#QA Engineering

For me, QA (Quality Assurance) is not just about finding bugs, but about building systems that automatically detect issues before they reach production.

#Methodology

We use a layered testing approach:

  1. Unit Testing: Ensures core logic behaves according to specifications.
  2. Integration Testing: Validates communication between components.
  3. End-to-End (E2E) Testing: Simulates complete user flows from the user interface.

#Infrastructure

Our testing infrastructure is managed in the repository (infrastructure-as-code) to ensure environmental reproducibility.
