Which of the problems below BEST characterize a result of software failure Damaged
reputation
What is the primary purpose of software testing?
To identify defects and ensure the software meets quality standards.
Define the principle of "exhaustive testing" in software testing.
Exhaustive testing means testing all possible input combinations, which is often impractical
in real-world scenarios due to time and cost constraints.
Why is early testing important in the software development lifecycle?
Early testing helps detect defects sooner, reducing the cost and effort required to fix them
later in development.
Explain the role of static testing in the software testing process.
Static testing involves reviewing and analyzing code or documents without executing them,
helping to find defects early.
What is a review in the context of static testing?
1
, A review is a static technique used to examine software products to identify issues and
improve quality without executing the code.
What are some common deliverables in the test planning phase?
Test plans, test cases, test scripts, and test data are common deliverables in the test planning
phase.
In static analysis, what is the purpose of a code walkthrough?
A code walkthrough allows team members to review the code for potential issues, errors, and
improvements by going through it line-by-line.
Describe the principle of defect clustering in software testing.
Defect clustering states that a small number of modules or components typically contain the
majority of defects.
What is meant by "the pesticide paradox" in testing?
The pesticide paradox suggests that running the same set of tests repeatedly may not reveal
new defects; tests need to be regularly reviewed and updated.
Define the objective of static analysis tools.
Static analysis tools analyze code for potential defects, coding standards violations, and
security vulnerabilities without executing the code.
2
, What is meant by test coverage in software testing?
Test coverage is a measure of how much of the application’s code or features are tested,
helping to identify untested areas.
Why is it essential to use different levels of testing?
Different levels of testing, such as unit, integration, and system testing, help identify defects
in various aspects of the application.
What is a primary benefit of static techniques in the software development process?
Static techniques can identify defects early, reducing rework and saving time and costs in the
development lifecycle.
Explain the term "false positive" in static analysis.
A false positive occurs when a static analysis tool flags an issue that is not actually a defect,
potentially leading to unnecessary investigation.
What does a code inspection involve in static testing?
A code inspection involves a formal review process where peers examine the code to find
defects and ensure compliance with standards.
What is meant by "dynamic testing"?
Dynamic testing involves executing the software to identify defects through interaction with
the application.
