1. What is Jenkins?<\/strong><\/h3>\n\n\n\n

Jenkins is an open-source automation tool used for Continuous Integration (CI) and Continuous Delivery (CD). It helps automate build, test, and deployment processes.<\/p>\n\n\n\n

2. What is Continuous Integration (CI)?<\/strong><\/h3>\n\n\n\n

CI is a development practice where developers frequently merge code into a shared repository, and automated builds\/tests are triggered to detect issues early.<\/p>\n\n\n\n

3. What is Continuous Delivery (CD)?<\/strong><\/h3>\n\n\n\n

CD is the process of automatically preparing code changes for release to production after successful testing.<\/p>\n\n\n\n

4. Why is Jenkins used in Automation Testing?<\/strong><\/h3>\n\n\n\n
    \n
  • Automates test execution<\/li>\n\n\n\n
  • Supports scheduled execution<\/li>\n\n\n\n
  • Integrates with Selenium, Maven, Git, TestNG<\/li>\n\n\n\n
  • Generates reports<\/li>\n\n\n\n
  • Helps in CI\/CD pipeline<\/li>\n<\/ul>\n\n\n\n

    5. What are the advantages of Jenkins?<\/strong><\/h3>\n\n\n\n
      \n
    • Open-source and free<\/li>\n\n\n\n
    • Large plugin support<\/li>\n\n\n\n
    • Easy integration with tools<\/li>\n\n\n\n
    • Platform independent<\/li>\n\n\n\n
    • Supports distributed builds<\/li>\n<\/ul>\n\n\n\n

      6. What is a Jenkins Job?<\/strong><\/h3>\n\n\n\n

      A Jenkins job\/project is a task or automated process configured in Jenkins, such as build execution or test execution.<\/p>\n\n\n\n

      7. What are the types of Jenkins Jobs?<\/strong><\/h3>\n\n\n\n
        \n
      • Freestyle Project<\/li>\n\n\n\n
      • Pipeline Project<\/li>\n\n\n\n
      • Multibranch Pipeline<\/li>\n\n\n\n
      • Maven Project<\/li>\n<\/ul>\n\n\n\n

        8. What is a Jenkins Pipeline?<\/strong><\/h3>\n\n\n\n

        A Jenkins Pipeline is a sequence of automated steps written as code to build, test, and deploy applications.<\/p>\n\n\n\n

        9. What is the difference between Declarative and Scripted Pipeline?<\/strong><\/h3>\n\n\n\n
        Declarative Pipeline<\/strong><\/td>Scripted Pipeline<\/strong><\/td><\/tr>
        Simple syntax<\/td>Complex and flexible<\/td><\/tr>
        Easy to maintain<\/td>Requires Groovy scripting<\/td><\/tr>
        Structured format<\/td>More customization<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

        10. What is Jenkinsfile?<\/strong><\/h3>\n\n\n\n

        A Jenkinsfile is a text file containing pipeline script written in Groovy that defines CI\/CD workflow.<\/p>\n\n\n\n

        Example:<\/p>\n\n\n\n

        pipeline {\n\u00a0\u00a0\u00a0agent any\n\u00a0\u00a0\u00a0stages {\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0stage('Build') {\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0steps {\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0echo 'Build Started'\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0}\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0}\n\u00a0\u00a0\u00a0}\n}<\/code><\/pre>\n\n\n\n
        11. What is Maven in Jenkins?<\/strong><\/h3>\n\n\n\n
        Maven is a build management tool used to compile code, manage dependencies, and run test cases in Jenkins.<\/p>\n\n\n\n
        12. How do you integrate Selenium with Jenkins?<\/strong><\/h3>\n\n\n\n
        Steps:<\/p>\n\n\n\n
          \n
        1. Create Selenium Maven project<\/li>\n\n\n\n
        2. Push code to GitHub<\/li>\n\n\n\n
        3. Configure Jenkins job<\/li>\n\n\n\n
        4. Add Git repository URL<\/li>\n\n\n\n
        5. Add Maven commands like: clean test<\/li>\n\n\n\n
        6. Execute build<\/li>\n<\/ol>\n\n\n\n
