# The Taiko installation downloads and installs the chromium required to run the tests. 
# However, we need the chromium dependencies installed in the environment. These days, most 
# Dockerfiles just install chrome to get the dependencies.

Error

Running the image with the following command

docker run  --rm -it -v ${PWD}/reports:/gauge/reports gauge-taiko

Executes the tests sucessfully but fails in generating the html report

RUN gauge install html-report --version 4.0.10

Can you try changing this to

RUN gauge install html-report

Hi thanks for your answer @sriv I only see that :
Unable to connect to plugin Html Report 4.1.4. rpc error: code = Unavailable desc = error reading from server: EOF
The tests are running fine

[sriv]

that isn't very helpful. I'll try to see if I can replicate this in my local.

Sorry :( I don't know if I can turn on some verbose setting ? I can share my Jenkinsfile :

pipeline {
    agent {
        label 'main'
    }
    tools {
        'org.jenkinsci.plugins.docker.commons.tools.DockerTool' 'Docker_20'
    }
    stages {
        stage('Build') {
            steps {
                sh "docker build -t gauge-taiko ."
                sh "docker run  --rm -i -v ${WORKSPACE}/reports:/gauge/reports gauge-taiko"
            }
        }
    }
}

Sorry, I wasn't implying that your report isn't helpful, rather was blaming the logs (and us indirectly, since we didn't capture enough details).

[pjvilloud]

FYI, the error message disappeared in my last builds. No clue why :)

Now the html report directory is not exported into the Jenkins workspace, but it's probably my configuration that needs an adjustement.

Thanks anyway and keep up the good work !
