Understand how to create a CI pipeline in Azure DevOps that builds a Docker image from your Selenium Java test project and runs the tests inside a container. This lesson guides you through building and executing a pipeline using YAML, setting environment variables for browser configuration, and viewing test results.

RUN apt-get install openjdk-8-jdk -y
 
ENTRYPOINT ["bash", "command.sh"]

The Docker pipeline YAML code is below:

YAML
trigger:
- master
pool:
  vmImage: 'ubuntu-latest'
steps:
- task: Bash@3
  displayName: 'Create Java Test Image'
  inputs:
   targetType: inline

- task: Bash@3
  displayName: 'Run Java Test Container'
  inputs:
   targetType: inline
   script: 'docker run -e "BROWSER=chrome" --name tests seleniumtests'

The pipeline has only two tasks, one for building the Docker image and ...
