Question 1

Which of the following would be a good test technique to use when under severe time pressure?

AExploratory testing

BStructure based testing

CSpecification based testing

DUse Case testing

Answer : A

Exploratory testing would be a good test technique to use when under severe time pressure, because it is a type of experience-based technique that allows testers to design and execute tests based on their intuition, knowledge, and skills, without following a predefined test plan or test cases . Exploratory testing can be useful when testing time is very limited, as it can help to find important defects quickly and adapt to changing requirements or situations . The other options are not good test techniques to use when under severe time pressure. Option B is not a good option, because structure-based testing is a type of technique that requires analysing the code or design of the software under test to measure aspects such as code coverage, complexity, or coupling . Structure-based testing can be time-consuming and may not be feasible or effective when testing time is very limited . Option C is not a good option, because specification-based testing is a type of technique that requires analysing the requirements or specifications of the software under test to design test cases that verify the expected functionality or behaviour . Specification-based testing can also be time-consuming and may not be suitable or efficient when testing time is very limited . Option D is not a good option, because use case testing is a type of technique that requires analysing the use cases or scenarios of the software under test to design test cases that verify the end-to-end user interactions and outcomes . Use case testing can also be time-consuming and may not be relevant or effective when testing time is very limited .

Question 2

Your company is developing a system with complex business rules and many branches in the structure of its code components. You need to choose one black box technique and one white box technique for test case design.

Which one of the following offers the BEST choice?

AStatement testing and exploratory testing

BDecision testing and equivalence partitioning

CDecision testing and decision table testing

DBoundary value analysis and decision table testing

Answer : D

Boundary value analysis and decision table testing are the best choice of one black box technique and one white box technique for test case design2.A black box technique is a technique that uses the external behaviour or specification of a system as a test basis to derive test cases without referring to its internal structure or logic2.A white box technique is a technique that uses the internal structure or logic of a system as a test basis to derive test cases and measure test coverage2. In this question, the system has complex business rules and many branches in the structure of its code components. Therefore, we need to choose a black box technique that can handle complex business rules and a white box technique that can cover many branches.

Boundary value analysis is a black box technique that tests the values at or near the boundaries of an equivalence partition2.Boundary value analysis can handle complex business rules by identifying the boundary conditions that may cause errors or exceptions in the system's behaviour2.

Decision table testing is a white box technique that tests all possible combinations of conditions and actions in a decision logic2.Decision table testing can cover many branches by creating a table that shows how each condition affects each action and then deriving test cases from each row of the table2.

Therefore, boundary value analysis and decision table testing are the best choice of one black box technique and one white box technique for test case design.

Question 3

Which activity in the fundamental test process includes test script generation?

ATest closure activities

BTest analysis and design

CTest planning and control

DTest implementation and execution

Answer : D

Test implementation and execution is the activity in the fundamental test process that includes test script generation.Test script generation is the process of creating executable test cases from test conditions and test data2defines this activity as follows:

Test implementation and execution has the following major tasks:

Develop and prioritize test cases, creating test data and writing test procedures.

Check test environment has been set up correctly.

Execute test cases, evaluate results and document deviations from expected results.

Use exit criteria to report on suitability of system under test.

Test closure activities (A) include finalizing and archiving test results, evaluating the test process, identifying areas for improvement, and celebrating achievements. Test analysis and design (B) include reviewing test basis, identifying test conditions, designing high-level test cases, and defining exit criteria. Test planning and control include defining test objectives, scope, strategy, resources, schedule, risks, and metrics.

Question 4

Which one of the following statements about techniques for estimating test effort is correct?

AThe metrics-based technique finds the most similar former project and uses its original estimate for the current project.

BThe expert-based approach is based on the experience of the owners of the testing tasks or by subject matter experts.

CThe metrics-based technique uses metrics supplied by the current test team based on their subjective feel for effort required.

DIn an expert-based approach, the test lead with the most years in the role is chosen to produce the estimate.

Answer : B

According to the syllabus, there are two main approaches for estimating test effort: metrics-based and expert-based. The metrics-based approach uses metrics from previous similar projects or industry data to calculate the test effort based on the size and complexity of the software under test. The expert-based approach relies on the experience and judgment of the owners of the testing tasks or subject matter experts who provide their estimates based on their knowledge of the software under test. The answer B is correct because it accurately describes the expert-based approach. The other answers are incorrect because they either confuse the metrics-based and expert-based approaches or describe them incorrectly.

Question 5

Which ONE of the following statements does NOT describe how testing contributes to higher quality?

APerforming a review of the requirement specifications before implementing the system can enhance quality

BThe testing of software demonstrates the absence of defects

CProperly designed tests that pass reduce the level of risk in a system

DSoftware testing identifies defects, which can be used to improve development activities.

Answer : B

The statement that does not describe how testing contributes to higher quality is ''The testing of software demonstrates the absence of defects''. This statement is false because testing cannot prove that a software system is defect-free or has a certain level of quality because there might be some untested inputs or outputs that could reveal defects or failures. Testing can only provide information about the quality and risk level of a software system based on the observed behavior and results under certain conditions and assumptions. The other statements describe how testing contributes to higher quality by:

Performing a review of the requirement specifications before implementing the system can enhance quality: This statement is true because reviewing the requirement specifications can help identify and prevent defects, ambiguities, inconsistencies, or incompleteness in the requirements before they are implemented in the system, which can save time and effort and improve customer satisfaction.

Properly designed tests that pass reduce the level of risk in a system: This statement is true because passing tests can increase confidence that the system meets its requirements and expectations and provides value to the users and customers. Passing tests can also reduce the probability or impact of failures or defects in the system that could cause harm or loss.

Software testing identifies defects, which can be used to improve development activities: This statement is true because identifying defects can help analyze and remove their causes and prevent them from recurring in future development activities. Identifying defects can also help improve development processes, methods, standards, tools, techniques, etc., by providing feedback and lessons learned.

You can find more information about how testing contributes to higher quality in [A Study Guide to the ISTQB Foundation Level 2018 Syllabus], Chapter 1.

Question 6

Which of the following BEST matches the attributes with a level of testing?

I, Stubs and drivers are often used

II, The test environment should correspond to the production environment

II,I, Finding defects is not the main focus

IV Testing can be based on use cases

V, Testing is normally performed by testers

VI, Testing for functional and non-functional characteristics

AComponent-V Integration - II, System - IV Acceptance-VI

BComponent -1 Integration - V System - II, Acceptance - IV

CComponent - IV Integration -1 System-VI Acceptance-V

DComponent-VI Integration - IV System -1 Acceptance-II,I
Explanation:

The attributes that best match each level of testing are as follows14:
Component testing: Stubs and drivers are often used (I), as they simulate the behavior of missing or incomplete components.
Integration testing: Testing for functional and non-functional characteristics (VI), as integration testing verifies that components interact correctly and meet their specified requirements.
System testing: The test environment should correspond to the production environment (II,), as system testing evaluates the system's compliance with its specified requirements under realistic conditions.
Acceptance testing: Testing can be based on use cases (IV), as acceptance testing validates that the system meets the user's needs and expectations

Answer : B

Question 7

You have been asked to improve the way test automation tools are being used in your company.

Which one of the following is the BEST approach?

ASelecting and automating scripts that test new functionality to find the most defects

BUsing a keyword-driven testing approach to separate the actions and data from the tool's script

CEnsuring that all data, inputs and actions are stored in the tool's script for ease of maintenance

DKeeping expected results separate from the automation tool to allow the testers to check the results

Answer : B

Using a keyword-driven testing approach to separate the actions and data from the tool's script is the best approach to improve the way test automation tools are being used in your company, because it allows for more flexibility, maintainability, and reusability of automated test scripts1.A keyword-driven testing approach uses keywords or commands to represent actions or data in the test scripts, which can be stored in external files or tables and accessed by the tool1. The other options are not good approaches to improve the way test automation tools are being used in your company.Option A is not a good approach, because selecting and automating scripts that test new functionality to find the most defects does not consider the suitability, feasibility, and cost-effectiveness of automation1.Option C is not a good approach, because ensuring that all data, inputs and actions are stored in the tool's script for ease of maintenance makes the test scripts more rigid, complex, and difficult to modify1.Option D is not a good approach, because keeping expected results separate from the automation tool to allow the testers to check the results reduces the efficiency and reliability of automation and increases the manual effort
