Benefits of Testing Quadrants
1. Introduction
In agile testing, it is important for both technical and non-technical stakeholders to understand why different types of tests exist and what their purposes are.
The testing quadrants model is a simple but powerful way to visualize and communicate this information.
애자일 테스트에서는 기술적·비기술적 이해관계자 모두가 테스트 유형의 차이와 목적을 이해하는 것이 중요합니다.
테스팅 사분면(Testing quadrants)은 이를 쉽게 설명하기 위한 모델입니다.
2. Practice Question
❓ Question
How can the testing quadrants be beneficial for testing?
- a) They help in test planning by dividing the test process into four phases, corresponding to the four basic test levels
- b) They help in assessing high-level coverage based on low-level coverage
- c) They help non-technical stakeholders understand different test types and that some test types are more relevant to certain test levels than others
- d) They help agile teams develop a communication strategy based on psychological types
✅ Correct Answer: c)
3. Explanation
✔ c) Helping stakeholders understand test types — Correct
The testing quadrants classify tests along two dimensions:
- Business-facing vs. Technology-facing
- Supporting the team vs. Critiquing the product
This helps managers, testers, developers, and other stakeholders:
- Understand why multiple test types are needed
- See that not all tests are the same or serve the same purpose
- Recognize that some test types are more relevant at certain times or levels
As a result, the testing quadrants act as a communication and understanding tool, especially for non-technical stakeholders.
테스팅 사분면은 테스트를 관점(비즈니스/기술)과 목적(팀 지원/제품 평가) 기준으로 분류합니다.
이를 통해 비기술적 이해관계자도 테스트 유형 간의 차이와 역할을 쉽게 이해할 수 있습니다.
❌ a) Dividing testing into four test levels — Incorrect
Testing quadrants are not related to test levels (component, integration, system, acceptance).
They classify test types, not phases or levels.
테스팅 사분면은 테스트 레벨을 설명하는 모델이 아닙니다.
❌ b) Assessing coverage — Incorrect
Testing quadrants do not provide any coverage metrics or mechanisms for mapping low-level to high-level coverage.
사분면은 커버리지를 계산하거나 평가하는 도구가 아닙니다.
❌ d) Psychological communication model — Incorrect
Testing quadrants have nothing to do with psychology or classifying people.
They focus purely on test types and purposes.
테스팅 사분면은 심리학 모델이 아닙니다.
4. Summary Table
| Option | Claim | Correct? | 이유 |
|---|---|---|---|
| a | Defines test levels | ✖ No | 레벨 아님 |
| b | Helps assess coverage | ✖ No | 커버리지 무관 |
| c | Explains test types to stakeholders | ✔ Yes | 정답 |
| d | Psychological model | ✖ No | 관련 없음 |
5. Final Takeaway
For the ISTQB exam, remember:
Testing quadrants are a communication tool that help stakeholders understand different test types, their purposes, and their viewpoints.
시험 대비 핵심 문장입니다.
테스팅 사분면은 다양한 테스트 유형과 목적을 이해관계자에게 쉽게 설명하기 위한 커뮤니케이션 도구이다.
