Chapter 3 - Quiz

Question 1

Which of the following statements about static testing are MOST true?

Answer 1

Static testing is a cheap way to detect and remove defects

Question 2

Which of the following statements CORRECTLY reflects the value of static testing?

Answer 2

Since we started using static analysis, we find coding defects that might have not been found by performing only dynamic testing

Question 3

Question #3.1.05

You are working on a video game development project, using Agile methods. It is based on Greek mythology and history, and players can play key roles in scenarios such as the battles between the Greeks and Trojans.

Consider the following user story and its associated acceptance criteria:

As a player, I want to be able to acquire the Rod of Midas (a new magic object), so that I can turn objects and other players into gold

AC1: The Rod must work on any object or player, no matter what size, which can be touched anywhere by the player holding the Rod

AC2: Holding the Rod does not change the player holding it into gold

AC3: Any object or player touched by the Rod transforms completely into gold within one millisecond

AC4: The Rod appears as shown in Prototype O.W.RoM

AC5: The transformation starts at the point of contact with the Rod and moves at a rate of one meter per millisecond

You are participating in a checklist-based review session of this user story.

This user story and its associated acceptance criteria contain which of the following typical defects identified by static testing in this type of work product?

Answer 3

Contradiction
Contradiction is a typical requirements defect. AC3 and AC5 conflict if the Rod is touched to an object that extends more than 1 meter in any direction from the point at which touched, since AC1 does not limit the size of the objects to be touched

Question 4

Which testing technique would be most effective in determining and improving the maintainability of the code (assuming developers fix what is found)?

Answer 4

Static aanalysis
Static analysis with tools will give the best results for improving maintainability and ensuring adherence to good coding practices.

Question 5

Which of the following is a benefit of static analysis?

Answer 5

Defects can be identified that might not be caught by dynamic testing

Static analysis with a static analyzer can be used to find defects such as uninitialized variables that could be difficult to catch with dynamic testing.

Question 6

Which of the following statements about static testing is False?

Answer 6

Static analysis is applicable to executing test scripts

Question 7

Question #3.1.11

Which of the following statements are characteristics of static testing, and which are characteristics of dynamic testing?

1. Finds defects in work products directly.
2. Better for ensuring internal quality (e.g. standards are followed).
3. Finds defects through failures in execution.
4. Easier and cheaper to find and fix security vulnerabilities (e.g. buffer overflow).
5. Focuses on externally visible behaviours.

Answer 7

Static testing = 1, 2, 4

Dynamic testing = 3, 5

Question 8

Which of the following statements BEST states the value of static testing

Question 23

Question #3.2.04

You will be invited to a review. The work product to be reviewed is a description of the in-house document creation process. The aim of the description is to present the work distribution between the different roles involved in the process in a way that can be clearly understood by everyone. You will be invited to a checklist-based review. The checklist will also be sent to you. It includes the following points:

i. Is the person who performs the activity clearly identified for each activity?
ii. Are the entry criteria clearly defined for each activity?
iii. Are the exit criteria clearly defined for each activity?
iv. Are the supporting roles and their scope of work clearly defined for each activity?

In the following we show an excerpt of the work result to be reviewed, for which you should use the

checklist above:

“After checking the customer documentation for completeness and correctness, the software architect creates the system specification. Once the software architect has completed the system specification, he invites testers and verifiers to the review. A checklist describes the scope of the review. Each invited reviewer creates review comments - if necessary - and concludes the review with an official review done-comment.”

Which of the following statements about your review is correct?

Answer 23

Point i -> of the checklist has been violated because it is not clear who is providing the checklist for the invitation to the review
