Non Functional Testing With Non Functional Test Examples

We hope this article helped you in understanding the non-functional testing concept. For any query or suggestion, please let us know in the comments and we will try to answer at the earliest. The portability testing of the software is used to verify whether the system can run on different operating systems without occurring any bug. This test also tests the working of software when there is a same operating system but different hardware. Non-functional testing is also very important as functional testing because it plays a crucial role in customer satisfaction. To help in the reduction of production risk related with non-functional aspects of the product.

Functional and Non-Functional Testing Checklist Here is a detailed checklist for functional testing and non-functional testing requirements. Quality assurance is the backbone of trust and credibility that companies build with their customers. By prioritizing quality and investing in robust QA processes, you can ensure that your products consistently meet high standards of performance, reliability, and security. Following TDD, developers construct tests before writing the actual code. This ensures that the software is built with testing in mind from the start, i.e., programming follows a set of testing objectives, thus enhancing its quality. With user expectations rising and security concerns multiplying, software performance and cyber resilience are critical.

Non-Functional Testing Parameters

Reliability test assumes that whether the software system is running without fail under specified conditions or not. The system must be run for a specific time and number of processes. If the system is failed under these specified conditions, reliability test will be failed. For example, non-functional testing would be to test how many people can work simultaneously on any software. We’ve mentioned functional testing already but haven’t taken any time to define it. This parameter covers how easy it is for the application to work with different hardware and software configurations, such as CPU and RAM requirements.

It is wise to incorporate security testing and treat it with the same seriousness as unit testing. Additionally, functional tests can be run on more than 3000+ real browsers and devices. Device, browser, or OS fragmentation is no longer a concern, as BrowserStack facilitates testing in real user conditions on both desktop and mobile devices. The goal of functional testing is to validate the system’s features, capabilities, and interactions with different components. It involves testing the software’s input and output, data manipulation, user interactions, and the system’s response to various scenarios and conditions. Functional testing is only concerned with validating if a system works as intended.

Usability Testing

Robust demand for coders is more significant than ever, so if you want a secure, rewarding career in this growing field, Simplilearn can provide you with a strong https://www.globalcloudteam.com/ start. These are the eleven parameters found in non-functional testing. Of course, there may be occasions where not all of them are brought into play.

Later, QA specialists cover these objectives in more detail, creating checklists and test cases to break them down. In a way, checklists and test cases instruct how to achieve the set objectives and the ultimate goal of software testing by taking small steps. Software is commonly designed to work in conjunction with other systems, devices, or platforms.

Testing Objectives and Testing Types

In the planning stages, every project creates a document listing functional or requirement specifications. Essentially, it is a list of what the app/system/website is supposed to do from a user’s perspective. Implementation should occur in a way that will allow several learning cycles to determine the right level of NFRs.The structure of an ART can also impact the implementation of NFRs.

• Repeat the steps involved in the dataset, configuration, request load, and scenario.
• If incorrect credentials are entered, the system should inform the user and reload the login page.
• These are not part of the features a user can see but more about the reliability factor of the application.
• Situations of misunderstanding between clients and team members could lead to an increase in overall project time.
• Collection and production of metrics and measurements to cater to internal research and development.

But, we cannot forget how important non-functional testing is. We need to consider the testing requirements right from the start of the project. Non-functional testing can improve the product’s reliability, performance, manageability, and accessibility.

Why do you need Non-Functional Testing?

Non-functional testing is a critical part of any testing strategy. In these cases, critical tests don’t run in time to fully guarantee the delivery readiness of upcoming releases. Endurance testing — Tests an app under a heavy load over an extended period of time.

The portfolio backlog may also require NFRs, typically for cross-solution qualities . Agile Teams use Built-In Quality practices to accelerate NFR testing and make it continuous. Teams include the relevant NFRs in their DoD, use them as constraints on local design and implementation decisions, and take responsibility what is non-functional testing for NFR testing. Record everything that’s needed, be it response time or throughput. Note down the run state to know if it’s at normal, failure, peak load, or latency stage. Ensure that your test environment consists of the same production environment setup, be it configuration, mentoring, or physical architecture.

Example Test Cases Non-Functional Testing

In this article, we discussed the difference between functional and non-functional testing. Functional testing comprises test cases that validate the application’s core features. NFRs are in quadrant 4 of the Agile testing matrixDue to their considerable scope and tooling requirements, testing NFRs may require the help of the System Team. Since any system changes can violate conformance with NFRs, these tests must be run continuously, or at least whenever it’s practical. To support this built-in quality, teams should automate testing NFRs to run continuously with other tests or on demand when needed. Quadrant 4 of the Agile Testing Matrix in Figure 7 outlines system quality tests to verify the system meets its NFRs.

Moreover, it will be time-consuming and desired results might not be achieved. Using some tool that performs automated tests is an effective and time-saving option. Thus, there are some automation tools available in the market for the same. Security testing is one of the most crucial testing types of non-functional testing. In this type of testing, the system’s readiness to fight back against any external or internal attacks is tested.

Difference between Functional Testing and Non Functional Testing

The objectives of testing get more specific when we apply the concept to a specific project. Every time, test objectives will be slightly different and suited precisely for the case. The objectives of regression testing are to check software for defects after code alterations and learn whether these alterations have affected the stable features.
