Contributions summary:Vishnu primarily contributed to the improvement of code coverage by modifying test files and reporters to ensure accurate percentage calculations. Their work included modifying existing test cases, adding new tests for precision, and fixing reporting logic in Cobertura and OpenCover reporters to provide correct branch and line coverage percentages. They also addressed an issue in `CoverageDetails.cs` to return 100% when no lines exist. The user also focused on modifying test cases to improve the arithmetic precision for line and branch coverage calculations and fixing exit codes for specific failures.
