Software Engineering is part of Computer Science and holds 1,969 questions with answers, free to read and with no account needed.
Questions from this area appear in PPSC, FPSC, NTS, KPPSC and SPSC papers. Each guide explains how that paper is built and which subjects carry it.
Attempt each question before revealing the answer, and keep a note of the ones you get wrong — those are the topics worth reading about properly. If an answer looks wrong, there is a link to report it on every question.
Answer: A. Nonexistent loop termination
Test cases should aim to expose common defects such as nonexistent loop termination during software execution. Identifying infinite loops prevents resource exhaustion and application crashes during production usage. Targ...
Answer: A. Error description is unintelligible
Unintelligible error descriptions provide zero diagnostic value and must be excluded from metrics. If an error cannot be understood or located, it cannot contribute to useful handling analysis. Valid error metrics requir...
Answer: B. 4GT
4GT stands for Fourth Generation Technique, which is a software development model. It focuses on generating code from high level specifications rather than iterative agile cycles. Agile methodologies prioritize iterative...
Answer: B. access-controlled library
Shared software code is stored in an access-controlled library to maintain version integrity. Access controls ensure that only authorized developers can modify official project source files. Centralized libraries prevent...
Answer: B. Baseline
A baseline represents formally reviewed configuration items that establish a stable foundation for subsequent work. Approved documentation and code snapshots form baselines that require formal change control procedures....
Answer: B. Internal Failure
Internal failure costs arise when defects are identified during development before product delivery to customers. These costs include the effort required for debugging rework and retesting flawed software components. Min...
Answer: C. Breadth test and depth test
Maintenance testing utilizes breadth and depth tests to ensure that recent modifications do not break functionality. Breadth tests cover a wide range of system features to verify overall stability after a software patch....
Answer: D. all of the mentioned
Comprehensive testing requires executing test cases across diverse data, cases, and variables. Covering all input variations ensures hidden edge cases and logic flaws are exposed. Restricting tests to only one element wo...
Answer: B. Unit testing
Unit testing is performed immediately after writing code by the developer themselves. It verifies the smallest testable parts of an application functioning in isolation. This close temporal relationship makes unit testin...
Answer: A. Bug prevention
While finding bugs is essential, the ultimate objective of software testing is bug prevention. Analyzing testing patterns helps teams eliminate root causes and prevent similar defects in future cycles. Proactive quality...
Answer: D. Configuration Control Board
The Configuration Control Board acts as the formal authority for evaluating proposed system baseline modifications. This specialized group reviews technical and financial impacts before approving any baseline changes. Ch...
Answer: B. Quality of conformance
Quality of conformance measures the extent to which the manufactured product adheres to design specifications. It evaluates whether the resulting software implementation accurately reflects the approved architectural des...
Answer: C. impractical but possible
Exhaustive testing is practically impossible because modern software systems contain an infinite number of input combinations. Testing every single execution path requires more computational resources and time than any p...
Answer: C. Version
A version defines a distinct, specific revision or instance of a software configuration item. Versioning allows development teams to track incremental changes over time accurately. Each released or saved revision receive...
Answer: A. Version Control
Version control systems manage multiple developer contributions to shared source files simultaneously. They merge concurrent edits and track every modification made throughout development. Developers rely on this mechani...
