QUESTION: 16

Which of the following statements about error guessing is true?

Error guessing is a system that adopts artificial intelligence to predict whether software components are likely to contain defects or not
Experienced testers, when applying error guessing, rely on the use of a high-level list of what needs to be tested as a guide to find defects
Error guessing refers to the ability of a system or component to continue normal operation despite the presence of erroneous inputs
Experienced testers, when applying error guessing technique, can anticipate where errors, defects and failures have occurred and target their tests at those issues

Answer(s): D

Explanation:

This answer is correct because error guessing is a test design technique where the experience and intuition of the tester are used to anticipate where errors, defects and failures have occurred or are likely to occur, and to design test cases to expose them. Error guessing can be based on factors such as the complexity of the system or component, the known or suspected weaknesses of the system or component, the previous history of defects, or the common types of errors in the domain or technology. Error guessing can be used as a complementary technique to other more systematic or formal techniques, or when there is insufficient information or time to apply them.

Determining the people who will be involved in the review
Recording the anomalies found during the review meeting
Identifying potential anomalies in the work product under review
Fixing the anomalies found in the work product under review

Answer(s): C

Explanation:

This answer is correct because identifying potential anomalies in the work product under review is one of the tasks the Author is responsible for, as part of a typical formal review. The Author is the person who creates the work product to be reviewed, such as a requirement specification, a design document, or a test case. The Author's tasks include preparing the work product for the review, identifying potential anomalies in the work product, and fixing the anomalies found in the work product after the review.

QUESTION: 18

The whole-team approach:

promotes the idea that all team members should have a thorough understanding of test techniques
is a consensus-based approach that engages the whole team in estimating the user stories
promotes the idea that all team members should be responsible for the quality of the product
is mostly adopted in projects aimed at developing safety-critical systems, as it ensures the highest level of testing independence

Answer(s): C

Explanation:

This answer is correct because the whole-team approach is a way of working in agile projects where all team members share the responsibility for the quality of the product, and collaborate on delivering value to the customer. The whole-team approach involves testers, developers, business analysts, product owners, and other stakeholders in planning, designing, developing, testing, and delivering the product. The whole-team approach fosters communication, feedback, learning, and continuous improvement within the team.

QUESTION: 19

Consider the following user story about the authentication functionality of an e-commerce website:

"As a logged-in user, I want to change my current password with a new one, so that I can make my account safer".
The following are some of the acceptance criteria defined for the user story:
[a] After the logged-in user has successfully changed his password, an email confirming the change must be sent to him
[b] To successfully change the password, the logged-in user must enter the current password, enter a new valid password, and finally confirm by pressing the 'Change Password' button [c] To be valid, the new password entered by the logged-in user is not only required to meet the criteria related to the length and type of characters, but must also be different form the last 5 passwords of that user
[d] A dedicated error message must be presented to the logged-in user when he enters a wrong current password
[e] A dedicated error message must be presented to the logged-in user when he enters the correct current password, but enters an invalid password
Based only on the given information, which of the following ATDD tests is most likely to be written first?

The logged-in user enters a wrong current password and views the dedicated error message
The logged-in user enters the correct current password, enters a valid new password (different from the last 5 passwords), presses the Change Password' button, and finally receives the e-mail confirming that the password has been successfully changed
The logged-in user enters the correct current password, enters an invalid password, and finally views the dedicated error
The logged-in user submits a purchase order containing ten items, selects to pay with a Visa credit card, enters credit card information of a valid card, presses the 'Confirm' button, and finally views the dedicated message confirming that the purchase has been successful

Answer(s): B

Explanation:

ATDD stands for Acceptance Test-Driven Development, which is a collaborative approach to software development and testing, in which the acceptance criteria of a user story are defined and automated as executable tests before the implementation of the software system. ATDD tests are usually written in a Given-When-Then format, which describes the preconditions, the actions, and the expected outcomes of a test scenario. ATDD tests are intended to verify that the software system meets the expectations and the needs of the users and the stakeholders, as well as to provide feedback and guidance for the developers and the testers. Based on the given information, the ATDD test that is most likely to be written first is the one that corresponds to option B, which is:
Given the logged-in user is on the Change Password page When the user enters the correct current password, enters a valid new password (different from the last 5 passwords), and presses the Change Password button Then the user receives an email confirming that the password has been successfully changed
This ATDD test is most likely to be written first, because it covers the main functionality and the happy path of the user story, as well as the most important acceptance criterion [a]. It also verifies that the user can change the password with a valid new password that meets the criteria related to the length, the type of characters, and the history of the passwords, as specified in the acceptance criterion [c]. The other options are not likely to be written first, because they either cover less critical or less frequent scenarios, such as entering a wrong current password [d] or an invalid new password
[e], or they are not related to the user story or the acceptance criteria at all, such as submitting a purchase order [d].

QUESTION: 20

Which of the following is not an example of a typical generic skill required for testing?

Be able to apply test-driven development
Be able to use test management tools and defect tracking tools
Be able to communicate defects and failures to developers as objectively as possible
Possess the necessary social skills that support effective teamwork

Answer(s): A

Explanation:

Test-driven development is not an example of a typical generic skill required for testing, but rather an example of a specific technical skill or a development practice that may or may not be relevant for testing, depending on the context and the objectives of the testing activities. Test-driven development is an approach to software development and testing, in which the developers write automated unit tests before writing the source code, and then refactor the code until the tests pass. Test-driven development can help to improve the quality, the design, and the maintainability of the code, as well as to provide fast feedback and guidance for the developers. However, test-driven development is not a skill that is generally expected or needed for testers, especially for testers who are not involved in unit testing or who do not have access to the source code. The other options are examples of typical generic skills required for testing, which are skills that are applicable and beneficial for testing in any context or situation, regardless of the specific testing techniques, tools, or methods used. The typical generic skills required for testing include:
Be able to use test management tools and defect tracking tools: These are tools that help testers to plan, organize, monitor, and control the testing activities and resources, as well as to record, track, analyze, and resolve the defects detected during testing. These tools can improve the efficiency, the effectiveness, and the communication of the testing process, as well as to provide traceability, metrics, and reports for the testing outcomes.
Be able to communicate defects and failures to developers as objectively as possible: This is a skill that involves the ability to report and describe the defects and failures found during testing in a clear, concise, accurate, and unbiased manner, using relevant information, evidence, and terminology, without making assumptions, judgments, or accusations. This skill can facilitate the collaboration, the understanding, and the resolution of the defects and failures between the testers and the developers, as well as to prevent conflicts, misunderstandings, or blame games. Possess the necessary social skills that support effective teamwork: These are skills that involve the ability to interact, cooperate, and coordinate with other people involved in or affected by the testing activities, such as the test manager, the test team, the project manager, the developers, the customers, the users, etc. These skills can include communication, negotiation, leadership, motivation, feedback, conflict resolution, etc. These skills can enhance the quality, the productivity, and the satisfaction of the testing process, as well as to foster a positive and constructive testing culture.
