Webdriver (selenium-standalone) tests with chromium - not starting ECONNREFUSED (on Apple M1) - docker

Question

our end to end tests run in a docker container and use Webdriver.io - with selenium-standalone.
Since updating to an M1/arm64 Mac I've been trying to update the tests to run.
Our unit tests (jest) were fixed easily by changing from using the ./google-chrome-stable_current_amd64.deb to using chromium.
Test container dockerfile:
FROM node:14-bullseye
ENV CHROME_BIN=/usr/bin/chromium
RUN apt-get update \
&& apt-get install -y chromium \
openjdk-11-jre \
xvfb \
x11vnc \
php \
&& mkdir ~/.vnc \
&& x11vnc -storepasswd "fakepwd" ~/.vnc/passwd \
&& rm -rf /var/lib/apt/lists/*
COPY ./entrypoint.sh /usr/local/bin/
ENTRYPOINT ["entrypoint.sh"]
I hoped it would be as simple for webdriver tests but no luck so far.
I've upgraded #wdio packages as below:
"#wdio/allure-reporter": "^7.10.1",
"#wdio/cli": "^7.19.3",
"#wdio/devtools-service": "^7.19.3",
"#wdio/junit-reporter": "^7.19.1",
"#wdio/local-runner": "^7.19.3",
"#wdio/mocha-framework": "^7.19.3",
"#wdio/selenium-standalone-service": "^7.19.1",
"#wdio/sync": "^7.19.3",
In the lock file I've confirmed the selenium-standalone version is 7.1.
(As above we use 7.19.1 of #wdio's service - this uses ^7.0 but only 7.1 works for M1's: https://github.com/webdriverio/selenium-standalone/commit/10e31d0e20444b0f6eb2d897cb3b471782dd243d)
I've confirmed that the correct chromedriver binary is used too (under ./node_modules/selenium-standalone/.selenium/chromedriver is 99.0.4844.51-arm64)
From wdio.conf.js:
services:[['selenium-standalone',{
installArgs: {
drivers: {
chrome: {
binary: '/usr/bin/chromium',
version: chromeDriverVersion,
arch : process.arch,
baseURL : 'https://chromedriver.storage.googleapis.com'
}
}
},
args: {
drivers: {
chrome: {
binary: '/usr/bin/chromium',
version: chromeDriverVersion,
arch : process.arch
}
}
}
}]];
capabilities: [{
browserName: process.env._BROWSER,
acceptInsecureCerts: true,
maxInstances: 4,
'goog:browserOptions': {
binary: '/usr/bin/chromium', // may not be needed, tried anyway
args: process.env._ENABLE_UI === 'false' ?
['--disable-dev-shm-usage','--no-sandbox','--headless','--disable-infobars','--deterministic-fetch', `--window-size=${default_viewport_width},${default_viewport_height}`] :
['--disable-dev-shm-usage','--no-sandbox','--disable-infobars', `--window-size=${default_viewport_width},${default_viewport_height}`]
}
}],

I presume it's chromium having an issue starting - but I can't find any relevant logs.
I've tried to start it inside the container manually, but I have no idea if there's anything useful here:

Any help would be appreciated, thanks!

Answer 1

It turns out that the "drivers" section must use "chromium" and not "chrome"
And for "capabilities" it should be "chrome"
I can't explain why unfortunately as selenium/webdriver docs seem to only mention chrome as the driver, not chromium - but this is the only way to get it to work
I.e.
const drivers = {};
drivers[process.env._BROWSER] = {
binary: '/usr/bin/chromium',
version: chromeDriverVersion,
arch : process.arch,
baseURL : 'https://chromedriver.storage.googleapis.com'
};
services:[['selenium-standalone', {
installArgs: {
drivers: drivers
},
args: {
drivers: drivers
}
}]];
capabilities: [{
browserName: process.env._BROWSER === "chromium" ? "chrome" : process.env._BROWSER,
...
