Software Testing and Quality Control Questions
-
Penetration testing
-
Service acceptance testing
-
Control testing
B
Correct answer
Explanation
Service acceptance testing is the formal process used to verify that a service meets its defined availability, performance, and functional requirements before it is released into a live environment.
-
a plan of action to resolve the problem and identify effects
-
Implement the solution.
-
Establish a theory of probable cause.
-
Document findings, actions, and outcomes.
D
Correct answer
Explanation
In the standard troubleshooting process, documenting findings, actions, and outcomes is the final step performed after verifying full functionality.
-
It is an open source framework.
-
All of the above.
-
It provides Annotation to identify the test methods.
-
It provides Assertions for testing expected results.
B
Correct answer
Explanation
JUnit is an open-source unit testing framework for Java. It uses annotations to identify test methods and lifecycle phases, and assertions to verify expected outcomes, making all the listed statements correct.
-
Process of writing tests first, then ensuring the tests pass
-
The process of writing tests at the end of development
-
The process of having end users test out the application and report bugs
-
The process of automating deployment of the application and then testing
A
Correct answer
Explanation
Test-Driven Development (TDD) is a development methodology where developers write automated test cases before writing the actual production code. The cycle involves writing a failing test, writing the minimum code to make it pass, and then refactoring the code.
-
Manually testing your application through the GUI or the command line
-
Testing the smallest components of the application in isolation.
-
A way of testing the integration of many different components
-
Having the end users of the application try it out and report bugs
B
Correct answer
Explanation
Unit testing involves testing the smallest testable parts of an application, such as individual methods or classes, in complete isolation from other parts of the system. This ensures that each individual component functions correctly on its own.
-
An integration testing framework for Java
-
A unit test framework for any programming language
-
A unit testing framework for Java
-
A testing library which provides a few helper methods
C
Correct answer
Explanation
JUnit is a widely-used, open-source unit testing framework specifically designed for the Java programming language. It is not intended for any programming language and is primarily for unit testing rather than integration testing.
-
Provide stand-in objects for dependencies to isolate tested code.
-
Modify the tested class state at runtime.
-
Assert values to ensure they meet expectations.
-
Fake unit tests so that they pass regardless of code stability.
A
Correct answer
Explanation
In unit testing, mock objects simulate the behavior of complex, real dependencies (such as databases or external APIs). This allows developers to isolate the code being tested and verify its behavior independently of external factors.
-
Experiment
-
Hypothesis
-
Problem
-
Data/Results
C
Correct answer
Explanation
In the scientific method, the initial question or question being investigated is often referred to as the 'problem.' This defines the purpose of the experiment before a hypothesis is formulated.
-
Thorough Testing
-
Common Standards
-
Careful Design
-
Bigger Teams
D
Correct answer
Explanation
Testing, design, and standards all contribute to reliability. Simply increasing the size of a team does not inherently improve reliability and can sometimes lead to communication overheads.
-
Vulnerability
-
Availability
-
Security Triad
-
Vulnerability Scan
D
Correct answer
Explanation
A vulnerability scan is an automated process that identifies, quantifies, and prioritizes vulnerabilities in a system, network, or application.
-
Automated
-
Manual
-
Complex
-
Dual
B
Correct answer
Explanation
Manual testing relies on human intervention, which can lead to variations in results due to differences in how testers perform the steps or interpret the findings.
-
Manual
-
Complex
-
Automated
-
Dual
C
Correct answer
Explanation
Automated testing uses scripts and tools to execute tests, making it significantly faster and more efficient for repetitive tasks compared to manual testing.
-
Manual
-
Complex
-
Dual
-
Automated
A
Correct answer
Explanation
Manual testing requires a human to step through every part of the application, which is exhaustive and time-consuming compared to automated scripts.
-
Automated
-
Manual
-
Complex
-
Dual
B
Correct answer
Explanation
Manual penetration testing requires deep expertise to understand complex systems, identify subtle vulnerabilities, and think creatively, which automated tools might miss.
-

-
Complex
-
Dual
A
Correct answer
Explanation
Automated penetration testing tools are designed to be user-friendly and provide standardized reports, allowing even beginners to run scans and identify common vulnerabilities.
