Test Coverage Report Generator for Contracts

WHAT IT DOES This tool connects to your EVM wallet and generates test coverage reports for smart contracts by analyzing contract source code and test execution data. It reads contract source code, test files, and coverage metrics from local or linked repositories, and optionally reads on-chain transaction traces to infer which code paths have been executed. The tool presents coverage data in a visual format including line-by-line coverage indicators, function coverage, branch coverage, and overall coverage percentage. HOW TO USE Connect your Web3 wallet using the Connect button. Enter the contract source code in the Contract Source Code field. Enter test coverage data in the Test Results / Coverage Data field as a JSON object with fields for totalLines, coveredLines, functions (total/covered), and branches (total/covered). Enter the contract name in the Contract Name field (optional). Click "Generate Report" to produce a visual coverage report. Click "Load Sample Data" to populate fields with example data. Results appear in the Results card with coverage percentage, function coverage, branch coverage, and a visual line-by-line coverage map. TECHNICAL MECHANISM: COVERAGE DATA VISUALIZATION AND ANALYSIS The tool processes coverage data provided in JSON format, parsing metrics for lines, functions, and branches. It calculates coverage percentages as: (covered / total) * 100. The visual line-by-line coverage map displays each line as a colored square—green for covered, red for uncovered—with tooltips showing the line number and coverage status. The tool generates a summary including overall status (Good ≥80%, Fair ≥50%, Poor
