What is Non-functional Testing?

Non-functional testing is a type of testing used to evaluate the performance, usability, reliability, and other failures of a software application. Software Requirements Specifications (SRS) form the basis of this software testing and allow the quality assurance team to check whether the system meets the customer’s requirements. Improving the usability, performance, security, and portability of products are the goals of non-functional testing. It helps reduce production risk associated with product failure. The overall quality and dependability of software products are greatly improved by non-functional testing, which also protects data integrity and improves user experience....

What are the Types of Non-functional Testing?

Performance Testing: Performance testing eliminates the cause of slow software and poor performance. The software should be read as quickly as possible. A good and clear plan should be created to ensure the urgency of performance evaluation. Otherwise, it will not be clear whether the test is successful or unsuccessful. Load Test: During the load test, the capacity of the system is tested. Due to its load capacity, the system can handle multiple users simultaneously. Tools that are used in load testing are Neoload and Load Multiplier. Portability Testing: The software has been tested for portability based on its ability to run error-free across multiple operating systems. This test also tested the functionality of the software on different devices with the same operating system. Tools that are used include SQLMap. Reliability Testing: This test assumes that the software system operates without errors according to predefined parameters. To operate the system, certain periods and procedures must be used. Reliability tests may fail if the system does not operate under certain conditions. Recovery Testing: Recovery testing evaluates an application’s ability to recover from crashes, hardware failures, and other similar problems. Countermeasures involve deliberately attacking the software through various means. Tools used in recovery testing are Box Backup and Bacula. Volume Testing: A type of software testing called volume testing which involves exposing software to large numbers of files. This is also called flood testing. By adding information to the database, measurements can be made to evaluate the effectiveness of the system. Tools include HammerDB and JdbcSlim. Responsive Testing: Responsive testing allows you to test your design on different screen widths for its adaptability rather than screen width. Tools that are used include Operator, Screenfly, and Google DevTools....

Best Practices for Non-functional Testing

Test Automation: Leverage test automation tools and frameworks to simplify and speed up defect testing. Automation helps simulate customer loads, create consistent test data, and perform repetitive tasks, enabling more efficient and reliable testing. Assessment and Performance Evaluation: Use powerful monitoring tools during testing to capture performance metrics such as response time, resource usage, throughput, and error rate. These measurements provide insight into behavior, help identify conflicts, and facilitate performance evaluation. Risk-Based Testing: Before failure testing based on risk assessment and business impact. Focus on critical operations, high-risk areas, and situations that could lead to poor performance, poor security, or potential problems. Clear Target: Define clear and measurable goals for failure testing. Set specific goals related to performance, security, usability, and other parameters to guide testing and provide a basis for evaluation. Real-word Test Environment: Create real-world tests that mimic the production environment. Use representative hardware, software, network configuration, and data storage to provide performance and behavior analysis....

Conclusion

Non-functional testing is a great way to make sure your app is optimized for user experience and meets the required standards. It helps developers identify and resolve potential issues before their apps are released to the general public. This reduces the risk of failure and ensures that the application meets the customer’s needs....
