What are different types of non-functional tests

                                                     

Non-functional testing plays a vital role in software testing by examining the non-functional characteristics of a software application. In contrast to functional testing, which checks if the software executes its intended tasks accurately, non-functional testing evaluates the software's performance under different conditions. This encompasses aspects such as performance, scalability, reliability, usability, and security, among other factors.

OBJECTIVES OF NON-FUNCTIONAL TEST

§  The goals of non-functional testing include enhancing the usability, efficiency, maintainability, and portability of the product.

§  It aims to minimize production risks and costs related to the non-functional features of the product. Additionally, it seeks to optimize the installation, setup, execution, management, and monitoring processes of the product.

§  Non-functional testing also involves gathering and producing measurements and metrics for internal research and development purposes.

§  Ultimately, it contributes to a better understanding of the product's behaviour and the technologies employed.

 

CHARACTERISTICS OF NON-FUNCTIONAL TEST

 

§  Non-functional testing must be measurable. As such, terms like “good,” “better,” and “best” are not appropriate in this context.

§  It’s unlikely that precise numbers will be available at the start of the requirements process.

§  Prioritizing the requirements is essential.

§  Additionally, it’s important to ensure that quality attributes in software engineering are clearly defined.

 

NON-FUNCTIONAL TEST TYPES

Non-functional testing examines various aspects such as performance, security, usability, and reliability to ensure the software's overall effectiveness. Each type of non-functional test plays a distinct role in enhancing different facets of the software, contributing to its success in the market. Now, let’s focus on the types of non-functional testing.

 

1. Performance Testing:

 This measures the software’s responsiveness, speed, and efficiency under different conditions.

 2. Load Testing:

 Load testing evaluates the system’s ability to handle specific loads, ensuring proper performance during peak usage.

 3. Security Testing:

 This identifies vulnerabilities, protecting the software against security threats and breaches, including the leakage of sensitive data.

 4. Portability Testing:

 This assesses the software's adaptability across various platforms and environments.

 5. Compatibility Testing:

 Compatibility testing ensures smooth functionality across multiple devices, browsers, and operating systems.

 6. Usability Testing:

 To improve the software’s usability, this type of testing focuses on the user interface, navigation, and overall user experience.

 7. Reliability Testing:

 Reliability testing assures the software’s stability and dependability under both normal and abnormal conditions.

 8. Efficiency Testing:

 This evaluates resource utilization to ensure optimal performance while using minimal resources.

 9. Volume Testing:

 This tests the system’s ability to handle large amounts of data that are regularly fed into the system.

 10. Recovery Testing:

 To ensure data integrity and system stability, recovery testing assesses the software’s ability to recover from various failures.

 11. Responsiveness Testing:

 Responsiveness testing evaluates how quickly the system reacts to inputs.

 12. Stress Testing:

 This type of testing pushes the system beyond its normal capacity.

 

CONCLUSION

 In summary, non-functional testing offers a thorough assessment of an application’s performance, reliability, and user experience. By focusing on factors like scalability, security, and usability, these tests ensure that the software can effectively manage real-world situations. This comprehensive approach to testing ultimately results in more robust, secure, and user-friendly applications, which enhances overall customer satisfaction and trust.
