Running Gwen on Jenkins

Jenkins job

Since v3.16.0, the init --jenkins command was introduced to generate a Jenkins file in your project. You will need to create the file manually if you are using an older version.

To run your Gwen project in Jenkins, get your Gwen project running in Docker first. Then create a Jenkins pipeline file in your project as shown below.

Run the following command in the root of your project to generate a Jenkins pipeline file

yarn gwen init --jenkins

The following file will be created

./project                    # Your project root
└── /gwen
└──Jenkinsfile # Jenkins pipeline script file

With the following content

pipeline {
agent {
// replace with an agent that has docker installed
label 'docker-agent'
}
parameters {
choice(name: 'env', choices: ['dev', 'test', 'staging', 'prod'], description: 'Target environment')
choice(name: 'browser', choices: ['chrome', 'firefox', 'edge'], description: 'Target web browser')

booleanParam(name: 'parallel', defaultValue: false, description: 'Enable parallel execution')
choice(name: 'threads', choices: ['auto', '2', '4', '8', '12', '16', '24', '32', '48', '64'], description: 'Number of parallel threads (auto = one thread per available core)')
booleanParam(name: 'headless', defaultValue: false, description: 'Enable headless browser')
booleanParam(name: 'video', defaultValue: true, description: 'Enable video capture (not available with parallel or headless)')
}
