one to pass.

Thanks for the great tool. I have it doing exactly what I need - but - I've been unable to set the Chrome default download directory. I'm pretty sure it's a prefs settings, but I can't seem to find the right combination to make it work. Here is what I'm using:

selenium-side-runner -c "chromeOptions.prefs=[{browser.download.manager.showWhenStarting=false, safebrowsing.enabled=false, browser.helperApps.neverAsk.saveToDisk=application/download, application/octet-stream, text/csv, application/vnd.ms-excel, application/msexcel, application/x-msexcel, application/excel, application/pdf, safebrowsing-disable-download-protection=true, download.default_directory=G:\Downloads\SideRunner}]" E:\ESPOcho5.side

I'd also be fine with setting this in a file somewhere, but I haven't been able to figure out how to use the side.yml file (format) for this.

I'd appreciate any pointers

Thanks!

@Yrds: Confirmed, the command

MOZ_HEADLESS=1 selenium-side-runner -c "browserName=firefox" project.side

works for me.

Another way (found here) is

selenium-side-runner -c "browserName=firefox moz:firefoxOptions.args=[-headless]" project.side

Note there must be "-" in argument.

BTW I tried some tests and must say that headless mode speeds up testing much more in Chrome than in Firefox. In Firefox there is almost no performance difference between headless and non-headless mode.

When I run
selenium-side-runner -c "chromeOptions.args=[headless]" myproject.side
the following error occur:

Test suite failed to run
   TypeError: Target browser must be a string, but is <undefined>; did you forget to call forBrowser()?

     at Builder.build (../../../../../usr/local/lib/node_modules/selenium-side-runner/node_modules/selenium-webdriver/index.js:574:13)

     at WebdriverEnvironment.setup (../../../../../usr/local/lib/node_modules/selenium-side-runner/node_modules/jest-environment-selenium/dist/index.js:36:32)

What I do wrong?
chromedriver 2.46

In non-headless mode tests are running fine.

@vlad-bordei Run it with option browserName=chrome:

$ selenium-side-runner -c "browserName=chrome chromeOptions.args=[disable-infobars, headless]" myproject.side

[vlad-bordei]

Thanks @mirao

It works. Thanks!

I get the following error when I run this command on headless ubuntu 18
selenium-side-runner -c "browserName=chrome chromeOptions.args=[headless, no-sandbox, disable-dev-shm-usage, disable-infobars] chromeOptions.binary='/usr/bin/google-chrome-stable'" siteTest.side

`Test suite failed to run

WebDriverError: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)`

Headless from Chrome75:

selenium-side-runner -c "goog:chromeOptions.args=[--headless,--nogpu] browserName=chrome"
