Software Testing and Quality Control Questions

Multiple choice

Equivalence partitioning is related to what type of software testing?

  1. Black box testing

  2. White box testing

  3. Usability testing

  4. Stress testing

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

Equivalence partitioning is generally related to black box testing, which is strictly checking a software component at its interface, without consideration of internal structures of the software.

Multiple choice

An installed fiber run can be checked for faults, integrity, and the performance of the media by using what device?

  1. light injector

  2. OTDR

  3. TDR

  4. multimeter
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An Optical Time Domain Reflectometer (OTDR) is the specialized device used to test fiber optic installations. It sends light pulses into the fiber and analyzes the backscattered light to detect faults, measure fiber length, identify bends or breaks, and assess overall signal integrity and performance characteristics. TDR is for copper cables, multimeters measure electrical signals, and light injector is not a standard testing tool.

Multiple choice

The artifact that contains procedure, or programing code that replicates user actions is called

Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. The software testing process can produce several artifacts.

  1. test plan

  2. traceability matrix

  3. test case

  4. test script

  5. test suite
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A test script is a procedure, or programing code that replicates user actions. Initially the term was derived from the product of work created by automated regression test tools. Test Case will be a baseline to create test scripts using a tool or a program.

Multiple choice

Which of the following is a type of functional testing? Functional testing is a quality assurance process and a type of black box testing that bases its test cases on the specifications of the software component under test.

  1. System testing

  2. Compatibility testing

  3. Regression testing

  4. Load testing

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

Regression tests can be broadly categorized as functional tests or unit tests. Functional tests exercise the complete program with various inputs. Unit tests exercise individual functions, subroutines, or object methods. Both functional testing tools and unit testing tools tend to be third-party products that are not part of the compiler suite, and both tend to be automated.

Multiple choice

Which of the following test and evaluation activities is typically conducted on large, complex systems such as aircraft and military acquirer activity systems?

  1. Developmental testing and evaluation

  2. Operational test and evaluation

  3. Decision support systems

  4. None of these
