0upvotes

Analyze existing test suites and source code to suggest additional unit tests that improve test coverage. Use this skill when working with test files and source code to identify untested code paths, missing edge cases, uncovered branches, untested error conditions, and gaps in test coverage. Supports major testing frameworks (pytest, Jest, JUnit, Go testing, etc.) and generates targeted test suggestions based on coverage analysis.

# Coverage Enhancer

Analyze existing tests and source code to identify coverage gaps, then suggest specific additional tests to improve overall test coverage and code quality.

## Core Capabilities

### 1. Coverage Gap Analysis

Identify untested areas in source code:
- **Uncovered lines** - Code never executed by tests
- **Uncovered branches** - Conditional paths not tested
- **Uncovered functions** - Methods/functions without tests
- **Missing error handling tests** - Exception paths not verified
- **Untested edge cases** - Boundary conditions not covered
