Why Frontend Testing Matters

Testing helps keep your frontend code solid by catching bugs, edge cases, and weird scenarios early. It makes your code cleaner, your changes safer, and even doubles as handy documentation.

Unit Testing

Tests small individual parts (units) of the application in isolation.

Functions (utility, helpers)
Classes (business logic, services)
Small components

Integration Testing

Tests how multiple units work together when combined.

Data flow between components
Component and API interaction
Form validation

End-to-End Testing

Simulates real user flow across the full system from start to finish.

User workflows (login, checkout)
Critical features and paths
Cross-browser/device testing
