Functional Testing is a type of software testing in which the system is tested against the functional requirements. It tests all the aspects which are not tested in functional testing. Exact numbers are unlikely to be known at the start of the requirement process. Non-functional testing should increase usability, efficiency, maintainability, and portability of the product. Ramp testing comes under performance testing. Performance Testing . While functional testing emphasizes the quality and reliability of the code, it is more of a development perspective. Do all the web images have alt tags?. Lets get things started with a definition. Non-functional software testing is the process of evaluating a software system or application to ensure that it meets the non-functional requirements set for it. What is non functional testing types with example? 1. Endurance testing is a type of non-functional testing that is used to measure the amount of time that a software application or system can be operated without experiencing any failures. Compatibility testing can be performed on individual components or on an entire system. Testing must be done in a way that accurately reflects real-world conditions. Regression Testing:This test verifies that recent updates or changes havent impacted the apps existing functionality. This allows the tester to determine how the system will respond under varying conditions. To help in reduction of cost related with non-functional aspects of the product. It helps to ensure that the applications released to users are reliable and meet their expectations. (Exception is Usability Testing where black box testing method is used. We conduct non-functional testing to make sure that the interests of the end-user are respected. Maintenance testing. Recovery Testing: Recovery testing is a type of non functional testing which is used to verify the ability of software to recover from failures like software or hardware crash, network failure, disk failure, etc. Some of the most frequently-used tools for functional software checkups are Selenium, UFT, SoapUI, IBM Rational Functional Tester, Postman, Apache JMeter, Test Complete, and Katalon Studio. What is Non-Functional Testing? It helps in covering all the aspects which are not covered under functional testing. To what extent can an application expand (or contract!) This is contrast to functional testing, which tests against functional requirements that describe the functions of a system and its components. Endurance testing is a type of non-functional testing that is used to determine how long a software application will last under heavy usage. Stress Testing:It pushes a system or component up to or beyond its specified requirement limits. No need to worry, you will pick them up as you age in the testing industry. This is in contrast to Functional Testing which focuses on features / functional requirements. Thats why developers need to put a new product through its paces before the public gets a hold of it. If not, that would be called a regression.. Changes that may require regression testing include bug fixes, software enhancements, configuration changes, and even substitution of electronic . 3. By verifying that the software meets the required standards, compliance testing can help to ensure that the software functions as expected and does not pose a risk to users or to the organization. This type of testing is important because different platforms have different hardware and software configurations, which can affect how the software performs. It describes how the product does. Volume Testing:Confirms that a program can handle the values that can potentially grow over time (e.g., accumulated counts, logs, and data files) and the build-up will not crash the program or degrade its operation in any way. Non-functional testing is testing designed to check a software application's non-functional aspects such as performance, reliability, utility, etc. Also, note that not all testing types apply to all projects but depend on the nature & scope of the project. These tests find issues in software design and architecture performance. . Documentation Testing: Evaluates the products user manuals and related documents. This parameter ensures that the software system keeps functioning and recovers itself in the event of system failure. This can be accomplished by identifying and fixing defects that cause the test to take longer than it should, or by finding ways to reduce the number of required tests. Non-Functional Testing is defined as a type of Software testing to check non-functional aspects (performance, usability, reliability, etc) of a software application. Optimize the way product is installed, setup, executes, managed and monitored. Its main goal is to determine whether software operations will going to performed to well after the failure of the data or software . So today, were discussing testing, specifically non-functional testing. Scalability: Non-Functional testing checks the ability of a system to meet the increased demand by expanding its processing capacity. Non-functional Testing is a method of software testing that examines a software application's non-functional attributes (productivity, compatibility, functionality, and many more). This article discusses and defines non-functional testing, how it is performed and offers a roundup and links to tools that . Volume testing is a type of non-functional testing that involves testing how much data can be processed by an application. Only if every feature of a software system works correctly, it can pass a functional test. From testing the load capabilities and performance metrics of an app to checking compatibility, security, and localization of the product, there are countless non-functional software testing types that deal with every . Non-functional Testing :Inforgraphics: Nonfunctional aspects of software testing comprises of the ways in which one can ensure that a software meets the software requirements as well as delivers beyond expectations of the end users. Performance tests may measure how long software takes to complete a task, the number of errors made, or the time it takes to access data. On other hand during Non-Functional testing is the testing in which the performance or usability and behaviour of software/application is done under different circumstances. of a . Non-functional software testing is the process of evaluating a software system or application to ensure that it meets the non-functional requirements set for it. It is designed to test the readiness of a system as per nonfunctional parameters which are never addressed by functional testing. Failover Testing:Verifies that, in the event of a system failure, the system has sufficient capabilities to handle extra resources such as servers. The name comes from the fact that you ramp up the test conditions (speed, volume, etc.) Non Functional testing is essential for confirming . Non-functional testing focuses on user expectations, whereas functional testing is to do with user requirements. Regression testing (rarely, non-regression testing) is re-running functional and non-functional tests to ensure that previously developed and tested software still performs as expected after a change. Efficiency testing is the process of measuring how much work a system can perform in a given time period. The parameter defines how a system is safeguarded against deliberate and sudden attacks from internal and external sources. Another type of non-functional testing, compatibility testing verifies the compatibility of the application or product with different computing environments. 4. This type of testing is used to ensure that a system can recover from these events in a timely manner and without causing further damage. The capacity of the application to endure a load is referred to as stability. The goal of localization testing is to ensure that all text within the application is properly translated and displayed and that all functionality works as expected regardless of the users language. This parameter defines how well a system is protected from sudden and deliberate attacks from within and without. Recovery testing can also help to ensure that the system is able to recover from future failures. Compatibility testing is a process of verifying the compatibility of hardware or software with other hardware or software, operating systems, devices, and other environments. Broadly, non-functional testing covers all aspects not covered in functional testing - factors not related directly to the software's functions. Memory leaks, database server utilization, and unresponsive system are common issues examined by endurance testing. Black-box testing is a type of testing where the tester does not have access to the inner workings of the software. There are several different ways to test for failover. It involves conducting tests with real users to determine how well the product or service meets their needs. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Software testing is never just limited to testing just a software's functions as there are other elements that also need to be tested. Reliability testing is a type of non-functional testing that checks the reliability of a system if the system is reliable to use. Toggle navigation. It is designed to test the readiness of a system as per nonfunctional parameters which are never addressed by functional testing. This form of testing is performed according to customer expectations based on the required app performance. Efficiency testing is a type of non-functional testing that focuses on identifying and reducing the amount of time needed to complete a software test. This is checked by Interoperability Testing. Load testing helps the tester determine how the application functions under the normal workload and excessive workload. Heres a small sample of the different available functional testing strategies (also referred to as types): Although these two testing methods occasionally overlap to one extent or the other, they have two distinct functions and check for different things. For example, a non-functional test may test how well a program operates at a higher scale or how the system performs when run for a long period. Compliance testing can be performed on a variety of levels, from checking specific requirements against the code to verifying that the system meets regulatory requirements. This type of testing is important to ensure that a product is intuitive and meets the needs of the target audience. Functional testing is performed before the application goes live. The goal is to purposefully find loopholes and security risks in the system that could result in unauthorized access to or the loss of information by probing the application for weaknesses. The goal is to make changes to the product based on feedback before releasing it to the public. It covers all the areas that are not covered . This type of testing is often used in conjunction with other types of testing like stress and load testing to ensure that the software meets customer expectations. Functional testing is based on customer's requirements whereas Non . You may find some difference in the above classification in different books and reference materials. Stability testing is an important part of the software development process. With non functional testing, enterprises can validate . In simple words, non-functional testing focuses on validating non-functional aspects of the software (reliability, performance, etc.) The above list is not the complete as there are more than 100 Types of Testing and counting. Closed-box Testing:Also referred to as "black box testing," it focuses on the application's externally visible behavior and outputs, not the software's inner workings. Non-functional testing checks the integrity of non-functional aspects of the software - performance, usability, reliability, security, etc. Stress testing is a type of non-functional testing that is used to assess the resilience of a system or application under conditions that are outside the normal operating environment. You then need to select an appropriate test scenario and set up your testing environment. Endurance testing can be used to evaluate the durability of a product, as well as its ability to withstand repeated use. Non functional testing tools have evolved to a great extent because of demand in the market. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. John Terra lives in Nashua, New Hampshire and has been writing freelance since 1986. Non-functional testing is defined as a type of software testing to check non-functional aspects of a software application. It is an important part of software development and is often done in conjunction with penetration testing and vulnerability assessment. You can also use software that will automatically shut down systems or applications in the event of a failure. Scalability testing is a critical part of any software development project. Functional testing focuses on the functionality of the software, while non-functional testing focuses on aspects such as performance and stability.
