ISTQB CTFL Mock Exams

Which of the following statements describe a valid test objective?

• To prove that there are no unfixed defects in the system under test
• To prove that there will be no failures after the implementation of the system into production
• To reduce the risk level of the test object and to build confidence in the quality level
• To verify that there are no untested combinations of inputs

Answer explanation

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

Which of the following options shows an example of test activities that contribute to success?

• Having testers involved during various software development lifecycle (SDLC) activities will help to detect defects in work products
• Testers try not to disturb the developers while coding, so that the developers write better code
• Testers collaborating with end users help to improve the quality of defect reports during component integration and system testing
• Certified testers will design much better test cases than non-certified testers

Answer explanation

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.

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?

• Tests wear out
• Absence-of-errors fallacy
• Defects cluster together
• Exhaustive testing is impossible

Answer explanation

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 wel

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?

• Estimating that testing the integration with the payment service will take 8 person-days
• Deciding that the team should test if it is possible to properly share payment between many users
• 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
• 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

Answer explanation

This is an example of defining test conditions which is a part of test analysis

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

• i, ii have significant influence
• i, iii, iv have significant influence
• ii, iv, v have significant influence
• iii, v have significant influence

Answer explanation

i. Is true. The SDLC has an influence 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 Thus: a) Is not correct b) Is correct c) Is not correct d) Is not correct

Which TWO of the following tasks belong MAINLY to a testing role?

• Configure test environments

• Maintain the product backlog
• Design solutions to new requirements
• Create the test plan
• Analyze the test basis

Answer explanation

a) Is correct. This is done by the testers

b) Is not correct. The product backlog is built and maintained by the product owner

c) Is not correct. This is done by the development team

d) Is not correct. This is a managerial role

e) Is correct. This is done by the testers since its technical task done as part of a test analysis.

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

• ii and iv are important
• i, iii and v are important
• i, ii and v are important
• iii and iv are important

Answer explanation

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 Thus: a) Is not correct b) Is correct c) Is not correct d) Is not correct

How is the whole team approach present in the interactions between testers and business representatives?

• Business representatives decide on test automation approaches
• Testers help business representatives to define test strategy
• Business representatives are not part of the whole team approach
• Testers help business representatives to create suitable acceptance tests

Answer explanation

Testers will work closely with business representatives to ensure that the desired quality levels are achieved. This includes supporting and collaborating with them to help them create suitable acceptance tests

Consider the following rule: “for every SDLC activity there is a corresponding test activity”. In which SDLC models does this rule hold?

• Only in sequential SDLC models
• Only in iterative SDLC models
• Only in iterative and incremental SDLC models
• In sequential, incremental, and iterative SDLC models

Answer explanation

This rule holds for all SDLC models

Which of the following statements BEST describes the acceptance test-driven development (ATDD) approach?

• In ATDD, acceptance criteria are typically created based on the given/when/then format
• In ATDD, test cases are mainly created at component testing and are code-oriented
• In ATDD, tests are created, based on acceptance criteria to drive the development of the related software
• in ATDD, tests are based on the desired behavior of the software, which makes it easier for team members to understand them

Answer explanation

In acceptance test-driven development (ATDD) tests are written from acceptance criteria as part of the design process
