Code Coverage Execution and Maximization Guide

This developer skill provides step-by-step instructions and best practices for executing code coverage tools, identifying untested paths (gaps), and writing high-fidelity unit tests to drive coverage to 100% across the monorepo.

1. Executing and Aggregating Monorepo Coverage

Our monorepo coordinates testing across multiple packages using Melos. Follow this command workflow to generate and merge coverage data:

A. Run Package Tests with Coverage

Execute the monorepo test runner. This runs flutter test --coverage (or dart test --coverage) across all packages:

melos run test
