Below are several 2-mark questions along with concise answers covering Unit IV topics:
CODING AND TESTING
-
What is coding in software engineering?
- Coding is the process of writing instructions in a programming language to implement the functionality of a software system.
-
What is code review?
- Code review is a systematic examination of source code to identify bugs, improve quality, and ensure adherence to coding standards.
-
What is software documentation?
- Software documentation refers to written details about a system’s design, functionality, and usage, including user manuals and developer guides.
-
What is black-box testing?
- Black-box testing is a testing technique where the tester examines the system's functionality without knowing the internal code structure.
-
What is white-box testing?
- White-box testing is a testing method where the tester has knowledge of the internal code and tests the software’s logic and structure.
-
What is debugging?
- Debugging is the process of identifying, analyzing, and fixing errors or bugs in a software program.
-
What are program analysis tools?
- Program analysis tools help developers analyze and detect errors in software code, such as static analyzers and dynamic analyzers.
-
What is integration testing?
- Integration testing is the process of testing combined software modules to ensure they work together correctly.
-
What is object-oriented testing?
- Object-oriented testing focuses on testing object-oriented software components like classes, objects, and methods.
-
What is smoke testing?
- Smoke testing is a preliminary test to check whether the critical functionalities of a software build work before further testing.
-
What is regression testing?
- Regression testing is done to check if recent code changes have not adversely affected existing functionalities.
-
What is the purpose of software testing?
- The purpose of software testing is to identify defects, ensure quality, and validate that software meets the specified requirements.
SOFTWARE RELIABILITY AND QUALITY MANAGEMENT
-
What is software reliability?
- Software reliability is the probability that a software system will function without failure under specified conditions for a given time.
-
What is statistical testing?
- Statistical testing involves using probabilistic methods to estimate software reliability and performance.
-
What is software quality?
- Software quality refers to how well software meets functional and non-functional requirements, ensuring reliability, efficiency, and maintainability.
-
What is a Software Quality Management System (SQMS)?
- SQMS is a framework that ensures software quality through planned processes, standards, and quality control measures.
-
What is ISO 9000 in software engineering?
- ISO 9000 is a set of international standards for quality management and assurance in software development.
-
What is the SEI Capability Maturity Model (CMM)?
- SEI CMM is a framework that assesses and improves software development processes based on maturity levels.
-
What are the five maturity levels of CMM?
- The five levels of CMM are: Initial, Repeatable, Defined, Managed, and Optimizing.
-
What is Six Sigma in software quality management?
- Six Sigma is a data-driven approach to process improvement that aims to reduce defects and improve quality.
-
What is defect density?
- Defect density is the number of defects per unit size of code, typically measured in defects per KLOC (thousand lines of code).
-
What are some important software quality standards?
- Important quality standards include ISO 9001, ISO 27001, CMMI, and Six Sigma.
-
What is software verification?
- Software verification checks if the software meets design specifications and standards.
-
What is software validation?
- Software validation ensures that the final product meets user requirements and functions correctly.
-
What is reliability testing?
- Reliability testing assesses whether a software system performs consistently under specific conditions over time.
