What is continuous integration?

  • Automated Build with immediate feedback
  • Auto Testing with immediate feedback

Details short version of continuous integration?

  • Automated Code Review with immediate feedback
  • Automated Build with immediate feedback
  • Automated Unit testing with immediate feedback
  • Automated Packaging with immediate feedback
  • Automated Package archive with immediate feedback
  • Automated Deployment to QA, UAT, Stageing env with immediate feedback
  • Automated Acceptance Testing with immediate feedback
  • Automated Code Coverage with immediate feedback

For achieving this, You need to integrate many tools such as following in Java Stack

  • Automated Code Review with SonarQube
  • Automated Build with Maven
  • Automated Unit testing with Junit
  • Automated Packaging with Jar
  • Automated Package archive with Nexus
  • Automated Deployment to QA, UAT, Staging env with Ansible
  • Automated Acceptance Testing with Selenium
  • Automated Code Coverage with Jacoco.

Thus, we need one tool which can be integrated with SonarQube, Maven, Junit, Jar, Nexus, Ansible, Selenium and Jacoco and the tool is Jenkins.
