Automated testing in DevSecOps is a crucial practice that ensures the continuous validation of code changes for security and functionality

It is a key part of DevSecOps. It is enabled by multiple tools that measure both test code coverage and test results. They are fully automated and do not require human action. It also enables new concepts like pair programming and peer code review.

Agile brings several new models for creating the right tests:

Test-driven development (TDD) is a software development process that relies on very short development cycles: requirements are turned into very specific test cases first, then the software is built to pass the tests.

Acceptance test–driven development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers.

ATDD encompasses many of the same practices as specification by example, behavior-driven development (BDD), example-driven development (EDD), and support-driven development also called story test–driven development (SDD).

All these processes aid developers and testers in understanding the customer’s needs prior to implementation and allow customers to be able to converse in their own domain language.
