We've been attempting to run web-component-tester in an alpine docker container for our CI process but have been running into an issue. I'll include a the simplified version of the necessary files below but could you provide a Dockerfile in which you run wct on a linux-based docker container successfully?
Dockerfile
FROM alpine:latest
RUN apk add --update --no-cache nodejs nodejs-npm git chromium chromium-chromedriver openjdk8 xvfb udev ttf-freefont
ENV LAUNCHPAD_CHROME=/usr/bin/chromium-browser
WORKDIR /tmp
COPY . ./
RUN npm i -g yarn bower bower-art-resolver && \
bower install --allow-root && \
echo "strict-ssl false" > $HOME/.yarnrc && \
yarn
ENTRYPOINT ["/bin/sh"]
CMD ["test.sh"]
test.sh
npm run test

}
When test.sh is run it gives us a long stack trace of java files. I have beautified them below:

@joelgenter I am afraid I do not have any docker images tested with wct-headless. I tested wct-headless only with Travis CI containers. Still, I have one suggestion. I have tested it with polymer/web-component-tester 6.0.* and @t2ym/web-component-tester, but not tested it with polymer/web-component-tester 6.2.0. So you can try wct 6.0.

@joelgenter wct-headless is used with Travis CI container image in my project t2ym/i18n-format#test

@joelgenter I briefly searched for the same errors in the Internet and suspect that Selenium is failing to find the binary of Chrome browser with the given URL for ChromeDriver since a timeout exception (UrlChecker.TimeoutException) is thrown from UrlChecker class, whose documentation is shown in the below URL. So you can check the path to the browser binary and its corresponding configuration for ChromeDriver.

@t2ym I tried knocking wct version down to 6.0.* to no avail. The ChromeDriver path was an issue that we resolved by setting an environment variable that pointed to chromium-chromedriver. We ended up deciding to run the tests with Xvfb. But I appreciate your help and prompt replies.
