Software Testing and Quality Control Questions

Multiple choice

Which of the following is a form of software peer review?

  1. Debugging

  2. Verification

  3. Task analysis

  4. Walk-through

  5. Static program analysis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Walk-through is a form of software peer review in which a designer or programmer leads members of the development team and other interested parties through a software product, and the participants ask questions and make comments about possible errors, violation of development standards, and other problems.

Multiple choice

Which of the following testing types is also known as “field testing”?

  1. Alpha testing

  2. Operational acceptance testing (OAT)

  3. User acceptance testing

  4. Beta testing

  5. Contract and regulation acceptance testing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Beta testing takes place at customers' sites, and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to other customers. It is often called “field testing”.

Multiple choice

Which of the following types of testing is generally not considered during system testing?

  1. Compatibility testing

  2. Graphical user interface testing

  3. White-box testing

  4. Usability testing

  5. Performance testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality.

Multiple choice

Which of the following tests in system analysis is the one in which the programmer simulates each program conclusion or result and exhibits a message to specify whether the program is executed in a successful manner or not?

  1. Unit testing

  2. Stub testing

  3. Integration testing

  4. System testing

  5. Acceptance testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This test in system analysis is the one in which the programmer simulates each program conclusion or result and exhibits a message to specify whether or not the program is executed in a successful manner.

Multiple choice

Which of the following does not occur during the power-on self-test (POST)?

  1. The ScanDisk utility begins to run.

  2. The video card and video memory are tested.

  3. The BIOS identification process occurs.

  4. Memory chips are checked to ensure they are working properly.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

POST (Power-On Self-Test) is a firmware routine that tests essential hardware components like video cards, memory chips, and performs BIOS identification. ScanDisk is a Windows disk-checking utility that runs after the OS boots if needed, not during POST.

Multiple choice

_________ is the process of finding errors in software code.

  1. Debugging

  2. Compiling

  3. Testing

  4. Running

  5. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Testing is the systematic process of finding errors or defects in software code. It involves executing the program with test cases to verify that it behaves correctly and meets requirements, helping identify bugs before the software is released.

Multiple choice

Which of the following is used to ensure that a software is well suited with various hardware platforms, operating systems, other software packages and even previous releases of the same software?

  1. Compatibility testing

  2. Stress testing

  3. Scalability testing

  4. Cyclomatic complexity

  5. Accomplishment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This testing is to ensure that software is well suited with various hardware platforms, operating systems, other software packages and even previous releases of the same software.

Multiple choice

Which testing technique is used to test the internal structures or workings of a program?

  1. Fuzz testing

  2. Grey box testing

  3. White box testing

  4. Visual testing

  5. Black box testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

White box testing tests internal structures or workings of a program. In white box testing, an internal perspective of the system as well as programming skills are used to design test cases. The tester chooses inputs to exercise paths through the code and determine the appropriate outputs.

Multiple choice

For what purpose are assertions used?

  1. Requirement analysis

  2. Feasibility study

  3. Debugging

  4. Beta testing

  5. Designing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A debugger or debugging tool is a computer program that is used to test and debug other programs. Assertions provide a very powerful tool in debugging.
