Software Testing and Quality Control Questions

Multiple choice technology testing

Testing to determine whether a product or system meets some specified standard that has been developed for efficiency or interoperability

  1. Compatability testing

  2. Compliance testing

  3. Interoperability testing

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

Compliance testing (also called conformance testing) specifically determines whether a product meets specified standards for efficiency, interoperability, or other defined criteria. Compatibility testing checks if the system works with different platforms/environments, interoperability testing tests interaction between systems, and performance testing measures speed. Compliance testing is the correct match for 'meeting specified standards'.

Multiple choice technology testing

Testing that involves observing the people using the product to discover errors and areas of improvement

  1. Soak testing

  2. Scalability tetsing

  3. Usability testing

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

Usability testing specifically involves observing real users using the product to discover errors and areas for improvement. It focuses on the user experience, ease of use, and user satisfaction. Soak testing tests longevity, scalability testing tests ability to scale up, and acceptance testing determines if requirements are met. Usability testing directly matches 'observing people using the product to discover errors and improvements'. Option B also has a typo 'tetsing' instead of 'testing'.

Multiple choice technology testing

While an application is running, suddenly restart the computer, and afterwards check the validness of the application's data integrity This comes under which type of testing?

  1. Recovery testing

  2. Reliability testing

  3. Performance testing

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

Recovery testing specifically tests how well a system recovers from crashes, failures, or unexpected conditions like sudden restarts. It verifies that data integrity is maintained and the system can properly restore itself after crashes. The scenario describes exactly what recovery testing is - restart the computer while application is running, then check data integrity. Reliability, performance, and load testing don't focus on crash recovery scenarios.

Multiple choice technology testing

Excessive volume in terms of either users or data,examples might include a denial of service (DoS) attack or a situation where a widely viewed news item prompts a large number of users to visit a Web site during a three-minute period This comes under which type of testing?

  1. Load testing

  2. Stress testing

  3. Performance testing

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

Stress testing tests systems under extreme or excessive loads beyond normal operating conditions. The scenario describes excessive volume - either DoS attacks or sudden massive traffic surges (widely viewed news item causing traffic spikes). These are extreme conditions beyond normal expected load. Load testing tests under expected loads, performance testing measures speed, and recovery testing tests crash recovery. Stress testing is specifically designed for these excessive overload scenarios.

Multiple choice technology testing

Testing response time measures of a web page at various levels of load, eg 500 users, 750 users and 1,000 users. This comes under which type of testing?

  1. Load testing

  2. Stress testing

  3. Performance testing

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

Load testing specifically tests system behavior under expected user loads by measuring response times at various load levels (500, 750, 1000 users as mentioned). The key characteristic is testing at SPECIFIC increasing load levels and measuring response. Stress testing tests beyond normal load, performance testing is broader, and reliability testing focuses on consistency. Load testing with its graduated load measurement perfectly matches 'testing response time at various levels of load'.

Multiple choice technology testing

Ergonomics testing tests

  1. User friendliness

  2. whether important information is presented in a comprehensible way

  3. Only A

  4. A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ergonomics testing (or HCI testing) encompasses both user friendliness (ease of use, intuitiveness) AND whether important information is presented comprehensibly. Option A covers user friendliness, Option B covers information comprehensibility. Since ergonomics testing includes BOTH aspects, 'A and B' is the correct answer. Only A (Option C) is incomplete, and individual options A or B capture only half of what ergonomics testing evaluates.

Multiple choice technology testing

Process of putting demand on a system and measuring its response is

  1. volume testing

  2. Stress testing

  3. Load testing

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

Load testing is the process of applying demand to a system and measuring its response under expected or normal conditions. Volume testing focuses on data volume, stress testing pushes beyond capacity, and performance testing is the broader category that includes load testing.

Multiple choice technology testing

Form of testing that's used to determine the stability of a given system is

  1. Recovery testing

  2. Load testing

  3. Reliability testing

  4. Stress testing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Stress testing determines system stability by pushing it beyond normal operating conditions to identify breaking points. Recovery testing checks recovery after failures, load testing measures response under expected demand, and reliability testing focuses on consistent performance over time.

Multiple choice technology testing

  1. Compatability testing

  2. Compliance testing

  3. Reliability testing

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

Compliance testing verifies that a product meets specified standards for efficiency, interoperability, or other defined criteria. Compatibility testing checks if systems work together, reliability testing measures consistent performance, and performance testing measures speed.

  1. Soak testing

  2. Scalability tetsing

  3. Usability testing

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

Usability testing involves observing real users interacting with a product to identify errors, usability issues, and improvement opportunities. Soak testing tests for memory leaks over time, scalability testing handles growth, and acceptance testing validates requirements.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Recovery testing verifies that a system can recover from failures and maintain data integrity after unexpected events like system restarts. Reliability testing focuses on consistent performance, performance testing measures speed, and load testing applies expected demand.
