-
Add Build Steps
Establish the build procedures for your task of automated testing. Typically, this entails running automated tests with testing frameworks like Selenium, creating the test environment, installing dependencies, and producing test reports.
-
Configure Post-Build Actions
Set up post-build steps to handle the test findings after the tests are run. For instance, make test results publicly available, archive artifacts, or start further tasks depending on test results.
-
Schedule Builds
Schedule the automatic execution of automation tests via Jenkins. Depending on your testing requirements, you can use different triggers, plan builds at regular intervals (such as nightly builds), or schedule builds in response to code changes.
-
Monitor and Analyze Results
Keep a regular eye on Jenkins builds for automated testing. Utilize the reporting plugins, test result trends, and integrated dashboards in Jenkins to track overall test coverage, discover failures, and evaluate test results.
-
Integrate with CI/CD Pipelines
If you’re using Jenkins, automated testing jobs should be integrated into the continuous integration and deployment (CI/CD) pipeline. This guarantees that software delivery processes include automated testing.
-
Ongoing Enhancement
Maintain and enhance your Jenkins Configuration for automated testing regularly. To improve overall testing efficiency, update test scripts, add new tests for features being added, optimize test execution times, and take comments into account.
Following these steps will help you efficiently set up Jenkins for automation testing and optimize the testing procedures inside your development workflows.
Best Practices for CI with Jenkins
The following are some recommended practices for Continuous Integration (CI) with Jenkin:
-
Use Version Control
Git and other version control systems offer an organized method for managing your codebase. They allow team members to work together, make code reviews easier, and ensure that changes are monitored over time. One can integrate Jenkins with your version control system to provide a smooth workflow that enables automated tests to be started automatically when changes are made to the code. It promotes a dependable and consistent testing procedure.
-
