A Jenkins CLI utility that shows a diff of failing tests between two builds

• Shows a diff of failing tests between two builds of same branch or different branched within a repo.
• Output retrieved displays the build name, test name and age of failing tests

• Clone repo to preferred folder
• CD into folder and run npm install
• To run, use command JIRA_USERNAME=YOUR_JIRA_USERNAME JIRA_PASSWORD=YOUR_JIRA_PASSWORD JENKINS_USERNAME=YOUR_JENKINS_USERNAME SERVER_URL=YOUR_JENKINS_SERVER_URL SERVER_PORT=YOUR_JENKINS_SERVER_PORT TEST_PIPELINE=YOUR_TEST_PIPELINE nohup node main.js
  • You can add the environment variable on your system PATH so that you don't have to pass them when running
  • nohup allows you to store output from the terminal to a nohub.out file
• Once running you will be presented with a jenlytics consoles shown as jenlytics$
• To get a diff of the failing tests between two branches say branch BRANCH-100 build 10 and branch MASTER build 50, enter the following command:
  • diff BRANCH-100#10 MASTER#50 where the branch is separated with the build number by a # then press enter and you'll be presented with results in table format with three columns namely Build, Test and Age

• Make it an npm module so that it can be installed globally and executed from anywhere
• Add more features like:
  • diff newest branches of the two builds if build number specified
  • Viewing history of failing test in a branch from all past builds
  • Viewing cause of failure
  • Diff more than two diffs
  • Graphing the results
  • More analytics
• Make an desktop/web version
