Question 1

What is test oracle?

AThe source of lest objectives

BThe source for the actual results

CThe source of expected results

DThe source of input conditions

Answer : C

A test oracle is a mechanism or principle that can be used to determine whether the observed behavior or output of a system under test is correct or not1.A test oracle can be based on various sources of expected results, such as specifications, user expectations, previous versions, comparable systems, etc2.Reference: ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Section 1.2.1, Page 91; ISTQB Glossary of Testing Terms, Version 4.0, Page 332.

Question 2

You are performing the role of tester on an Agile project. Which of the following tasks would be your responsibility?

i. Understanding, implementing, and updating the test strategy.

II . Ensuring the proper use of testing tools.

Hi. Coaching other team members in the relevant aspects of testing.

iv . Actively collaborating with developers and business stakeholders to clarify requirements, especially in terms of testability, consistency, and completeness.

v. Participating proactively in team retrospective meeting, suggesting and implementing improvements.

Select the correct answer:

Ai, iv and v

Bi, ii and iii

Ci, iii and v

Diii . iv and v

Answer : A

In an Agile project, a tester's responsibilities include understanding, implementing, and updating the test strategy (i), actively collaborating with developers and business stakeholders to clarify requirements, especially in terms of testability, consistency, and completeness (iv), and participating proactively in team retrospective meetings, suggesting and implementing improvements (v). These activities ensure that testing is integrated into the development process, promoting continuous feedback and improvement. The ISTQB CTFL syllabus underlines the collaborative nature of Agile testing and the tester's role in contributing to the team's overall quality goals.

Question 3

A company runs a pilot project for evaluation of a test automation tool. Which of the following is NOT a valid object of this pilot project?

AGet familiar with the functionality and options of the tool

BCheck haw the tool fits to the existing test processes

CTrain all testers on using the tool

DDecide upon standards for tool implementation

Answer : C

A pilot project is a small-scale experiment or trial that is conducted to evaluate the feasibility, effectiveness, and suitability of a test automation tool before implementing it on a larger scale1.

The objectives of a pilot project may vary depending on the context and scope of the test automation initiative, but some common ones are2:

To get familiar with the functionality and options of the tool

To check how the tool fits to the existing test processes and environment

To assess the benefits and challenges of using the tool

To decide upon standards and guidelines for tool implementation and usage

To estimate the costs and resources required for tool deployment and maintenance

Therefore, option C is not a valid objective of a pilot project, as it is not necessary to train all testers on using the tool at this stage. Training all testers on using the tool would be more appropriate after the tool has been selected and approved for full-scale implementation, and after the standards and guidelines have been established. Training all testers on using the tool during the pilot project would be inefficient, costly, and premature, as the tool may not be suitable or effective for the intended purpose, or may be replaced by another tool later.

Question 4

Which of the following statements refers to a good testing practice that applies to all software development lifecycles?

AEach test level should have its own specific test objectives that should be consistent with the software development lifecycle phase or type of activities it addresses.

BTest analysis and design for any test levels should begin as soon as coding is complete, and all system components are available for testing

CThe most efficient and effective method of conveying information to and within a development team is face-to-face conversation.

DAll the tests should be automated and run as part of the continuous integration process with every software change

Answer : A

Good testing practice dictates that each test level (e.g., unit testing, integration testing, system testing) should have distinct test objectives aligned with the phase of the software development lifecycle it addresses. This ensures that testing is effective and relevant at each stage. According to the ISTQB CTFL Syllabus v4.0, establishing clear test objectives that are consistent with the development phase helps in achieving specific goals and improving the overall quality of the software product.

Question 5

Which of the following statements about retrospectives is TRUE?

AOnly developers and testers should be involved in retrospectives, as involving people in other roles is very likely to prevent developers and testers from having open and constructive discussions that really help identify process improvements.

BRetrospectives can be very effective in identifying process improvements and can also be very efficient and cost-effective especially since, unlike reviews, they do not require any follow-up activities

COn Agile projects, well-conducted retrospectives at the end of each iteration can help the team reduce and sometimes even eliminate the need for dairy stand-up meetings.

DDuring retrospectives, in addition to identifying relevant process improvements, participants should also consider how to implement these improvements and retain them based on the context of the project, such as the software development lifecycle.

Answer : D

Retrospectives are a crucial part of Agile practices, aiming to identify process improvements and determine how to implement them effectively. They should involve participants discussing not only what improvements could be made but also how to integrate and sustain those improvements within the project context, including the software development lifecycle. This makes statement D accurate according to the ISTQB CTFL syllabus.

Question 6

Which of the following statements about estimation of the test effort is WRONG?

AOnce the test effort is estimated, resources can be identified and a schedule can be drawn up.

BEffort estimate can be inaccurate because the quality of the product under tests is not known.

CEffort estimate depends on the budget of the project.

DExperience based estimation is one of the estimation techniques.

Answer : C

Effort estimate does not depend on the budget of the project, but rather on the scope, complexity, and quality of the software product and the testing activities1. Budget is a constraint that may affect the feasibility and accuracy of the effort estimate, but it is not a factor that determines the effort estimate.Effort estimate is the amount of work required to complete the testing activities, measured in terms of person-hours, person-days, or person-months2.

The other options are correct because:

A .Once the test effort is estimated, resources can be identified and a schedule can be drawn up, as they are interrelated aspects of the test planning process3.Resources are the people, tools, equipment, and facilities needed to perform the testing activities4.Schedule is the time frame and sequence of the testing activities, aligned with the project milestones and deadlines5.

B .Effort estimate can be inaccurate because the quality of the product under tests is not known, as it affects the number and severity of the defects that may be found and the rework that may be needed to fix them6.Quality is the degree to which the software product satisfies the specified requirements and meets the needs and expectations of the users and clients7.

D . Experience based estimation is one of the estimation techniques, which relies on the judgment and expertise of the testers and other project stakeholders to estimate the test effort based on similar projects or tasks done in the past. Experience based estimation can be useful when there is a lack of historical data, formal methods, or detailed information about the software product and the testing activities.
