ISTQB 4.0 - Sample Exam Reviewer Flashcards
Chapter 1
Which of the following ststements describe a valid test objective?
a. To prove that there are no unfixed defects in the system under test
b. To prove that there will be no failures after the implementation of the system into production
c. To reduce the risk level of the test object and to build confidence in the quality level
d. To verify that there are no untested combinatoin of inputs
c. To reduce the risk level of the test object and to build confidence in the quality level
Choice C is correct. Testing finds defects and failures which reduces the level of risk and at the same time gives more confidence in the quality level of the test object.
Choice A is not correct. It is impossible to prove that there are no defects anymore in the system under test. See testing principle
Choice B is not correct. See testing principle 7 - Absence-of-defects fallacy
Choice D is not correct. It is impossible to test all combinations of inputs
Chapter 1
Which of the following options shows an example of test activities that contribute to success?
a. Having testers involved during various software development lifecycle (SDLC) activities will help to detect defects in work products
b. Testers try not to disturb the developers while coding, so that the developers write better code
c. Testers collaborating with end users help to improve the quality of defect reports during component integration and system testing
d. Certified testers will design much better test cases than non-certified testers
a. Having testers involved during various software development lifecycle (SDLC) activities will help to detect defects in work products
Choice A is correct. It is important that testers are involved from the beginning of the software development lifecycle (SDLC). It will increase understanding of design decisions and will detect defects early.
Choice B is not correct. Both developers and testers will have more understanding of each other’s work products and how to test the code.
Choice C is not correct. End users will not help the testers in increasing the quality of defect reports; also, users usually do not participate in low-level testing levels like integration testing
Choice D is not correct. Being certified does not automatically mean that the tester will be better in test design
Chapter 1
You have been assigned as a tester to a team producing a new system incrementally. You have noticed that no changes have been made to the existing regression test cases for several iterations and no new regression defects were identified. Your manager is happy, but you are not. Which testing principle explains your skepticism?
a. Tests wear out
b. Absence-of-errors fallacy
c. Defects cluster together
d. Exhaustive testing is impossible
A. Test wears out
Choice A is correct. This principle means that if the same tests are repeated over and over again, eventually these tests no longer find any new defects. This is probably why the tests all passed in this release as well.
Choice B is not correct. This principle says about the mistaken belief that just finding and fixing a large number of defects will ensure the success of a system
Choice C is not correct. This principle says that a small number of components usually contain most of the defects
Choice D is not correct. This principle states that testing all combinations of inputs and preconditions is not feasible
Chapter 1
You work in a team that develops a mobile application for food ordering. In the current iteration the team decided to implement the payment functionality.
Which of the following activities is a part of test analysis?
a. Estimating that testing the integration with the payment service will take 8 person-days
b. Deciding that the team should test if it is possible to properly share payment between many users
c. Using boundary value analysis (BVA) to derive the test data for the test cases that check the correct payment processing for the minimum allowed amount to be paid
d. Analyzing the discrepancy between the actual result and expected result after executing a test case that checks the process of payment with a credit card, and reporting a defect
b. Deciding that the team should test if it is possible to properly share payment between many users
Choice B is correct. This is an example of defining test conditions which is a part of test analysis
Choice A is not correct. Estimating the test effort is part of test planning
Choice C is not correct. Using test techniques to derive coverage items is a part of test design
Choice D is not correct. Reporting defects found during dynamic testing is a part of test execution
Chapter 1
Which of the following factors have a SIGNIFICANT influence on the test approach?
i. The SDLC
ii. The number of defects detected in previous projects
iii. The identified product risks
iv. New regulatory requirements forcing formal white-box testing
v. The test environment setup
a) i, ii have significant influence
b) i, iii, iv have significant influence
c) ii, iv, v have significant influence
d) iii, v have significant influence
b. i, iii, iv
i is true. The SDLC has an impact on the test approach
ii is false. The number of defects detected in previous projects may have some influence, but this is not as significant as i, iii, and iv.
iii is true. The identified product risks are one of the most important factors influencing the test approach
iv is true. Regulatory requirements are important factors influencing the test approach
v is false. The test environment has no significant influence on the test approach
Chapter 1
Which TWO of the following tasks belong MAINLY to a testing role?
a) Configure test environments
b) Maintain the product backlog
c) Design solutions to new requirements
d) Create the test plan
e) Analyze the test basis
Select TWO options.
a. Configure test environments
e. Analyze the test basis
Choice A is correct. This is done by testers
Choice B is not correct. The product backlog is built and maintained by the product owner.
Choice C is not correct. This is done by the development team.
Choice D is not correct. This is a managerial role.
Choice E is correct. This is done by the testers since its technical task done as part of a test analysis.
Chapter 1
Which of the following skills (i-v) are the MOST important skills of a tester?
i. Having domain knowledge
ii. Creating a product vision
iii. Being a good team player
iv. Planning and organizing the work of the team
v. Critical thinking
a) ii and iv are important
b) i, iii and v are important
c) i, ii and v are important
d) iii and iv are important
b. i, iii, and v are important
i is true. Having domain knowledge is an important tester skill
ii is false. This is a task of the business analyst together with the business representative
iii is true. Being a good team player is an important skill
iv is false. Planning and organizing the work of the team is a task of the test manager or, mostly in an Agile software development project, the whole team and not just the tester
v is true. Critical thinking is one of the most important skills of testers

c) In ATDD, tests are created, based on acceptance criteria to drive the development of the
related software
d) in ATDD, tests are based on the desired behavior of the software, which makes it easier for
team members to understand them
Select ONE option.
c) In ATDD, tests are created, based on acceptance criteria to drive the development of the
related software
Choice C is correct. In acceptance test-driven development (ATDD) tests are written from acceptance criteria as part of the design process
Choice A is not correct. It is more often used in behaviour-driven development (BDD)
