What is the primary goal of software quality assurance (SQA)?
Manage project budgets
Design the software architecture
Maximize code execution speed
Ensure software meets defined requirements and standards
Software quality assurance focuses on verifying that the product meets specified standards and requirements. SQA implements processes and guidelines to prevent defects and ensure consistent quality.
Which document specifies the inputs, execution conditions, and expected results for a software test?
Test strategy
Defect report
Test case
Requirements specification
A test case details specific inputs, preconditions, execution steps, and expected outcomes for a test. It serves as the basic unit of test execution in quality assurance.
Which testing technique involves the examination of software artifacts without executing code?
Static testing
Load testing
Dynamic testing
Unit testing
Static testing refers to activities like reviews and inspections where the code is not executed. It helps identify defects early by analyzing code, design documents, or requirements.
In which testing approach does the tester focus solely on software requirements and functionality without knowing its internal structure?
Grey-box testing
Black-box testing
White-box testing
Unit testing
Black-box testing evaluates software based on requirements and expected behaviors without examining internal code. Testers design tests using input-output specifications only.
What best describes exploratory testing?
Testing based on risk priority alone
Executing only automated test scripts
Simultaneous learning, test design, and execution without predefined test cases
Following a fixed set of scripted tests
Exploratory testing is an unscripted approach where testers design and execute tests on the fly while learning the application. It emphasizes flexibility and real-time defect discovery.
Which software quality model organizes process improvement into maturity levels ranging from Initial to Optimizing?
Capability Maturity Model Integration (CMMI)
ITIL
Six Sigma
ISO 9001
CMMI defines a framework of maturity levels from Initial to Optimizing to guide process improvement. It helps organizations evolve processes from ad hoc to continuous optimization.
How is defect density calculated in software quality metrics?
Average time to resolve defects
Total number of defects divided by number of test cases
Number of defects per thousand lines of code
Ratio of passed tests to failed tests
Defect density measures the number of defects found relative to the size of the codebase (typically per KLOC). It provides a standardized way to compare quality across modules.
Which test design technique divides input data into groups that are expected to behave similarly?
Boundary value analysis
Equivalence partitioning
Decision table testing
State transition testing
Equivalence partitioning groups inputs into classes that are expected to produce similar results. It reduces the total number of test cases while maintaining effective coverage.
What does risk exposure in software projects represent?
Ratio of high-priority to low-priority tests
Probability of a risk event multiplied by its impact
Difference between planned and actual schedule
Total number of identified risks
Risk exposure quantifies the potential impact by combining the likelihood of occurrence with the severity of consequences. It helps prioritize mitigation efforts.
Which key component is typically included in a test plan document?
Software architecture diagrams
Detailed code review checklist
Complete list of software defects
Scope and objectives of testing
A test plan outlines the scope, objectives, resources, schedule, and approach for testing activities. It serves as the blueprint to guide test execution and monitoring.
What is the primary purpose of regression testing?
To verify that recent changes have not adversely affected existing functionality
To test the installation process
To validate user interface design
To find performance bottlenecks
Regression testing re-executes previously run tests after changes to ensure existing functionality still works. It helps maintain stability as software evolves.
What is boundary value analysis primarily used for?
Testing at the edges of input domains
Checking code for security vulnerabilities
Validating user interface compliance
Stress testing under heavy loads
Boundary value analysis focuses on input values at the edge of equivalence partitions to identify defects at limits. These boundary tests often uncover errors not found by typical values.
Which debugging technique involves isolating code segments by systematically enabling or disabling parts of the code?
Delta debugging
Pair programming
Test-driven development
Benchmarking
Delta debugging automates the process of isolating failure-inducing code by iteratively narrowing down changes. It systematically enables or disables segments to find the minimal cause.
Which international standard focuses specifically on quality management systems, including software organizations?
CMMI
IEEE 829
ISO 27001
ISO 9001
ISO 9001 specifies requirements for a quality management system applicable to any organization. It provides a framework for consistent quality processes and continual improvement.
Which test automation framework is most commonly used for unit testing in Java applications?
JUnit
Selenium
Cucumber
TestComplete
JUnit is a widely adopted framework for writing and executing unit tests in Java. It offers annotations, assertions, and integration with build tools for automated testing.
What does Modified Condition/Decision Coverage (MC/DC) measure in software testing?
Percentage of statements executed during testing
Number of test cases covering each branch
Each condition independently influences the decision outcome
Ratio of functions tested to total functions
MC/DC requires that each logical condition within a decision be shown to independently affect the decision's outcome. It is crucial for verifying complex decision logic, especially in safety-critical systems.
In Six Sigma's DMAIC process, what does the "Analyze" phase primarily involve?
Defining project goals and scope
Implementing and validating solutions
Measuring current process performance
Analyzing data to identify root causes of defects
The Analyze phase uses statistical tools and data analysis to uncover the underlying causes of process defects. Identifying root causes is essential before implementing corrective actions.
Which root cause analysis tool uses a cause-and-effect diagram to systematically explore potential factors leading to a defect?
Control chart
Pareto chart
Fishbone diagram
Scatter diagram
A fishbone (Ishikawa) diagram visually categorizes potential causes of a problem into major groups. It helps teams explore all possible factors contributing to a defect systematically.
What is the primary objective of Failure Mode and Effects Analysis (FMEA) in risk management?
Identify coding errors in each module
Automate the execution of test cases
Prioritize potential failure modes by severity and likelihood
Perform load testing under stress conditions
FMEA assesses each potential failure mode by ranking its severity, occurrence likelihood, and detectability. This produces a risk priority number guiding mitigation of the highest risks.
In the CMMI framework, what characterizes organizations at Maturity Level 3 (Defined)?
Processes are continuously improved based on feedback
Processes are standardized, documented, and tailored from organizational standards
Processes are quantitatively managed with metrics
Processes are unpredictable and reactive
At Maturity Level 3, organizations have established standard processes across projects, documented in a process asset library, and tailored as needed. This ensures consistency and repeatability.
