name: Expand Unit Tests description: Increase test coverage by targeting untested branches and edge cases tags: testing, coverage, unit-tests

Expand Unit Tests

Expand existing unit tests adapted to project's testing framework:

1. Analyze coverage: Run coverage report to identify untested branches, edge cases, and low-coverage areas
2. Identify gaps: Review code for logical branches, error paths, boundary conditions, null/empty inputs
3. Write tests using project's framework:
4. Jest/Vitest/Mocha (JavaScript/TypeScript)
5. pytest/unittest (Python)
6. Go testing/testify (Go)
7. Rust test framework (Rust)
8. Target specific scenarios:
9. Error handling and exceptions
10. Boundary values (min/max, empty, null)
11. Edge cases and corner cases
12. State transitions and side effects
13. Verify improvement: Run coverage again, confirm measurable increase

Present new test code blocks only. Follow existing test patterns and naming conventions.
