[GSoC 2026 Proposal] Improving Trend Visualization and Data Integrity for Cucumber Reports - Kushagra Tiwari

Introduction

Hi everyone! I am Kushagra Tiwari, a developer focused on Java backend systems and data visualization. I am excited to submit my proposal for the 2026 Google Summer of Code to work on the Cucumber Reports ecosystem within Jenkins.

I have been an active contributor to the project over the last few weeks, working closely with the maintainer, @damianszczepanikdamianszczepanikdamianszczepanikdamianszczepanik, to improve the accuracy of test reporting.


Contribution History (Proven Experience)

Before drafting this proposal, I focused on resolving existing logic errors to stabilize the reporting engine.

  • [Merged/Approved] PR#1329: Refactored TrendsOverviewPage to correct the “Passed” metric calculation logic.

  • [Merged/Approved] PR#1333**:** Implemented a “Total” baseline for Trend Statistics charts to improve high-level suite visibility.

  • Technical Impact: These fixes involved deep-diving into the Java backend, Velocity templates, and ensuring compatibility with the AppVeyor integration suite (600+ tests).


Project Goal: Accuracy, Interactivity, and Scalability

The goal of my project is to move the Cucumber Reports plugin from “Static Reporting” to “Actionable Intelligence.”

  1. Data Integrity Audit: A full audit of JSONParser and ReportBuilder to ensure “Skipped” and “Pending” statuses are handled with 100% mathematical accuracy across all charts.

  2. Modernized Frontend: Upgrading the Chart.js implementation to support dynamic legend toggling and high-DPI responsive scaling for modern DevOps dashboards.

  3. Performance Optimization: Refactoring the StatusAggregationEngine to reduce memory overhead when processing large-scale JSON reports (100MB+).


Draft Roadmap

  • Community Bonding: Finalizing design docs and identifying legacy code blocks for refactoring.

  • Phase 1 (Logic): Implementing the centralized Status Aggregation Engine and expanding the JUnit test suite for edge-case JSON inputs.

  • Phase 2 (UI/UX): Modernizing the trends-chart.js.vm and implementing interactive tooltips/filtering.

  • Final Phase: Documentation, performance benchmarking, and final polish.

I would appreciate any feedback from mentors and the community!
