Software Testing and Quality Control Questions

Multiple choice technology testing
  1. Which technique is appropriate to test changes on old and undocumented functionalities of a system?

  1. Specification based technique

  2. Black box technique

  3. White box technique

  4. D. Data driven testing technique
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

White box testing examines the internal structure and implementation of the system, making it appropriate for testing undocumented legacy code. When specifications are unavailable, analyzing the code structure helps identify test scenarios and verify that the existing functionality works correctly, even without formal requirements documentation.

Multiple choice technology testing
  1. By creating future tests based on the results of previous tests, a tester is demonstrating at type of informal test design technique?

  1. Security testing

  2. Non functional testing

  3. Exploratory testing

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

Exploratory testing is an informal approach where testers design and execute tests simultaneously, using insights from previous test results to guide subsequent testing. This adaptive, learning-based approach allows testers to investigate the system dynamically and follow promising leads based on what they discover.

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

One of the fields on a form contains a text box which accepts numeric values in the range of 18 to 25. Identify the invalid Equivalence class

  1. 17

  2. 19

  3. 24

  4. 21
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

For a valid range of 18-25, the equivalence classes are: valid (18-25), invalid below (less than 18), and invalid above (greater than 25). Option A (17) is invalid because it's below the minimum valid value of 18. Options B (19), C (24), and D (21) are all valid values within the accepted range.

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.

Multiple choice technology testing

Exploratory technique comes under which test approach?

  1. Consultative Approach

  2. Preventive Approach

  3. Dynamic Approach

  4. Model Based Approach
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Exploratory technique comes under the Dynamic Approach because it involves simultaneous learning, test design, and execution - all dynamic activities. Model Based Approach uses predefined models, Consultative Approach relies on expert input, and Preventive Approach focuses on prevention.

When processing a For loop or iterating over a Value List or Page List, which standard parameter would you inspect to get the value of the current iteration?

  1. pyIterationNumber

  2. pyForEach

  3. pyForEachCount

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

During loop execution over a list, Pega automatically stores the current iteration index in the standard parameter pyForEachCount. The other parameters like pyIterationNumber, pyForEach, and pyCount do not exist as standard loop counters in Pega's engine API, making them incorrect.
