The Unit Testing Pyramid: Building Quality from the Ground Up
The Unit Testing Pyramid highlights how testing efforts should be distributed for efficient, scalable, and high-quality software delivery. At its base, unit tests form the largest layer because they are quick, isolated, and cost-effective for catching issues early. The middle layer, integration tests, validates how different modules work together, ensuring real-world interactions behave as expected. At the top, UI/end-to-end tests focus on user workflows and overall system behavior, offering high confidence but requiring more time and resources.
This layered approach improves reliability, reduces release risks, and speeds up development cycles. For a deeper breakdown of how to apply the Unit Testing Pyramid in real projects, read the full blog: https://blog.testunity.com/unit-testing-complete-guide/
