Answer: C
Explanation:
Explanation
Agile Teams are responsible for ensuring quality is built into the code in SAFe. SAFe is a framework for scaling agile practices across the enterprise, based on the principles of Lean, Agile, and DevOps. SAFe organizes the enterprise into Agile Release Trains (ARTs), which are teams of Agile Teams that deliver value in a regular cadence. Agile Teams are the fundamental building blocks of SAFe, and they are cross-functional, self-organizing, and self-managing teams that deliver value in short iterations. Agile Teams are responsible for ensuring quality is built into the code in SAFe, by applying the following practices:
Test-first - Test-first is a practice that involves writing tests before writing code, to ensure that the code meets the requirements and standards, and does not introduce any defects or vulnerabilities. Test-first helps to improve the design and maintainability of the code, and to accelerate the feedback and validation process. Test-first can be implemented using various techniques, such as Test-Driven Development (TDD), Behavior-Driven Development (BDD), or Acceptance Test-Driven Development (ATDD).
Built-in quality - Built-in quality is a practice that involves applying quality standards and checks throughout the solution lifecycle, rather than inspecting quality after the fact. Built-in quality helps to prevent defects from escaping to downstream stages or customers, and to reduce the cost and risk of rework and waste. Built-in quality can be achieved using various methods, such as code quality and security analysis, code review, pair programming, refactoring, and continuous testing.
Continuous testing - Continuous testing is a practice that involves automating and executing tests at every stage of the Continuous Delivery Pipeline, to verify that the solution meets the functional and nonfunctional requirements and standards, and to detect and resolve any issues or defects as early as possible. Continuous testing helps to ensure the reliability and performance of the solution, and to support the delivery and deployment of value to the customer. Continuous testing can be performed using various tools and frameworks, such as unit testing, integration testing, system testing, acceptance testing, performance testing, and security testing
