NEW QUESTION 45
Is it a good idea to follow each automated build with the execution of automated tests?
- A. Yes, it will show code coverage which is an excellent metric of quality and progress
- B. No, it takes too much time
- C. Yes, the tests may identify whether there are bugs that the developers should fix before proceeding
- D. No, the outcomes might disturb the developers' focus
Answer: C
Explanation:
It's definitely a good practice. And not because you can see the code coverage (which also isn't an excellent metric of quality and progress), but because you can detect problems before moving on.
NEW QUESTION 46

- C. Demonstrating code is well structured and cleanly implemented
- D. Determining the number of unit tests required to ensure correctness
Answer: A
Explanation:
Cyclomatic complexity is a number expressing the number of different paths that can be taken throughout the code. Higher means complex code.

NEW QUESTION 57
The practice of decomposing a requirement into failing tests is called:
- A. Scrum testing
- B. Regression testing
- C. Behavior driven development
- D. Acceptance test driven development
Answer: D
Explanation:
In ATDD you start with writing tests to represent the requirement. Since you start with this, there is no production code to satisfy the test which is why the tests will fail.
NEW QUESTION 58
What are some disadvantages of code coverage as a measure for how well a system or product is tested? (three answers)
- A. It does not ensure that the most important or highest risk areas of the code are being exercised by tests
- B. It only provides insights to programmers
- C. It is too complicated to explain to management
- D. It could create incentives to write tests that simply increase code coverage, rather than tests that find bugs without increasing code coverage
- E. It does not measure usability
Answer: A,D,E
Explanation:
Not being able to explain to management should never be the reason to not do it. It doesn't only provide some data to programmers, the problem is that code coverage alone is not meaning a lot.
