Question 5Which of the following is non-functional testing?1 pointblack box testingwhite box testingperformance testingunit testingintegration testing

1. Break Down the Problem

We need to identify which of the provided testing types is considered non-functional testing. The options provided are:

1. Black box testing
2. White box testing
3. Performance testing
4. Unit testing
5. Integration testing

2. Relevant Concepts

• Functional testing: This type of testing verifies that the software functions as intended, focusing on specific requirements or functionalities.
• Non-functional testing: This involves testing the software's performance, usability, and reliability, without focusing on specific functionalities.

3. Analysis and Detail

1. Black box testing: Generally considered a functional testing method, as it tests the software's features without knowing the internal workings.
2. White box testing: Also functional testing, involves testing internal structures or workings of an application.
3. Performance testing: This is a non-functional testing method focused on evaluating the speed, scalability, and stability of the system.
4. Unit testing: A form of functional testing that assesses individual components of the software for correctness.
5. Integration testing: Primarily functional testing, ensures that combined components or systems work together properly.

4. Verify and Summarize

Among the given options, only performance testing is a non-functional testing type. The others focus on verifying functionalities and internal workings.

Final Answer

The non-functional testing type from the list is performance testing.
