Software Testing and Quality Control Questions

Multiple choice technology testing
  1. Which of the following is a potential risk in using test support tools?

  1. Underestimating the effort needed to maintain the test assets

  2. Losing access to important testing information when needed

  3. Relying too much on qualitative and quantitative assessments

  4. Lowering the morale of the test team because of repetition
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Test support tools require ongoing maintenance to remain effective. Organizations often underestimate the effort needed to update test scripts, maintain tool configurations, and manage test assets as the system under test evolves. This is a recognized risk in test automation.

Multiple choice technology testing
  1. Which acceptance test is usually performed by system administrators?

  1. Operational

  2. Customer

  3. Contractual

  4. Regulatory
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Operational acceptance testing is typically performed by system administrators to verify that the system meets operational requirements such as backup/recovery procedures, performance under load, and manageability. Customer acceptance is done by users, contractual by legal/business stakeholders, and regulatory by compliance auditors.

Multiple choice technology testing
  1. Which test can be performed at all test levels?

  1. System testing

  2. Operational testing

  3. Structural testing

  4. Integration testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Structural testing (also known as white-box testing) can be performed at all test levels - unit, integration, system, and acceptance. It examines the internal structure and implementation of the software. System and Operational testing are primarily at the system level, while Integration testing focuses on interfaces between components.

Multiple choice technology testing

Operational acceptance testing is done by

  1. Project Managers

  2. Operators of the product

  3. Developers

  4. Technical Experts
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Operational acceptance testing is performed by the end users or operators who will actually use the system in production. This is different from user acceptance testing (which may include business users) - operational testing focuses on operational readiness, maintainability, and recoverability from the operator's perspective.

Multiple choice technology testing

A Test Plan Outline contains which of the following:- i. Test Items ii. Test Scripts iii. Test Deliverables IV. Responsibilities

  1. I, ii, iii are true and iv is false

  2. I , iii, iv are true and ii is false

  3. ii, iii are true and i and iv are false

  4. I , ii are false and iii, iv are true
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A Test Plan document includes test items (features to test), test deliverables (reports, logs, etc.), and responsibilities (roles and tasks). Test Scripts are not part of the Test Plan outline - they are created during test design/specification, which comes later.

Multiple choice technology testing

Which of the following statements regarding static testing is false?

  1. static testing includes desk checking

  2. Static testing requires the running of tests through the code

  3. static testing includes techniques such as reviews and inspections

  4. static testing can give measurements such as cyclomatic complexity
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Static testing involves testing without executing the code - it includes reviews, inspections, walkthroughs, and static analysis tools that examine code structure. Statement B is false because static testing by definition does NOT require running code through execution - that's dynamic testing. Statements A, C, and D correctly describe aspects of static testing.

Multiple choice technology testing

Link Testing is also called as

  1. Component Integration Testing

  2. Component System Testing

  3. Component Sub System Testing

  4. Maintenance Testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Link Testing, which tests the interactions between integrated components, is also known as Component Integration Testing. It focuses on verifying that components can correctly communicate and exchange data. System testing and subsystem testing are broader scopes, and maintenance testing occurs after deployment.

Multiple choice technology testing

Coverage measurement tools are used by

  1. Development team

  2. Testing team

  3. Both

  4. None of the Above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coverage measurement tools are primarily used by the development team during unit and integration testing to measure how much of the code is being exercised by tests. The testing team typically focuses on test design and execution rather than coverage measurement itself.

The ___________ technique can be used to achieve input and output coverage

  1. Boundary value analysis

  2. Equivalence partitioning

  3. Decision table testing

  4. State transition testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Equivalence partitioning is a testing technique that divides input data into groups (equivalence classes) that are expected to be processed similarly. By testing one representative from each equivalence class, you achieve input coverage. For output coverage, you analyze how different input classes map to different output classes. This technique efficiently covers both input and output domains without testing every possible value.

Multiple choice technology testing

Which of the following is the best source of Expected Outcomes for User Acceptance Test scripts?

  1. Actual results

  2. Program specification

  3. User requirements

  4. System specification
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

User Acceptance Testing (UAT) validates that the system meets user requirements and is ready for production. The best source for Expected Outcomes in UAT scripts is the User Requirements, as these define what users actually need the system to do. Program specifications and System specifications are more technical and implementation-focused. Actual results are what you observe during testing, not what you expect.

Multiple choice technology testing

A failure is:

  1. Found in the software; the result of an error.

  2. Departure from specified behaviour.

  3. An incorrect step, process or data definition in a computer program.

  4. A human action that produces an incorrect result.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A failure is a departure from specified behavior - the system doesn't do what it's supposed to do. An error is a human mistake that introduces a defect. A defect/bug is the incorrect code or data definition resulting from an error. When that defect executes, it may cause a failure (observable incorrect behavior). Option B precisely captures this definition of failure as behavioral deviation from specifications.

Multiple choice technology testing

Which of the following is likely to benefit most from the use of test tools providing test capture and replay facilities?

  1. Regression testing

  2. Integration testing

  3. System testing

  4. User acceptance testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Test capture and replay facilities are most valuable for regression testing because they allow you to record test execution once and replay it automatically after code changes. This saves significant time when re-running existing tests to verify that recent modifications haven't broken existing functionality. Integration, system, and user acceptance testing typically require more manual intervention or unique test scenarios each time.

Multiple choice technology testing

Alpha testing is:

  1. Post-release testing by end user representatives at the developer’s site.

  2. The first testing that is performed.

  3. Pre-release testing by end user representatives at the developer’s site.

  4. Pre-release testing by end user representatives at their sites.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Alpha testing is an internal testing phase conducted by end-user representatives or testers at the developer's site prior to release, whereas beta testing is done at the users' own locations.
