NEW QUESTION 42
A system computes prices for bus tickets. The price depends on
– the passenger type (baby, child, adult, senior citizen, student, military)
– the travelling type (as single or in a group)
– the distance (zone 1. 2. 3)
– the kind of transport (ordinary, express)
Which of the following test techniques is the most appropriate one for testing the price computation?

Statement coverage

State transition testing

Equivalence partitioning

Use case testing

Equivalence partitioning is a technique that divides the input data and output results of a software component into partitions of equivalent data. Each partition should contain data that is treated in the same way by the component. Equivalence partitioning can be used to reduce the number of test cases by selecting one representative value from each partition. Equivalence partitioning is suitable for testing the price computation, as it can identify different partitions based on the passenger type, the travelling type, the distance and the kind of transport. Equivalence partitioning is not statement coverage, which is a technique that measures how many executable statements in a source code are executed by a test suite. Statement coverage is not appropriate for testing the price computation, as it does not consider the input data or output results. Equivalence partitioning is not state transition testing, which is a technique that models how a system transitions from one state to another depending on events or conditions. State transition testing is not relevant for testing the price computation, as it does not involve any states or transitions. Equivalence partitioning is not use case testing, which is a technique that tests how users interact with a system to achieve a specific goal. Use case testing is not applicable for testing the price computation, as it does not focus on a single function or component.

NEW QUESTION 43
Software was found lo take much more time than the stated requirement of less than one second to save a file. Upon investigation it was found that there was an unnecessary check inside a loop which was slowing down the file-save operation. The software not being able to meet the desired response time is an example of

It is not a defect

Defect

Error

Failure

A failure is an event in which a component or system does not perform a required function within specified limits. A failure is observable by the software users or other stakeholders. A failure is caused by one or more defects in the software. In this case, the software not being able to meet the desired response time is an example of a failure, as it deviates from the stated requirement and affects the user experience. It is not a defect, which is a flaw in the software that causes the failure. It is not an error, which is a human action that produces an incorrect result. It is not a non-defect, as it clearly violates a specified requirement. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer], Chapter 1, page 4.

NEW QUESTION 44
Which of the following statements contradicts the general principles of testing?

Most defects are found in a small subset of a system’s modules.

If new defects are to be found we should run the same test set more often.

Testing is better if it starts at the beginning of a project.

How testing is done, is based on the situation in a particular project.

Statement B contradicts the general principles of testing, because running the same test set more often will not increase the chances of finding new defects, unless there are some changes in the system or environment that affect the test results. Running different test sets with different inputs, outputs or conditions would be more effective in finding new defects. Statements A, C and D are consistent with the general principles of testing. Statement A states that most defects are found in a small subset of a system’s modules, which is true according to the defect clustering principle. Statement C states that testing is better if it starts at the beginning of a project, which is true according to the early testing principle. Statement D states that how testing is done, is based on the situation in a particular project, which is true according to the context-dependent testing principle.

NEW QUESTION 45
A test engineer finds a defect while testing. After the developer has fixed the defect, the test engineer decides to re-run a complete section of the tests. Which of the following is correct?

The lest engineer should not re-run the tests, as they have already been run, and results recorded.

The test engineer should not re-run the tests, they should be part of the developer tests.

The test engineer should re-run the tests, in order to ensure that new defects have not been introduced by the fix.

The test engineer should re-run the tests, because the defect shows that the test cases need to be updated.

The test engineer should re-run the tests, in order to ensure that new defects have not been introduced by the fix. This is also known as regression testing, which is a type of testing that verifies that previously tested software still performs correctly after a change. Regression testing helps to detect any side effects or unintended consequences of a fix or a modification. The other options are incorrect reasons for re-running the tests. The test engineer should not re-run the tests, as they have already been run, and results recorded, because this ignores the possibility of new defects caused by the fix. The test engineer should not re-run the tests, they should be part of the developer tests, because this assumes that developer tests are sufficient and reliable, which may not be true. The test engineer should not re-run the tests, because the defect shows that the test cases need to be updated, because this does not address the impact of the fix on other test cases or functionalities.

NEW QUESTION 46
Which of the following statements about test reports are TRUE?
I Test reports shall be approved by the test team.
II Test reports shall give stakeholders information as basis for decisions.
Ill Test reports shall summarize what happened through a period of testing.
IV Test reports shall be approved by the development team, the test team and the customer V Test reports shall include information about remaining risks.

II, III, V

I, II, IV

I, III, v

II, III, IV

Statements II, III and V are true about test reports. Test reports are documents that provide information on the results and status of testing activities for a given period or phase. Test reports should give stakeholders information as basis for decisions, such as whether to release the software product, whether to continue testing, whether to change the scope or priorities of testing, etc. Test reports should summarize what happened through a period of testing, such as what test cases were executed, what defects were found, what risks were identified, what issues were encountered, what achievements were made, etc. Test reports should include information about remaining risks, such as what defects are still open, what test cases are still pending, what functionalities are still untested, what uncertainties are still unresolved, etc. Statements I and IV are not true about test reports. Test reports do not need to be approved by the test team, the development team, or the customer, unless it is specified by the test policy or the test plan. Test reports only need to be reviewed and verified by the test leader or the test manager before being distributed to the intended recipients.

NEW QUESTION 47
In which of the following cases you would NOT execute maintenance testing?

Retirement of the software or system

Modifications to a released software or system

Migration of the system data to a replacement system

Update to the Maintainability requirements during the development phase

Maintenance testing is testing performed on a software product after delivery to correct defects or improve performance or other attributes. Maintenance testing can be triggered by various situations, such as modifications to a released software or system, migration of the system data to a replacement system, or retirement of the software or system. Maintenance testing is not executed when there is an update to the maintainability requirements during the development phase, as this is not a maintenance situation but rather a change request that should be handled by the development process. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer], Chapter 2, page 18-19.

NEW QUESTION 48
Which type of software development product can undergo static testing?

Any software development product can undergo static testing, including requirements specifications, design specifications and code.

Static tests should be performed on the installation and user guide documents as these documents are used by the end user.

Static testing is done only on the code as part of the “code review” sessions Other documents are reviewed, but not by static testing.

Static testing is done only on the requirements You need to execute the software in order to find defects in the code.

Static testing is a form of testing that does not involve executing the software, but rather analyzing it for defects, errors, or violations of standards. Static testing can be applied to any software development product, including requirements specifications, design specifications, code, test cases, test plans, user manuals, etc. Static testing can be done by using various techniques such as reviews, inspections, walkthroughs, checklists, static analysis tools, etc. Verified Reference: A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer, page 7.

NEW QUESTION 49
For a mandatory input field “ZIP code” the following rules are given:
1 – The valid ZIP code format is 5 numeric digits.
2 – The code has to exist in the post office’s official ZIP code list
Using equivalence classes partitioning, how many test cases are required to test this field?

Equivalence classes partitioning is a technique that divides the input data and output results of a software component into partitions of equivalent data. Each partition should contain data that is treated in the same way by the component. Equivalence classes partitioning can be used to reduce the number of test cases by selecting one representative value from each partition. For the ZIP code field, there are four equivalence classes based on the given rules:
Valid ZIP code format and valid ZIP code value (e.g., 12345)
Valid ZIP code format and invalid ZIP code value (e.g., 99999)
Invalid ZIP code format and valid ZIP code value (e.g., 1234)
Invalid ZIP code format and invalid ZIP code value (e.g., ABCDE) Therefore, four test cases are required to test this field, one for each equivalence class. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer], Chapter 4, page 37-38.

NEW QUESTION 50
Which of the following is a function of a dynamic analysis tool?

Provide support for traceability of tests, test results and incidents to source documents

Monitor the allocation, use and de-allocation of memory during run-time of a program

Execute programs step-by-step in order to reproduce failures and find corresponding defects

Provide support for release of baselines consisting of configuration items

A dynamic analysis tool is a tool that performs analysis of a software product based on its behavior during execution. A dynamic analysis tool can monitor various aspects of a program’s run-time performance, such as memory usage, CPU load, response time, or resource leaks. A dynamic analysis tool can monitor the allocation, use and de-allocation of memory during run-time of a program, which can help detect defects such as memory leaks, buffer overflows, or memory corruption. A dynamic analysis tool cannot provide support for traceability of tests, test results and incidents to source documents, as this is a function of a test management tool. A dynamic analysis tool cannot execute programs step-by-step in order to reproduce failures and find corresponding defects, as this is a function of a debugging tool. A dynamic analysis tool cannot provide support for release of baselines consisting of configuration items, as this is a function of a configuration management tool.

NEW QUESTION 51
Which of the following statements about Experience Based Techniques (EBT) is correct?

EBT use tests derived from the test engineers’ previous experience with similar technologies.

EBT is based on the ability of the test engineer to implement various testing techniques.

EBT is done as a second stage of testing, after non-experienced-based testing took place.

EBT require broad and deep knowledge in testing but not necessarily in the application or technological domain.

Experience based techniques (EBT) are techniques that use the knowledge, intuition and skills of the test engineers to design and execute tests. EBT use tests derived from the test engineers’ previous experience with similar technologies, domains, applications or systems. EBT are not based on the ability of the test engineer to implement various testing techniques, but rather on their personal judgment and creativity. EBT are not done as a second stage of testing, after non-experience-based testing took place, but rather as a complementary or alternative approach to other techniques. EBT require broad and deep knowledge in both testing and the application or technological domain, as this can help the test engineer identify potential risks, scenarios or defects.

NEW QUESTION 52
Which of the following statements regarding inspection is NOT true?

An inspection may be led by a trained moderator who shall not be the author.

The main purpose of an inspection is to find solutions to the problems.

An inspection can be performed by peers.

An inspection shall follow a formal process based on rules and checklists with entry and exit criteria

An inspection is a type of review that follows a defined process with formal entry and exit criteria and roles and responsibilities for participants. An inspection can be performed by peers with different roles, such as moderator, author, reviewer and scribe. The following statement about inspection is not true:
B) The main purpose of an inspection is to find solutions to the problems. This statement is not true, as the main purpose of an inspection is to find defects or issues in a work product, not to find solutions to the problems. Finding solutions to the problems is a debugging or problem-solving activity that is usually performed by the author or developer after receiving the inspection report. The following statements about inspection are true:
A) An inspection may be led by a trained moderator who shall not be the author. This statement is true, as an inspection requires a moderator role who leads the inspection process and ensures that it follows the rules and standards. The moderator should be trained in inspection techniques and should not be the author of the work product under inspection, in order to avoid bias or conflict of interest.
C) An inspection can be performed by peers. This statement is true, as an inspection involves peer review, which means that the work product under inspection is evaluated by people who have similar roles or expertise as the author, but who are not directly involved in creating or modifying the work product.
D) An inspection shall follow a formal process based on rules and checklists with entry and exit criteria. This statement is true, as an inspection follows a formal process that consists of six main steps: planning, kick-off meeting, individual preparation, review meeting, rework and follow-up. Each step has defined rules and checklists to guide the participants and ensure consistency and quality. Each step also has entry and exit criteria to ensure that the prerequisites and objectives are met before moving to the next step.

NEW QUESTION 53
Out of the following. what is not needed to specify in defect report?

Test environment details

How to reproduce the defect

How to fix the defect

Seventy and priority

A defect report is a document that records the details of a defect found during testing. A defect report typically contains the following items:
Identifier: A unique identifier for the defect report
Summary: A concise summary of the defect
Description: A detailed description of the defect, including the steps to reproduce it, the expected and actual results, and any relevant screenshots or logs Severity: The degree of impact that the defect has on the system Priority: The level of urgency for resolving the defect Status: The current state of the defect, such as new, open, resolved, closed, etc.
Resolution: The action taken to resolve the defect, such as fix, workaround, reject, etc. Out of these items, the one that is not needed to specify in a defect report is how to fix the defect. How to fix the defect is a technical solution that is usually determined by the developer who is assigned to resolve the defect. How to fix the defect is not part of the defect report, but rather part of the code change or patch that is delivered to fix the defect. The other items are needed to specify in a defect report, as they provide essential information for identifying, tracking and resolving defects.

NEW QUESTION 54
Which test approach will best fit a new project, with little documentation and high probability for bugs?

Exploratory testing

Requirements based testing

Metric based approach

Regression testing

Exploratory testing is an approach to testing that emphasizes learning, test design and test execution at the same time. Exploratory testing relies on the tester’s skills, creativity and intuition to explore the software under test and discover defects. Exploratory testing is suitable for a new project with little documentation and high probability for bugs, as it can help uncover unknown requirements, assumptions and risks. Exploratory testing is not requirements based testing, which is an approach to testing that derives test cases from documented requirements or specifications. Requirements based testing is not feasible for a new project with little documentation, as it requires clear and complete requirements to be available. Exploratory testing is not metric based approach, which is an approach to testing that uses quantitative measures to monitor and control the testing process and evaluate the quality of the software product. Metric based approach is not effective for a new project with high probability for bugs, as it may not capture all aspects of quality and may lead to false confidence or unrealistic expectations. Exploratory testing is not regression testing, which is an approach to testing that verifies that previously tested software still performs correctly after changes. Regression testing is not relevant for a new project with no previous versions or baselines. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus – Springer], Chapter 5, page 47-48.

NEW QUESTION 55
Which of the following should be included in a test status report?
I Estimation details
II Total number of open and closed defects
III Actual effort spent
IV Defect reports
V Number of executed, failed, blocked tests

III.V

II, III

I. II. IV

II, III.V

The following should be included in a test status report: total number of open and closed defects, actual effort spent, and number of executed, failed, and blocked tests. A test status report is a document that provides information on the results and status of testing activities for a given period or phase. A test status report should include information that is relevant, accurate, and timely for the intended audience and purpose. Some of the information that should be included in a test status report are: total number of open and closed defects, which can indicate the defect trend and defect density of the software product; actual effort spent, which can indicate the productivity and efficiency of the testing process; number of executed, failed, and blocked tests, which can indicate the test progress and test coverage of the software product. The following should not be included in a test status report: estimation details, defect reports, and impact analysis. Estimation details are not part of a test status report, but rather part of a test plan or a test estimation document. Estimation details provide information on the expected time, resources, and costs for testing activities, not on the actual results or status of testing activities. Defect reports are not part of a test status report, but rather separate documents that provide detailed information on individual defects found during testing. Defect reports include information such as defect description, defect severity, defect priority, defect status, defect resolution, etc. Defect reports can be referenced or summarized in a test status report, but not included in full. Impact analysis is not part of a test status report, but rather part of a risk assessment or prioritization process. Impact analysis provides information on the potential effects or consequences of a change or a defect on the software product or project. Impact analysis can be used to evaluate the amount or scope of testing to be performed, but not to report the results or status of testing activities.

NEW QUESTION 56
Which of the following is the most important task of a typical test leader?

To automate tests.

To prepare and acquire test data.

To set up the test environment.

To coordinate the test strategy with project managers.

The most important task of a typical test leader is to coordinate the test strategy with project managers. The test strategy is a high-level document that defines the general approach and objectives of testing for a project or an organization. The test leader is responsible for defining, documenting, communicating, and implementing the test strategy in alignment with the project goals and constraints. The test leader also needs to coordinate with project managers and other stakeholders to ensure that the test strategy is feasible, effective, and efficient. The other options are not the most important tasks of a typical test leader. To automate tests is a task of a test automation engineer or a test automation specialist. To prepare and acquire test data is a task of a test analyst or a test engineer. To set up the test environment is a task of a test environment manager or a test environment specialist.
