unknown error: DevToolsActivePort file doesn't exist launching ChromeDriver using robot framewo-CodePudding

I have robot framework which will try to run the UI testing in headless mode. But when we run the robot framework inside Docker container, we got the below error

WebDriverException: Message: 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.)

Dockerfile:

FROM python:3.8

ENV JAVA_OPTS "-Dlog4j.formatMsgNoLookups=true"
ENV LOG4J_FORMAT_MSG_NO_LOOKUPS=true
ENV WAIT_VERSION 2.7.2

How to fix this issue?

CodePudding user response：

To get across the error:

WebDriverException: Message: 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.)

you can add the argument --no-sandbox as follows:

    Call Method    ${chrome_options}   add_argument    headless
    Call Method    ${chrome_options}   add_argument    --no-sandbox   # newly added argument
    Call Method    ${chrome_options}   add_argument    disable-gpu
