1. Introduction
A core ISTQB principle states that every development activity should have a corresponding test activity. This applies regardless of the SDLC model in use. This question examines which SDLC models follow this rule.
ISTQB에서는 “각 개발 활동에는 대응되는 테스트 활동이 있다”고 설명합니다. 이 규칙이 어떤 SDLC 모델에서 적용되는지를 묻는 문제입니다.2. Sample Question
Consider the following rule: “for every SDLC activity there is a corresponding test activity”. In which SDLC models does this rule hold?
- a) Only in sequential development models
- b) Only in iterative development models
- c) Only in iterative and incremental development models
- d) In sequential, incremental, and iterative development models
3. Correct Answer
✔ Correct Answer: d)
This rule holds for all SDLC models — sequential, incremental, and iterative. Testing must be aligned with development activities regardless of the chosen lifecycle.
정답은 d)입니다. 이 규칙은 모든 SDLC 모델(순차적, 점증적, 반복적)에 적용됩니다.4. Why the Other Options Are Not Correct
a) Only in sequential development models — ✖ Not correct
Even in non-sequential models like Agile, testing activities correspond to development activities. Therefore, this option is too limited.
순차적 모델뿐 아니라 다른 SDLC에서도 동일 규칙이 적용되므로 틀렸습니다.b) Only in iterative development models — ✖ Not correct
Iterative models do follow the rule, but they are not the only ones. Sequential and incremental models also apply it.
반복 모델에서도 적용되지만, 반복 모델만 적용되는 것은 아니므로 틀렸습니다.c) Only in iterative and incremental models — ✖ Not correct
This excludes sequential models, which also follow the rule. Thus, the option is incomplete.
순차 모델에도 적용되므로 “반복 + 점증 모델만”이라는 표현은 틀렸습니다.d) In sequential, incremental, and iterative development models — ✔ Correct
This option includes all major SDLC models. Testing activities always correspond to development activities independent of lifecycle structure.
모든 SDLC 모델에 적용되므로 정답입니다.5. Summary
The principle that every development activity has a corresponding test activity is universal. It applies to sequential, incremental, and iterative models alike, ensuring testing remains aligned with development throughout the lifecycle. FL-2.1.2
이 규칙은 모든 SDLC에 공통적으로 적용되며, 개발과 테스트는 항상 대응 관계를 유지해야 합니다.Related: More ISTQB posts | 다음 문제
