Integrating Jenkins with Git

To create the most of Jenkins, you first postulate to connect it with your source code repository. This guarantee that every new commit automatically actuate a test run, keeping your feedback loop short and reliable.

• In Jenkins, create a new project or open an existing one.
• Under Source Code Management, select Git.
• Enter your repository URL. You can use HTTPS or SSH depending on your setup.
• If your repository is private, add credentials such as a username/password or an SSH key.
• Specify the branch you want Jenkins to trail, such as main or develop.

Once configured, Jenkins will be able to bring the latest code and ensure your test runs are invariably in sync with your repo.

Setup Job to Run Automated Test with Jenkins

After integrating with Git, the adjacent step is to configure a Jenkins job to run your automated tests. You can do this using either aFreestyle project or a Pipeline job, depend on your orientation and undertaking demand.

For a Freestyle project:

• Go to Build Triggersand enable options likeBuild periodically or Build when a modification is pushed to Git.
• In the Buildsection, add stairs such as:
  
  • Uploading your application bod (e.g., .apk or .ipa) to HeadSpin using the REST API.
  • Running your tryout script through the command line interface, for example with Appium or another tryout framework.
• Add any necessary post-build steps, such as cleanup or report generation.

For a Pipeline job:

• Define the stage straightaway in a Jenkinsfile in your repository.
• Use steps to clone the code, upload the app to HeadSpin, execute tests, and archive results.

For autonomous testing across multiple user personas, check out SUSATest — it explores your app like 10 different real users.

This setup ensures that your automated exam run reliably every time Jenkins detects a new build.

Executing the Job

With the job configure, you ’ re ready to run it.

• From your Jenkins dashboard, select the job and pawlBuild Now.
• Monitor procession inConsole Output, where you ’ ll see logs for each step—cloning the repo, uploading the app, running tests, and reporting.
