Question 1

A team's test strategy was to invest equal effort in testing each of a system's modules. After running one test cycle, it turned out that most of the critical bugs were detected in one of the system's modules.

Which testing principal suggests a change to the current test strategy for the next test cycle?

ADefect clustering

BEarly testing

CPesticide Paradox

DAbsence-of-errors fallacy

Answer : A

Defect clustering is the phenomenon that a small number of modules contain most of the defects detected. This principle suggests that testing should focus more on the areas where defects are more likely to occur, rather than spreading the testing effort equally across all modules. Therefore, in the next test cycle, the team should allocate more resources to test the module that had most of the critical bugs.

Question 2

Which of the following sentences about testing and debugging is correct?

ARe-testing checks that debugging has found and analyzed the failure

BDynamic testing finds defects, while debugging removes failures

CDynamic testing reveals failures, while debugging removes defects

DLike most development activities, debugging is usually done before testing starts

Answer : C

Testing and debugging are two different activities that are related to finding and removing defects and failures in software. Testing is the process of evaluating software by applying test cases to find failures and provide information on its quality. Debugging is the process of finding, analyzing, and removing the causes of failures in software. Testing reveals failures, which are deviations of the actual behavior of the software from its expected behavior. Debugging removes defects, which are flaws in the software that cause failures.

Question 3

Which of the following processes ensures that all items of testware are identified, version controlled, tracked for changes, so that traceability can be maintained throughout the test process?

ASoftware traceability process

BIncidence management process

CTesting design process

DConfiguration management process

Answer : D

The process that ensures that all items of testware are identified, version controlled, tracked for changes, so that traceability can be maintained throughout the test process is D. Configuration management process. Configuration management is a process that establishes and maintains the integrity and consistency of all items of testware throughout the test process. Configuration management involves identifying, storing, controlling, tracking, and auditing all items of testware (such as test plans, test cases, test scripts, test data, test results, etc.) and their versions and changes. Configuration management helps to ensure that only authorized and approved items of testware are used for testing and that traceability can be maintained between them. A detailed explanation of configuration management can be found inA Study Guide to the ISTQB Foundation Level 2018 Syllabus, pages 101-1021.

Question 4

You are testing an e-commerce system The system accepts four different types of Credit Cards; each card has its own rules for valid and invalid numbers. The following is a portion of the Decision Table for Order Management.:

The combination of the conditions Valid Card Number (NO) + Purchase Approved (YES) is not feasible.

You wish to perform a test which completely covers all the combinations of equivalence partitioning tor the different types of credit card, according to the rules shown in the above Decision Table

How many test cases do you need?

C16

D12

Answer : C

The combination of the conditions Valid Card Number (NO) + Purchase Approved (YES) is not feasible, as a purchase cannot be approved with an invalid card number. Therefore, this combination can be ignored in the equivalence partitioning for the different types of credit card. Each type of credit card has two valid equivalence partitions: Valid Card Number (YES) + Purchase Approved (YES) and Valid Card Number (YES) + Purchase Approved (NO). Each type of credit card also has one invalid equivalence partition: Valid Card Number (NO) + Purchase Approved (NO). Therefore, to cover all the combinations of equivalence partitions for the four types of credit card, we need 4 x (2 + 1) = 12 test cases.

A, B, and D are incorrect answers. A implies that there are two equivalence partitions for each type of credit card, which is not true as there are three. B implies that there is only one equivalence partition for each type of credit card, which is not true as there are two valid ones and one invalid one. D implies that there are four equivalence partitions for each type of credit card, which is not true as there are only three.

Question 5

Which of the following lists represents the correct sequence of the main activities of the fundamental test process (leaving out the activity of control which should take place in parallel to all the other activities)?

APlanning, analysis and reporting, design and implementation, execution, test closure activities, evaluating exit criteria.

BPlanning, analysis, design and implementation, execution, logging, test closure activities, evaluating exit criteria.

CPlanning, analysis and design, execution, logging and reporting, regression testing

DPlanning, analysis and design, implementation and execution, evaluation exit criteria and reporting, test closure activities

Answer : D

Question 6

Which of the following statements contradicts the general principles of testing?

AIf new defects are to be found, we should run the same test set more often

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

CTesting is better if it starts at the beginning of a project

DMost defects are found in a small subset of a system's modules

Answer : A

The general principles of testing state that testing can show the presence of defects, but not their absence. Running the same test set more often will not increase the likelihood of finding new defects, unless the system or its environment changes. Therefore, statement A contradicts the general principles of testing. Statement B is true, as testing is context-dependent and should be tailored to the specific situation of a project. Statement C is also true, as early testing can help prevent defects and reduce rework. Statement D is true, as it reflects the Pareto principle or the 80/20 rule, which states that most defects are found in a small subset of a system's modules.

Question 7

Dynamic Analysis Tools are used to:

ADetermine differences between files or databases.

BMonitor and report on how a system behaves under a variety of conditions.

CFind defects, such as memory leaks, while software is executing.

DMeasure the percentage of specific types of code structure that have been exercised.

Answer : C

Dynamic analysis tools are used to find defects, such as memory leaks, while software is executing. Dynamic analysis tools monitor the behavior and performance of the software under various conditions and report on any anomalies or errors. Dynamic analysis tools are not used to determine differences between files or databases, which is a function of comparison tools. Dynamic analysis tools are not used to measure the percentage of specific types of code structure that have been exercised, which is a function of code coverage tools.
