Q38. Confirmation testing is performed after:

a defect is fixed and after other tests do not find any side-effect introduced in the software as a result of such fix

a failed test, and aims to run that test again to confirm that the same behavior still occurs and thus appears to be reproducible

the execution of an automated regression test suite to confirm the absence of false positives in the test results

a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed

Q39. In addition to thorough testing of the requirements specification, a development team aims to involve users as early as possible in the development process, using practices such as prototyping, to ensure that the software systems being developed will meet the users’ expectations.

Traceability between test basis items and thetest casesdesigned tocover them,enablesexperience-based test techniques to be applied

Traceability between test basis items and thetest casesdesigned tocover them,enablesidentification of which test cases will be affected by changes to the test basisitems

Traceability can be established and maintained throughall test documentation for a giventest level, such as from test conditions through test cases to test scripts

Q43. Which of the following statements is true?

In Agile software development, work product documentation tends to be lightweight and manual tests tend to be often unscripted as they are often produced using experience-based test techniques

Sequential development models impose the use of systematic test techniques and do not allow the use of experience-based test techniques

In Agile software development, the first iterations are exclusively dedicated to testing activities, as testing will be used to drive development, which will be performed in the subsequent iterations

Both in Agile software development and in sequential development models, such as the V-model, test levels tend to overlap since they do not usually have defined entry and exit criteria

Q44. Which of the following statements is CORRECT?

Testing the software under test (SUT) based on the design is black-box testing whereas testing the input-output behaviour is experience based testing.

Testing the software under test (SUT) is possible only after implementation in white-box testing whereas testing the software even before implementation is possible in exploratory testing.

Testing the software under test (SUT) using knowledge of the tester is experience based testing whereas testing the specification based behaviour without pre-written test cases is using black-box testing techniques.

Testing based on the structure of the software under test (SUT) is white-box testing whereas testing the input-output behaviour without pre-written test cases is experience based testing.

Q45. In a two-hour uninterrupted test session, performed as part of an iteration on an Agile project, a heuristic checklist was used to help the tester focus on some specific usability issues of a web application.
The unscripted tests produced by the tester’s experience during such session belong to which one of the following testing quadrants?

Q1

Q2

Q3

Q4

The unscripted tests produced by the tester’s experience during the two-hour test session belong to the testing quadrant Q3. The testing quadrants are a classification of testing types based on two dimensions: the test objectives (whether the testing is focused on supporting the team or critiquing the product) and the test basis (whether the testing is based on the technology or the business). The testing quadrants are labeled as Q1, Q2, Q3, and Q4, and each quadrant represents a different testing perspective, such as unit testing, acceptance testing, usability testing, or performance testing. The testing quadrant Q3 corresponds to the testing types that have the objective of critiquing the product from the business perspective, such as exploratory testing, usability testing, user acceptance testing, alpha testing, beta testing, etc. The unscripted tests performed by the tester in the given scenario are examples of exploratory testing and usability testing, as they are based on the tester’s experience, intuition, and learning of the web application, and they focus on some specific usability issues, such as the user interface, the user satisfaction, the user feedback, etc. The other options are incorrect, because:
The testing quadrant Q1 corresponds to the testing types that have the objective of supporting the team from the technology perspective, such as unit testing, component testing, integration testing, system testing, etc. These testing types are usually performed by developers or testers who have access to the source code, the design, the architecture, or the configuration of the software system, and they aim to verify the functionality, the quality, and the reliability of the software system at different levels of integration.
The testing quadrant Q2 corresponds to the testing types that have the objective of supporting the team from the business perspective, such as functional testing, acceptance testing, story testing, scenario testing, etc. These testing types are usually performed by testers or customers who have access to the requirements, the specifications, the user stories, or the business processes of the software system, and they aim to validate that the software system meets the expectations and the needs of the users and the stakeholders.
The testing quadrant Q4 corresponds to the testing types that have the objective of critiquing the product from the technology perspective, such as performance testing, security testing, reliability testing, compatibility testing, etc. These testing types are usually performed by testers or specialists who have access to the tools, the metrics, the standards, or the benchmarks of the software system, and they aim to evaluate the non-functional aspects of the software system, such as the efficiency, the security, the reliability, or the compatibility of the software system under different conditions or environments.

Q46. Which ONE of the following options CORRECTLY describes one of the seven principles of the testing process?

The objective of testing is to implement exhaustive testing and execute as many test cases as possible.

Exhaustive testing can only be carried out using behavior-based techniques.

It is impossible to test all possible combinations of inputs and preconditions of a system.

Automated testing enables exhaustive testing.

Q47. Consider the following examples of risks identified in different software development projects:
[I]. The contrast color ratio for both normal text and large text of a website does not comply with the applicable accessibility guidelines, making it difficult for many users to read the content on the pages
[II]. A development vendor fails to deliver their software system on time, causing significant delays to system integration testing activities that have been planned as part of a development project for a system of systems
[III]. People in the test team do not have sufficient skills to automate tests at the test levels required by the test automation strategy which does not allow production of an effective regression test suite
[IV]. In a web application, data from untrusted sources is not subject to proper input validation, making the application vulnerable to several security attacks Which of the following statements is true?

[I] and [III] are product risks; [II] and [IV] are project risks

[I] and [IV] are product risks. [II] and [III] are project risks

[II], [III] and [IV] are product risks; [I] is a project risk

[IV] is a product risk; [I]. [II] and [III] are project risks
