Why Integration Testing Is the Backbone of Reliable Software - Alok - 12-02-2025
Integration testing is a critical layer of quality assurance that ensures software behaves properly when real components work together. Modern applications rarely rely on a single block of code. Instead, they combine routing layers, service logic, business rules, data models, and external integrations. Unit tests can verify each piece independently, but only integration tests confirm that these components interact smoothly and produce the correct results under realistic conditions.
