What is Non-Functional Requirements (NFR) Testing?

Non-Functional Requirements (NFR) Testing is the process of evaluating how well a software product meets the non-functional aspects of user requirements. These non-functional aspects are the qualities that make a product desirable, such as how fast it runs, how secure it is, how easy it is to use, and how reliable it is.

Think about it this way: if you were buying a car, you wouldn’t just care about how fast it can go or how it looks, right? You’d also care about its safety features, how comfortable it is to ride, and how fuel-efficient it is. The same goes for software. Non-functional requirements are the characteristics that can make or break the user’s experience with the product.

NFR Testing is essential to ensure that a software product meets the user’s expectations and performs as intended. It’s like putting the product through its paces to see if it can handle the user’s demands. So, whether you’re developing a game, an app, or any other type of software, NFR Testing is a crucial part of ensuring that the product delivers the best possible experience to the user.

Importance of NFR testing in Software Development

Non-functional requirements (NFR) testing is a critical aspect of software development that should never be overlooked. It plays a significant role in ensuring that software products meet the user’s expectations in terms of performance, security, and usability. Without proper NFR testing, software products may fail to meet the user’s expectations, leading to dissatisfaction, negative reviews, and even loss of business.

Let’s consider the example of a mobile banking app. The speed and usability of the app are critical factors that make or break the user’s experience. If the app takes too long to load, customers may switch to another app that loads faster and is more user-friendly. Furthermore, if the app is not secure, it can pose a significant risk to users’ sensitive financial information, leading to mistrust and a damaged reputation for the banking institution.

This is where NFR testing comes in. Performance testing can ensure that the app loads quickly and operates smoothly, providing a seamless experience for the user. Usability testing can ensure that the interface is user-friendly and intuitive, making it easier for users to navigate the app. Security testing can ensure that users’ data is protected from potential threats, mitigating the risks of data breaches.

In short, NFR testing is crucial to ensuring that software products deliver the best possible experience to the user. As an expert, we strongly recommend that software developers prioritize NFR testing to identify and address any potential issues early on. By doing so, developers can create software products that users love and continue to use for years to come.

Examples of NFR testing using Selenium Automation Testing

Test Case #1 “Application load time should not be more than 5 secs up to 1000 users accessing it simultaneously” – falls under the domain of Performance Testing, which is a type of non-functional testing. Performance testing is the process of testing software applications or systems to measure how well they perform under various workload conditions.

In this particular test case, the objective is to ensure that the application’s response time is within acceptable limits when 1000 users access it simultaneously. The maximum response time set in this case is 5 seconds. This test case helps to identify performance bottlenecks, such as issues with database queries, network latency, server hardware, or software configuration, that could impact the application’s performance under heavy load. By conducting performance testing, software teams can ensure that their applications are optimized for speed, scalability, and reliability and can handle large user volumes without degrading performance.

Test Case #2 – “Software should be installable on all versions of Windows and Mac” – falls under Compatibility Testing, another type of non-functional testing. Compatibility testing is the process of testing software applications or systems to ensure that they are compatible with various operating systems, devices, browsers, and hardware configurations.

In this particular test case, the objective is to ensure that the software can be installed and run successfully on all versions of Windows and Mac operating systems. This test case helps to identify compatibility issues, such as issues with software dependencies, system requirements, file formats, or user permissions, that could prevent the software from functioning correctly on specific platforms or configurations. By conducting compatibility testing, software teams can ensure that their applications are compatible with a wide range of environments, reducing the risk of application failures, errors, or crashes and improving the user experience.

Test Case #3 – “All web images should have alt tags” – falls under the domain of Accessibility testing, a type of non-functional testing. Accessibility testing is the process of examining a software application or system to ensure that people with disabilities or special needs can use it.

In the context of web applications, images that lack alt tags can pose significant accessibility challenges for users with visual impairments, as they rely on screen readers to interpret web content. Alt tags describe the image, which the screen reader can read out loud to the user, allowing them to understand the context and meaning of the image. Therefore, testing that all web images have alt tags is an essential part of accessibility testing, as it ensures that users with visual impairments can fully access and navigate the application.

In summary, accessibility testing is an essential aspect of non-functional testing, which seeks to ensure that software applications and systems are accessible and usable by individuals with disabilities or special needs. It covers a variety of areas, including but not limited to font size, color contrast, keyboard navigation, screen reader compatibility, and image descriptions, among others.

Best Practices for NFR Testing using Selenium Automation Testing

1. Be proactive and Agile with your testing approach

Being Agile means being proactive and taking action early on. This practice is particularly true when it comes to testing for non-functional requirements (NFRs). It’s essential to plan for NFR testing from the beginning of a project, as NFRs can significantly impact the coding and architecture of your application.

Imagine you have an NFR that requires your application to handle high traffic of 1000 requests per second. By starting NFR testing from the beginning of the project, you can identify early on whether your application architecture can handle this requirement. This may lead to making changes to the code or design or adopting new coding practices to achieve the desired outcome. For instance, you might use thread pools to reduce the time it takes to make and spawn new threads or utilize multi-casting and aggregation patterns to achieve better response times.

Another NFR could require the system to avoid overloading in the event of a component failure. Once again, by testing this NFR from the beginning, you can determine whether your system can handle this requirement. You can build your application to fail fast in case of an error using the Hystrix circuit breaker from Netflix.

Early and Agile NFR testing can help verify your application’s coding approach and architecture. LambdaTest can assist in NFR testing by providing a cloud-based digital experience testing platform that enables you to perform real-time and automation testing on your web applications across 3000+ browsers and devices. With LambdaTest, you can easily test for performance, load, scalability, and compatibility.

LambdaTest can help you with NFR testing by providing you with a comprehensive testing platform that allows you to test for various non-functional requirements. By utilizing LambdaTest, you can identify any potential issues early in the development cycle and take proactive steps to ensure that your application meets the desired NFRs.

2. Test environment setup

When conducting NFR testing, it’s essential to set up the right environment to get accurate results. The environment should closely mimic the production environment in terms of configuration, physical architecture, and monitoring. If any of these factors deviate from the production environment, your test results may be skewed and less reliable when presented to stakeholders.

For example, let’s say your NFR requires your system to handle 100 transactions per second. If you set up your test environment with 2 CPUs and four cores, but the production environment has four and eight cores, the test results could go one of two ways. You may get good results and see that your code is optimized and works well on limited hardware. On the other hand, you may get bad results and think there’s something wrong with your application when it’s just a hardware limitation. This can lead to wasting time and resources on optimizing already optimized code.

Conversely, if you set up a test environment with better hardware than the production environment, you may get a false sense of security. This can be dangerous as you won’t know how your application will perform in the production environment. To ensure accurate and reliable results, it’s crucial to set up a prod-like environment for your NFR testing.

When it comes to non-functional requirements (NFR) testing, it is essential to set up the proper environment to ensure accurate and valid results. As mentioned, the NFR test environment must be as close as possible to the production environment regarding configuration, data, platform, and monitoring. Any deviation from the production environment can skew the results and cast doubt on the validity of the test.

LambdaTest can also assist in setting up the proper NFR testing environment. With LambdaTest, you can easily spin up various virtual machines with numerous configurations, operating systems, and browsers to mimic the production environment accurately. This allows you to perform NFR testing under real-world conditions and obtain accurate and valid results.

In addition, LambdaTest provides advanced monitoring capabilities, enabling you to monitor your application’s performance during NFR testing closely. With LambdaTest, you can easily monitor key performance indicators (KPIs) such as response time, latency, and error rate. This data can help you identify bottlenecks and areas for optimization, allowing you to ensure that your application meets the desired NFRs.

Overall, LambdaTest can be an invaluable tool for NFR testing, helping you to set up the proper environment, monitor key performance indicators, and obtain accurate and valid results.
