CTAL-ATT - Certified Tester Advanced Level Agile Technical Tester

The mnemonic FIRST is used to describe good unit tests in Agile software development. Each letter stands for a quality that the tests should possess:

• F - Fast: Tests should run quickly.
• I - Isolated: Tests should not depend on each other.
• R - Repeatable: Tests should yield the same results every time.
• S - Self-Validating: Tests should have a boolean output (pass or fail).
• T - Thorough: Tests should cover every part of the code.

Option D correctly states the meanings of the letters IRST in the context of the FIRST mnemonic.

The epic described is broad and encompasses a system that involves multiple stakeholders and vehicle types, indicating that it is not a small piece of work that can be completed in a short iteration. This violates the ‘Small’ criterion of INVEST, which states that stories should be the smallest piece of work that delivers useful functionality to fit within an iteration12. Additionally, the epic’s acceptance criteria apply to all user stories derived from it, suggesting that the stories are not independent of each other, as changes to one could affect the others. This goes against the ‘Independent’ criterion, which emphasizes that stories should be self-contained to avoid delays caused by dependencies12.

References = The INVEST criteria are a set of guidelines used to evaluate the quality of user stories and epics in Agile development. They ensure that the stories are well-defined and suitable for Agile practices, focusing on creating value through independent, negotiable, valuable, estimable, small, and testable stories123.

After identifying test cases that require refactoring, the next task is to analyze the impact of the current iteration’s functionality on the existing regression tests. This involves assessing how the new changes will affect the tests and determining if the tests still cover the necessary aspects of the software. The goal is to ensure that the regression tests remain relevant and effective in light of the recent changes made to the application.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and related materials emphasize the importance of maintaining the relevance and effectiveness of regression tests throughout the development iterations, which includes analyzing the impact of new functionalities on existing tests12.
