description | Increase test coverage by targeting untested branches and edge cases |
Expand existing unit tests adapted to project's testing framework:
- Analyze coverage: Run coverage report to identify untested branches, edge cases, and low-coverage areas
- Identify gaps: Review code for logical branches, error paths, boundary conditions, null/empty inputs
- Write tests using project's framework:
- Jest/Vitest/Mocha (JavaScript/TypeScript)
- pytest/unittest (Python)
- Go testing/testify (Go)
- Rust test framework (Rust)
- Target specific scenarios:
- Error handling and exceptions
- Boundary values (min/max, empty, null)
- Edge cases and corner cases
- State transitions and side effects
- Verify improvement: Run coverage again, confirm measurable increase
Present new test code blocks only. Follow existing test patterns and naming conventions.
