Front-End Testing

Front end testing strategies
  1. Unit tests: Unit testing is a fundamental software testing method. It examines each module and function and ensures its performance. Here, developers use pre-defined inputs to see whether they get the expected outputs.
  2. Integration tests: Most modern apps use numerous modules. Developers integrate these modules to provide the best results. Integration testing verifies that these integrations are effective.
  3. End-to-end (E2E) testing: The developer tests the whole application from start to end. Testers mimic an actual user’s actions within real-world scenarios to guarantee seamless communication for the users.
