Non-Functional Testing

Non-functional testing is a type of software testing that checks the behavior of the system under specific conditions. It is aimed at assessing the performance, reliability, and security of the system. Non-functional testing comes in two general categories: black box testing and white box testing.

Types of Black Box Non-Functional Testing

Black box non-functional testing is done without any knowledge of the internal workings of the system. This type of testing is focused on the system's behavior rather than its implementation. Here are some common types of black box non-functional testing:

1. Performance Testing

Performance testing is a type of testing that checks how a system responds to a particular set of conditions. It includes load testing, stress testing, and capacity testing. The goal of performance testing is to ensure that the system can handle a particular load within acceptable parameters.

2. Usability Testing

Usability testing is a type of testing that evaluates a system's user interface and user experience. It checks how easy it is for users to operate the system, the clarity of instructions, and how good the system's feedback is.

3. Security Testing

Security testing is a type of testing that checks the system's security features, access controls, and authentication measures. The goal of security testing is to identify potential threats and vulnerabilities that could compromise the system's security.

4. Compatibility Testing

Compatibility testing is a type of testing that ensures that the system can work effectively with different types of hardware, software, and operating systems. This type of testing is typically done on web applications to ensure that they work on different browsers and mobile devices.

Explanation

Black box non-functional testing is a type of testing that focuses on the system's behavior and performance without the knowledge of the system's internal workings. It includes performance testing, usability testing, security testing, and compatibility testing, and is aimed at assessing the system's performance, reliability, and security.

Use

Black box non-functional testing is used to ensure that the system behaves and performs effectively under different types of conditions. It helps to assess the quality and reliability of the software and enables developers to identify potential issues before launching the product.

Important Points

• Black box testing is done without any knowledge of the system's internal workings.
• Non-functional testing is aimed at assessing the performance, reliability, and security of the system.
• Performance testing is important to identify performance bottlenecks and ensure that the system can handle the load.
• Usability testing is important to ensure that the system is easy to use.
• Security testing is important to identify potential vulnerabilities and threats that could compromise the system's security.
• Compatibility testing is important to ensure that the system can work effectively with different types of hardware, software, and operating systems.

Summary

In conclusion, black box non-functional testing is a type of testing that focuses on the behavior and performance of the system without the knowledge of the system's internal workings. It includes performance testing, usability testing, security testing, and compatibility testing and is aimed at assessing the system's performance, reliability, and security. It is important in identifying potential issues before launching the product and ensuring that the system behaves and performs effectively under different types of conditions.
