Play around!

We have set up the following so you can learn and test the workflow:

• repository: https://github.com/changtengfei/demo_github_jenkins_repo

• associated Jenkins job: https://builder.openwsn.org/job/demo_github_jenkins_job/

Workflow for Contributors

• Fork the target repository

  • Log into your GitHub account

  • Go to repository: https://github.com/changtengfei/demo_github_jenkins_repo and click the “fork“ button on the right side of repository name

• Create an issue

  • Go to https://crystalfree.atlassian.net/secure/BrowseProjects.jspa and select the project you are working on

  • Click the “+“ on the left bar of the page to create an issue in Jira system

    • Fill the Summary of the issue and the description if necessary

    • Assignee to yourself if you are the one working on the issue

    • Click “Create“ to create an issue

    • In the issue page, change the STATUS to IN PROGRESS

• Work on the issue

  • Clone the repo just forked on your local computer with following command:

    • git clone https://github.com/[GitHub Account]/demo_github_jenkins_repo

  • By default, you will be on “master“ branch. Create a new branch based on the “master“ branch. Use a name starting with the issue ID, such as, “SW-4”. This allows Jira hook the branch link in the issue page.

    • git branch # make sure you are on master branch

    • git checkout -b [name_of_your_new_branch] # create a new branch

  • You will work on the issue/task and commit your code into the created new branch. Use commit message starting with issue ID, such as “SW-4. fix…“, allows Jira system hook the commit link in the issue page.

• Create a pull request

  • When you resolve your issue or finish the task, make sure you have commit all your work to the branch and push the changes to GitHub with following command

  • Go to the issue page and change the STATUS to RESOLVED

• Verify the tests pass

  • Your repository contains the tests to run (see writing tests )

  • Opening a pull request causes the Jenkins build to start and test your branch, automatically. The result of that test appears directly in the PR on GitHub.
