Question 1

When testing individual modules,it sometimes happens that some modules are not finished when testing starts,so the programmer usually writes _______ for the unfinished modules to enable the modules around them to be tested.
A)"By-passes"
B)"Temporary Modules"
C)"Placeholder Modules"
D)"Stub Modules"
E)"End Modules"

Accepted Answer

When testing individual modules, if some modules are not finished when testing starts, the programmer usually writes stub modules for the unfinished modules to enable the modules around them to be tested. Stub modules act as a temporary replacement for the unfinished module within the context of the testing environment.

Question 2

System tests are usually conducted by:
A)Programmers (developers)
B)Project managers
C)Users
D)Systems analysts
E)Project sponsors or project champions

Accepted Answer

The answer of System tests are usually conducted by:
A)Programmers (developers)
B)Project...

Question 3

The test objective is taken directly from:
A)The results of the JAD session
B)The program specification
C)The use-cases
D)The project sponsor
E)The questions raised in a focus-group application

Accepted Answer

The test objective should come from the program specification as this outlines the desired behavior of the software and what needs to be tested. The other options may provide useful information, but they may not provide a comprehensive view of the testing objectives.

Question 4

Especially with interactive forms,testing should:
A)Include batch data processing
B)Omit data validation
C)Include certain combinations of commands or menu choices
D)Only be done by real users with real data on the job
E)None of the above

Accepted Answer

Especially with interactive forms, testing should include certain combinations of commands or menu choices. This is important to ensure that the form behaves correctly when the user tries to accomplish a task using different sequences of input. Batch data processing and data validation are important aspects of testing, but they are not specific to interactive forms. Testing by real users with real data can also be helpful, but it may not always be practical or feasible.

Question 5

On test plans:
A)Each individual test has a specific objective and describes a set of very specific test cases to examine
B)Each user must contribute to the specific goals of the test plan
C)Each member of the project team, plus all developers (programmers)must identify one specific application that they will test
D)Only the master project manager tests, and only after all coding has been completed in what is called the "Omega" test
E)The use of multiple choice options has been shown to effectively assess to a 99.9% accuracy rate

Accepted Answer

Test plans should include specific objectives for each test, along with a set of specific test cases to achieve those objectives. This helps ensure comprehensive testing and clear identification of any issues found during testing. The other options are not accurate or helpful for effective test planning.

Question 6

Unit tests focus on:
A)All modules (all units)
B)Users and their acceptance of how a specific unit works
C)A program or a program module
D)Interact screen forms
E)How the overall system functions

Accepted Answer

Unit tests focus on testing individual program or program modules to ensure they are functioning properly.

Question 7

Test plans:
A)Are generally developed by the programmers informally
B)Generally only cover main processing and not the various sub-processes
C)Often have 20 to 30 pages
D)Can be massive with over 200 pages of very explicit plans and directions
E)Can generally be written in three pages or less

Accepted Answer

The answer of Test plans:
A)Are generally developed by the programmers...

Question 8

Integration testing:
A)Is to verify that batch processing and online processing both work together
B)Assesses if a set of modules or programs that are to work together, do so
C)Is a cross between black-box and white-box testing
D)Verifies that client side applications and server side applications do work together
E)Rarely turns up errors or defects

Accepted Answer

Integration testing is focused on verifying that a set of modules or programs that are to work together, do so. It is performed after unit testing and before system testing. Option A is incorrect because it is focused on testing batch processing and online processing separately, while integration testing is focused on testing how they work together. Option C is incorrect because integration testing is not necessarily a cross between black-box and white-box testing - both techniques can be used in integration testing depending on the approach. Option D is also incorrect because it is focused on verifying client-side and server-side applications, which is not the main focus of integration testing. Option E is incorrect because integration testing can actually reveal a significant number of errors or defects - this is why it is an important part of software testing.

Question 9

There are two approaches to unit testing:
A)Alpha and beta
B)Yin and Yang
C)Numerical and alphabetical
D)Valid and invalid
E)Black-box and white-box

Accepted Answer

Black-box and white-box are the two main approaches to unit testing. Black-box testing is when the tester only looks at the inputs and outputs of a function without examining the internal workings. White-box testing is when the tester looks at the internal workings of the function to ensure that it is working correctly. Both approaches are important and should be used together for comprehensive unit testing.

Question 10

A program is not considered finished until:
A)It has been used successfully for six months
B)The cost of developing the program 'breaks-even' with the benefits of the program
C)The ROI is positive
D)It has passed its testing
E)It 'dies' and is replaced by a newer version

Accepted Answer

Passing testing ensures that the program is functioning correctly and meeting the specified requirements. While ongoing usage, cost-benefit analysis, and ROI are important considerations for a program's success, passing testing is a necessary step in ensuring that the program is complete and can be considered finished. Option A and E are not relevant criteria for determining the completion of a program, while option B and C are important but not sufficient on their own.

Question 11

Black-box testing:
A)Is reserved for special circumstances in which the tester wants to review the actual program code
B)Is reserved for NASA space missions
C)Is reserved for very complex systems
D)Is only used by highly skilled testers
E)None of the above

Accepted Answer

Black-box testing is a testing method where the tester is only concerned with the functionality of the system without knowledge of the internal structure or workings of the system. It is not reserved for any specific circumstances, system complexity, or level of tester skill. It is a widely used testing approach in software development.

Question 12

Integration testing focuses on ___________;while system tests focus on _______________.
A)Modules working together; meeting business requirements
B)Black-box tests; white-box tests
C)End-users acceptance; project sponsor acceptance
D)DFDs; ERDs
E)Beta tests; alpha tests

Accepted Answer

Integration testing is focused on testing whether the different modules of a system are working together seamlessly. On the other hand, system testing is focused on testing whether the system meets the business requirements and specifications.

Question 13

Which of the following is NOT a general test stage?
A)Unit tests
B)Module tests
C)Integration tests
D)System tests
E)Acceptance tests

Accepted Answer

Module tests are not a general test stage. Unit tests, integration tests, system tests, and acceptance tests are all generally recognized stages of testing. Module tests are specific to certain development methodologies, such as object-oriented programming where a module is a small, independent portion of code within a larger system.

Question 14

Which of the following is NOT an approach to integration testing?
A)Use-case testing
B)User interface testing
C)Use scenario testing
D)Data flow testing
E)System interface testing

Question 16

The authors suggest that:
A)"All testing must include live production data"
B)"All testing must include both alphabetic and numeric data"
C)"It is impossible to test every possible combination of input and situation"
D)"Testing rarely pays for itself"
E)"Testing should only be used for complex programs and situations"

Accepted Answer

The authors suggest that it is impossible to test every possible combination of input and situation, indicating that exhaustive testing is not feasible. The other options are not mentioned or suggested by the authors.

Question 17

Generally,most errors (defects)are found in which two testing periods?
A)Unit testing and integration testing
B)Integration testing and system testing
C)System testing and acceptance testing
D)Unit testing and acceptance testing
E)Alpha testing and beta testing

Accepted Answer

The answer of Generally,most errors (defects)are found in which two...

Question 18

Which of the following is probably something that system testing WILL NOT verify?
A)Systems documentation
B)Ability to perform under heavy load
C)Conformance to Sarbanes-Oxley requirements
D)How well the system meets business requirements
E)The systems usability

Accepted Answer

System testing typically focuses on verifying the functional and non-functional requirements of the system, such as its ability to perform under heavy load, how well it meets business requirements, and its usability. Sarbanes-Oxley requirements, on the other hand, are related to financial regulation and may fall outside the scope of system testing. Systems documentation, while important, is typically verified through other means such as reviews or inspections.

Question 19

As compared to integration testing,system testing:
A)Is much broader in scope
B)Uses production data (rather than test data)
C)Is done by hand-picked end-users (rather than systems analysts)
D)Involves both black-box and red-box testing
E)Makes more extensive use of stubs

Accepted Answer

System testing covers the entire system and tests the functionality and performance of the system as a whole. It involves conducting tests on the integrated system and verifying if the system is meeting the specified requirements. Integration testing, on the other hand, focuses on testing the interfaces between the modules and ensuring that they work as expected when combined. Therefore, system testing is much broader in scope than integration testing.

Question 20

Acceptance tests are done primarily by:
A)Programmers
B)Users
C)Developers
D)Systems Analysts
E)Project Managers

Accepted Answer

Acceptance tests are done primarily by users who check if the software meets their requirements and if it is ready to be deployed. Programmers, developers, systems analysts, and project managers may be involved in defining the acceptance criteria, but they should not execute the tests themselves.
