The Importance of Layered Software Testing

Effective software testing requires a layered approach rather than relying on a single best practice. Different categories of tests—unit, service-scoped integration, component integration, and end-to-end—each offer unique benefits. This strategy ensures robust coverage, addressing various types of problems and enhancing overall confidence in software quality.

Achieving Software Quality Through Layered Practices

Software quality thrives not on excelling in one area but on maintaining competence across multiple layers of delivery. Each layer acts as a filter, removing around two thirds of defects. Focusing solely on one element, like exhaustive testing, leads to diminishing returns. Collaborative approaches across testing, CI/CD, and requirements prevent issues effectively.
