Need of Non-Functional Testing

What is Non-Functional Testing?

Furthermore, we perform non-functional testing to check various aspects of an application, such as performance, usability, reliability, and more. Additionally, we specifically design non-functional testing to evaluate an application’s readiness based on non-functional parameters that functional testing does not address.

An excellent example of a non-functional test is to check how many people can use the application simultaneously.

Need of Non-Functional Testing

• Non-functional testing is done to increase usability, efficiency, maintainability, and portability of the application.
• Helps to reduce production risk and cost related to non-functional features of the application.
• Enhance the way product is installed, setup, executes, managed, and monitored.
• Gather and provide measurements and metrics for internal research and development.
• Improve knowledge of the product behavior and technologies in use.

Features of Non-Functional Testing

• Non-functional testing should be quantifiable so that there is no scope for subjective characterization like good, better, best, etc.
• Exact numbers are unexpected to be known at the initial phase of the requirement process
• Important to prioritize the requirements
• Make sure that quality features are recognized correctly in Software Engineering.

Non-Functional Testing Parameters

• Security: The parameter defines how an application is protected against attacks from internal and external sources.
• Reliability: Performed to test the limit of the software until it continuously performs the specified functions without failure.
• Survivability: The parameter checks that the software application can recover itself from system failure.
• Availability: This determines the degree to which the user can depend on the application during its operation.
• Usability: This check if the user can operate the application easily or not.
• Scalability: The term refers to the degree to which any software application can expand its processing capacity to meet an increase in demand.
• Interoperability: This parameter checks software system interfaces with other software systems.
• Efficiency: The extent to which a software application can handles capacity, quantity, and response time.
• Flexibility: The refers to the ease with which the application can work in a different environment like hardware and software configurations. Like minimum RAM, CPU requirements.
• Portability: The ability of software to convert from its current hardware or software environment.
• Reusability: It refers to a feature of the software application that can be used in another application.

Type of Software Testing

Below are the main Categories of Testing Types:

• Functional Testing
• Non -Functional Testing
• Maintenance Testing

Types of Non-functional Testing

Following are different types of Non-Functional Testing:

Compatibility Testing

 his testing is done to check if an application is working as expected on different platforms, OS, Devices, software, and hardware.

Configuration Testing

 We perform configuration testing to ensure that the final product works smoothly with supported and different software and hardware configurations.

Compliance Testing

Additionally, we perform compliance testing, also known as conformance testing, to check if the application is functioning and performing according to the company’s established standards and guidelines. Furthermore, this testing ensures that the application meets the required regulatory and industry standards, providing assurance of its compliance with specified criteria.

Installation Testing

Moreover, we perform implementation testing, also known as “installation testing,” to evaluate that there are no issues during the process of software installation, upgrades, and uninstallation. Additionally, this testing helps ensure a smooth and error-free installation process, identify any compatibility issues, and verify that the software can be upgraded and uninstalled without causing any disruptions or data loss.

Documentation Testing

Furthermore, to investigate the documentation artifacts prepared before and during the software development and testing phase, we perform documentation testing. This includes various requirements, specifications, plans, strategies, and other related and tangible elements. Moreover, this testing ensures the accuracy, completeness, and consistency of the documentation, helping to identify any gaps, errors, or discrepancies that may impact the software development and testing process.

Load Testing:

We perform this testing to check the application’s behavior and response under various load factors.

Endurance Testing

This testing is done to check if the application can support under a massive expected load over a long period of time.

Localization and Internationalization Testing

To check is application is working as expected in different languages, locale, etc.

Performance Testing

We perform this testing to test the response, stability, scalability, reliability, and other quality metrics of a software application.

Maintainability Testing

We perform this testing to check the upgrade/modified capability of an application, ensuring it meets the growing needs and requirements of the users.

Recovery Testing

We perform this testing to validate the recovery capability of an application from crashes or failures.

Security Testing

We perform Security Testing to validate the security features of the application and protect the data from unauthorized access.

Reliability Testing

Software reliability gives a measure of the product’s life cycle between two failures and its repair time.

Volume Testing

In volume testing, we load the application with a huge amount of data to measure and evaluate the response, behavior, and effectiveness of the application.

Scalability Testing

Scalability testing ensures that the application should be scalable, in proportion to an increase in the load, number of concurrent users, data size, etc. whenever required.

Usability Testing

 We perform this testing to evaluate that the end-user can access and understand the application easily.

Stress Testing

Stress testing evaluates the robustness of software by testing beyond the limits of normal operation.
