Chromium as snap package (Ubuntu 19.10+)

[michaelzangl]

Description of the problem:
Webdriver does not find the chromedriver for the ubuntu snaps package.
The ubuntu snaps package for chromium (default starting with Ubuntu 19.10) requires a patched version of the webdriver. That version is / can be installed with chrome locally. The previous work around of forcing a chrome version does not work, since it will download the unpatched chromedriver.

The command to start chromium is:

chromium --version

If the version ends with snap, the driver to use is:

/snap/bin/chromium.chromedriver

It is important to use that binary and to not download it from anywhere else, since the snap sandboxing mechanism won't work when just downloading that binary.

Selenium currently has issues with this as well, so even if the auto-detection would work, the tests won't start. See SeleniumHQ/selenium#7788

Browser and version: Chromium 78.0.3904.97 snap

Operating system: Ubuntu 19.10

WebDriverManager version: 3.6.2

WebDriverManager.chromedriver().setup();
WebDriverManager.chromedriver().avoidAutoVersion().version(CHROME_VERSION).setup();

Workaround

if (new File("/snap/bin/chromium.chromedriver").exists()) {
	System.setProperty("webdriver.chrome.driver", "/snap/bin/chromium.chromedriver");
} else {
		WebDriverManager.chromedriver().avoidAutoVersion().version(CHROME_VERSION).setup();
}

Thanks for reporting. I'll take into account for the next version of wdm.

WebDriverManager 3.8.0 provides support for Chromium (also for snap packages):

WebDriverManager.chromiumdriver().setup();
