The goal of this project is to make it possible to identify flaky tests by aggregating test failure data from RHBA Jenkins.

The project consists of 2 parts:

• A Haskell program which
  • downloads test results of all unstable builds of jobs from master pullrequests folder of RHBA Jenkins. For each failure it saves 5 items: job URL, test class and test method name, stack trace and date of build.
  • searches for the path of each test class within local filesystem (starting from folder where all kiegroup repositories are cloned) in order to provide GitHub link functionality.
• A single page Elm application which enables browsing data scraped by the above script. This is deployed at janhrcek.cz/random-failures/ and updated with new data on weekly basis.

RHBA Jenkins is only archiving last 14 days of builds. So it's necessary to periodically (~ once a week) scrape test failure data. The data are persisted in a JSON file, which is then deployed to the gh-pages branch of this repository together with the interactive HTML application for browsing it.

The process of scraping is automated, everything can be done by just running ./cli.sh at the root of this project. The script will

1. build and run the scraper program, which outputs all the failures into frontend/dist/failures.json
2. build and runs the front end report
3. copy the contents of the frontend/dist to the root directory of this repo at gh-pages branch
4. push the updated report to the gh-pages branch
