What Is Non Functional Testing? An Overview
Non-functional testing metrics describe those metrics by which the performance and efficiency of the system are measured. Error messages should also occur during security testing when the system prevents https://globalcloudteam.com/ users from breaching the software’s in-built security features. When you’re carrying out non-functional testing, you’ll receive different types of outputs from the tests that you perform.
Localization testing verifies the application works well in different locales. Localization testing aims to test the content and graphical user interface of the application and determine if it is ideal for a specific region or not. Scalability testing can be considered a form of non functional testing that guarantees the application’s scalable quality. It’s a part of the non functional trials group to evaluate the application’s efficiency by increasing the information volume. The volume may generally be the size of a volume-tested file interface or a database.
Compared to other testing procedures, there is a smaller overall time commitment. Improving the installation, configuration, execution, management, what is non-functional testing and product monitoring. Efficiency test examines the number of resources needed to develop a software system, and how many of these were used.

The first stage of the life cycle for non-functional testing is the analysis of software requirements. Software teams work towards specific criteria when they’re building and testing applications, and these criteria should dictate what type of tests need to be carried out. Nonfunctional testing involves measuring the performance or reliability of a system. Security tests test how resilient the system is against malicious attacks. Integration tests stress-test a system’s design, behavior, and performance by testing its components together. Besides ensuring that previous changes have their intended effects, integration tests also help identify any issues with parallel changes to other parts of the system.
Confidentiality, integrity, authentication, and authorization are the main areas tested under this type of non-functional testing. In non-functional testing more than other types of testing, it’s important to use automation tools to automate certain types of testing, specifically volume testing, stress testing, and load testing. The difference between functional and non-functional testing is in what they test. Functional testing tests the functions of the application and checks whether they work as expected.
For example, the purpose of reliability testing is not to test whether the app functions but to test whether the app functions reliably on repeated attempts. For example, you might find that the system doesn’t load quickly enough under certain conditions or even crashes if too many users log in at the same time. Once the test results are in, hand the software back to developers if tests failed or if you identified any non-functional bugs that need fixing. Without a clear test plan, it’s easy to lose sight of the scope and aims of the tests that you’re performing. Set up the testing environment before you start non-functional testing.
Non-functional testing readiness checks
You can easily enhance the application behavior.You can easily improve the application performance. You can easily execute manual functional testing.It’s tough to perform non-functional testing manually. You get to test what the product does.You get to test how the product does what it does. Functional testing helps assess business requirements.Non-functional testing helps assess the performance requirement.
Functional testing is based on customers’ requirements, while the other is based on customers’ expectations. Modern businesses clearly differentiate between the requirements and expectations of customers. Non functional testing has become non-negotiable after the growing emphasis on customers’ expectations. If you’re new to this field or want an in-depth look at non functional testing and how it can apply to the products you develop, keep reading.
What’s the Difference Between Functional and Nonfunctional Testing?
Optimization of how you install, set up, manage, execute and monitor the product. Detection of product behavior problems under simulation of different operations. A creative content writer having over four years of experience in digital marketing. An Engineering graduate with experience in website creation, content development, social media marketing, and copywriting. Checking if the navigation within the product is clear and easy to use. If not, it might be difficult to determine if the test was a success or failure.
It is too rigid to say that the functional method is better than non-functional or the other way around. As they advance up the pyramid, developers implement lower volumes of methods like integration testing and then progress toward practices like user acceptance testing at the end. Eventually, they top the pyramid more sparingly with testing methods that offer lower returns relative to their implementation costs. Unit tests for an API application might make requests against the system deployed in a testing environment and compare the responses against documentation. When the application deviates or regresses in functionality, application-wide functional tests often detect changes that unit tests don’t.
The aim is to measure and assess the behavior, response, and effectiveness of an application. It is related to the testing of applications subjected to elevated data volumes. It is the simplest form of performance testing, and it is carried out under a specified predicted load condition to understand the application behavior. Performance testing is a subset of efficiency engineering, ensuring that applications are performed effectively under the anticipated load. Under functional testing, you may test if the username and password allow users to log in to the application. However, under non functional testing, you check if the user can log in to the application within 3 seconds of providing a username and password.
- Further, this testing assesses a system’s readiness for non-functional parameters that aren’t typically addressed in functional testing.
- Examples of non-functional testing include testing designed to assess capacity, performance, usability, recovery, and portability.
- To perform a functional test, I also select a checking, savings or investment account in the banking app.
- Non-functional tests should be measurable, so no subjective characterization such as good, better, nicer, etc., are available.
- The purpose of this type of testing is to make sure that new users can easily install the software on their machines and existing users can upgrade it when new upgrades are released.
- It is designed to test the readiness of a system as per nonfunctional parameters which are never addressed by functional testing.

SonarQube is an open-source security testing tool that can automatically analyze code to detect bugs and vulnerabilities. These types of testing usually verify how well software operates under heavy pressure from users, data, and traffic, which can be very difficult conditions to emulate manually. As with other types of testing, non-functional testing is usually carried out using a mixture of manual testing and automated testing.
