質問 # 52
You are working on an Agile project and have been asked to implement exploratory testing for the current sprint. Which one of the following is a correct approach to adopt?

A. Ask experienced testers to try and find new defects by using the system without the constraint of documentation and tools.
B. Allocate independent testers to design exploratory tests using test charters in time boxed sessions. Plan to run all sessions in parallel with each session lasting more than 5hours.
C. Ask experienced testers to prepare test charters for time boxed sessions lasting no more than 2hours.Tests should be designed and executed within each session using heuristics, creativity and intuition.
D. Use testers who have not been involved in the sprint to write new test cases from the user stories. These test cases are then executed in a time boxed session for the sprint.

正解：C

解説：
Exploratory testing is a testing approach that emphasizes learning, creativity, and adaptability. It involves simultaneous test design and test execution, where the tester uses heuristics, intuition, and experience to explore the system under test and discover new information12. Exploratory testing can be performed in an Agile project to complement other testing activities, such as test-driven development, behavior-driven development, and acceptance test-driven development12.
The correct approach to adopt for exploratory testing in an Agile project is D, as it follows the best practices for exploratory testing1234:
* Ask experienced testers to prepare test charters for time boxed sessions lasting no more than 2 hours: A test charter is a brief document that describes the scope, objective, and strategy of an exploratory testing session. A test charter helps to guide the tester's exploration and to document the results. A time box is a fixed period of time allocated for an exploratory testing session. A time box helps to focus the tester's attention and to limit the scope of exploration. A time box should not be too long, as it may reduce the tester's concentration and creativity. A recommended duration for a time box is between 45 minutes and 2 hours.
* Tests should be designed and executed within each session using heuristics, creativity and intuition:
Exploratory testing is an iterative and interactive process, where the tester designs and executes tests based on the observations and feedback from the system under test. The tester uses heuristics, which are rules of thumb or shortcuts that help to simplify the testing problem and to generate test ideas. The tester also uses creativity and intuition, which are mental abilities that help to generate novel and useful solutions and to make judgments based on incomplete or uncertain information.
The incorrect approaches to adopt for exploratory testing in an Agile project are A, B, and C, as they violate the principles and practices of exploratory testing1234:
* A: Allocate independent testers to design exploratory tests using test charters in time boxed sessions.
Plan to run all sessions in parallel with each session lasting more than 5 hours: This approach is incorrect because it does not involve simultaneous test design and test execution, which is the essence of exploratory testing. It also uses too long time boxes, which may reduce the tester's concentration and creativity. It also does not leverage the collaboration and communication within the Agile team, as it isolates the testers from the developers and other stakeholders.
* B: Ask experienced testers to try and find new defects by using the system without the constraint of documentation and tools: This approach is incorrect because it does not use test charters, which are essential for guiding and documenting the exploratory testing sessions. It also does not use heuristics, creativity, and intuition, which are important for generating test ideas and making decisions. It also implies that exploratory testing is an unstructured and random activity, which is a common misconception. Exploratory testing is a disciplined and systematic approach that requires planning, analysis, and evaluation.
* C: Use testers who have not been involved in the sprint to write new test cases from the user stories.
These test cases are then executed in a time boxed session for the sprint: This approach is incorrect because it does not involve simultaneous test design and test execution, which is the essence of exploratory testing. It also uses testers who have not been involved in the sprint, which may reduce their understanding of the system under test and the customer needs. It also does not use test charters, which are essential for guiding and documenting the exploratory testing sessions. It also does not use heuristics, creativity, and intuition, which are important for generating test ideas and making decisions.

質問 # 53
Which of the following activities would you expect most likely to be performed during daily stand-up meetings?

A. Highlighting blocking issues that are impeding the test progress
B. Identifying specific quality risks associated with the next iteration
C. Discussing what did not work well during the previous iteration
D. Creating acceptance tests for the user stories selected for the current iteration

正解：A

解説：
Comprehensive and Detailed Explanation From Exact Extract:
FromCTFL-AT Syllabus v4.0, Section 5.2Daily Stand-Ups, it states:
"The daily stand-up is a short meeting used to discuss progress, plans for the day, and any impediments that are blocking progress." Therefore,Option Bis correct - highlightingimpediments/blockersis a key goal of thedaily stand-up.
* Option Ais aretrospectiveactivity.
* Option Cis done duringplanning or risk assessment, not the daily meeting.
* Option Dis part ofiteration planning, not the stand-up.
References:
CTFL-AT Syllabus v4.0, Section 5.2
Learning Objective (K1) - Recall daily stand-up purpose and format

質問 # 54
Which of the following is the best example of a testable acceptance criterion for test-related activities?

A. The application shall calculate the volume of the solid shapes (cones, pyramids) with reasonable accuracy
B. 100% of the source code must be statically analyzed against some of the known major security vulnerabilities and no errors/warnings must be reported
C. The web application shall provide a response time lower than one second for 95% of the webpages when 100 concurrent users are working on it
D. The application's user interface for the checkout process shall be clear and intuitive to the users

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
FromCTFL-AT Syllabus v4.0, Section 2.1:
"Acceptance criteria should be testable, meaning they should define expected behavior or measurable outcomes that can be verified." Option Ais testable because it includesspecific, measurable conditions: response time, user load, and percentage of pages.
* Option Bis vague aboutwhich vulnerabilitiesandhow errors are defined.
* Option Cusessubjective language("clear and intuitive").
* Option Dis vague about what "reasonable accuracy" means.

Learning Objective (K2) - Identify examples of testable vs. non-testable acceptance criteria

質問 # 55
Which of the following statements would you expect to be the MOST direct advantage of the whole-team approach?

A. Having at least once a day an automated build and test process that detects integration errors early and quickly.
B. Avoiding requirements misunderstandings which may not have been detected until later in the development cycle when they are more expensive to fix.
C. Capitalizing on the combined skills of business representatives, testers and developers working together to contribute to project success.
D. Reducing the involvement of business representatives because of the increased communication and collaboration between testers and developers.

正解：C

解説：
Explanation
The whole-team approach is a principle of agile testing that involves everyone with different knowledge and skills to ensure project success. The whole-team approach means that the business representatives, testers, and developers work together in every step of the development process, from planning to delivery. The whole-team approach aims to enhance communication and collaboration within the team, leverage the various skill sets of the team members, and make quality everyone's responsibility12. Therefore, the statement C is the most direct advantage of the whole-team approach, as it captures the essence of the principle and its benefits.
The other statements are not directly related to the whole-team approach, or are incorrect. Statement A is about continuous integration, which is a practice of agile development that involves having at least once a day an automated build and test process that detects integration errors early and quickly. Continuous integration is not a direct consequence of the whole-team approach, although it may be facilitated by it13. Statement B is about avoiding requirements misunderstandings, which may be a benefit of the whole-team approach, but not the most direct one. The whole-team approach does not only focus on requirements, but also on design, implementation, testing, and delivery. Moreover, avoiding requirements misunderstandings may also depend on other factors, such as the quality of the user stories, the use of acceptance criteria, and the feedback from the customers and users14. Statement D is incorrect, as it contradicts the whole-team approach. The whole-team approach does not reduce the involvement of business representatives, but rather increases it.
Business representatives are an integral part of the whole-team approach, as they provide the vision, the value, and the validation of the product. They collaborate with the testers and developers to define the features, prioritize the backlog, and verify the outcomes12.
