Code Coverage Tool

The tool ingests Java code coverage reports generated by Jacoco or Cobertura for Spring projects and surfaces actionable metrics. It is designed for developers, QA engineers, and release managers who need objective evidence of test effectiveness and to drive test suite improvements. It computes overall coverage and provides per-package, per-class, and per-method breakdowns, identifying which code paths remain untested. It supports multi-module Maven and Gradle builds typical of Spring ecosystems and can aggregate reports from multiple modules in a single view.

At its core, the tool parses standardized XML or JSON reports, validates data integrity, and computes weighted coverage using line and branch data when available. It applies user-defined thresholds and flags gaps that trigger alerts or recommended actions. It normalizes package structures to align with source trees, accounts for generated code exclusions, and supports historical comparison so teams can trace coverage drift over time. Advanced usage includes filtering by module, package, or class and exporting structured data for downstream analytics.

The unique value lies in seamless integration with Spring Tool Suite workflows, fast feedback during development, and precise gap identification across large codebases. Use cases include pre-merge checks in CI pipelines, quarterly code health reviews, and targeted test refactoring. Core features include report parsing, coverage aggregation, threshold-based status, targeted gap lists, historical trend data, and exports in JSON/XML. This tool helps teams improve reliability, reduce regressions, and optimize test investments without manual audit overhead.
