In the Selenium options (on Firefox) I can find Custom browser
.
Is it possible to use this option to run a Selenium test in Chromium Browser (not Chrome)?
Uh, the accepted answer doesn't answer the question. Google Chrome is based on Chromium, but they're not the same browser.
This is what you want: (since Chromium isn't officially supported)
DefaultSelenium selenium = new DefaultSelenium("localhost", 4444, "*custom C:/path/to/chromium.exe" , "www.google.com");
selenium.start();
Edit 2018-08: Looks like the accepted answer changed to a copy of this one several years later, so my original comment is no longer correct. I'm leaving it there, but struck out, because the votes are misleading if I straight remove it.
