FAQPage Schema

How do I identify untested edge cases in my code?▼

Edge cases are code paths and input combinations not covered by existing tests. Systematic analysis of your module's inputs, internal state, dependencies, and current test coverage reveals gaps where bugs hide. BugMagnet automates this discovery by examining your implementation and tests together to surface reliability gaps.

Can I use edge case testing across different programming languages?▼

Yes. Edge case analysis works across languages because it focuses on logic paths, input boundaries, and state transitions—concepts that transcend syntax. BugMagnet detects your language from file extensions and project structure, then applies language-appropriate testing conventions to your codebase.

What's the workflow for finding and fixing test coverage gaps?▼

Read your implementation and tests, detect language and testing conventions, locate existing tests, evaluate what paths are uncovered, generate candidate tests for edge cases, and iterate to fix gaps. BugMagnet performs this systematic analysis end-to-end, producing actionable recommendations with suggested fixes.

How do I know which edge cases matter most for my module's public API?▼

Prioritize edge cases by analyzing your module's public APIs—the inputs, outputs, and state transitions users will actually exercise. BugMagnet examines public API contracts alongside internal state and dependencies to identify which gaps pose the highest reliability risk.

Do I need specific testing frameworks for edge case coverage analysis?▼

No. Edge case analysis is framework-agnostic; it works with any testing convention your language supports. BugMagnet detects your testing setup from project structure and applies appropriate conventions, so you work with what you already have.
