Integration Testing Is the Backbone of Reliable Software - Alok - 12-02-2025
The strength of integration testing lies in its ability to reveal functional mismatches that are otherwise easy to miss. A function may work correctly on its own, but fail when real data flows through multiple layers of the system. For example, an API endpoint might expect a field that is not returned by the database, or a validation rule may only fail when combined with another process. Integration tests uncover these issues early so that they do not appear during deployment or user interaction.
