Expand Unit Tests

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

Workflow

1. Analyze Coverage

Run coverage report to identify:

• Untested branches
• Edge cases
• Low-coverage areas

2. Identify Gaps

Review code for:

• Logical branches
• Error paths
• Boundary conditions
• Null/empty inputs

3. Write Tests

Use project's framework:

• JavaScript/TypeScript: Jest, Vitest, Mocha
• Python: pytest, unittest
• Go: testing, testify
• Rust: built-in test framework

4. Target Specific Scenarios

• Error handling and exceptions
• Boundary values (min/max, empty, null)
• Edge cases and corner cases
• State transitions and side effects

5. Verify Improvement

Run coverage again, confirm measurable increase.

Guidelines

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