Non Functional Testing Guide to Characteristics,Types,Requirements

Here’s why functional and non-functional app testing are complementary ways to ensure end user satisfaction. When you perform testing, you focus more on functional testing to test the product functionality. We need what is non-functional testing to consider the testing requirements right from the start of the project. This type of testing concerns testing the system readiness per different non-functional parameters unaddressed by functional testing.

Creating a Requirement Traceability Matrix is one way you can ensure all business requirements are tested, whether by automation tools or your testing team. By making this combination part of your QA strategy, you will ensure that you discover more software bugs and cover more testing bases. 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. You can carry out integration testing in large projects using automated frameworks that automatically build test cases. Programmers may use automated testing tools such as Behat, Cucumber, or RSpec.

Comparison of Functional and Nonfunctional Testing

Scalability testing can, therefore, be considered one form of non-functional testing method to guarantee the system’s scalable quality. It is a sort of non-functional test which is carried out to assess the capacity of the software or system to be modified without problems in order to satisfy the evolving requirements of the customer. Browse our favorite online non-functional testing resources below or read the answers to some of the most frequently asked questions about non-functional testing. If you want to find out more about non-functional testing, there are lots of FAQs and resources available online. If you’re new to non-functional testing, you may think that you can just dive right into the testing stage without creating a thorough test plan in advance.

It is performed in an integrated hardware and software environment to ensure that the entire system functions properly. Performing compatibility testing requires diverse environments, like different browsers, devices, and operating systems. Testing tools like NeoLoad have full tech-stack support that enables users to test a wide range of mobile, web, and desktop applications.

Example Test Cases Non-Functional Testing

The above list is not the complete as there are more than 100 Types of Testingand counting. No need to worry, you will pick them up as you age in the testing industry. Also, note that not all testing types apply to all projects but depend on the nature & scope of the project.

• While developers also work with code-based testing, developers usually focus more on creating earlier-stage unit and acceptance tests.
• Volume testing is a type of testing that exists to verify what happens when large volumes of data are added to the database at once.
• Portability is important because it affects how easily end users can manage software and move it between different systems.
• It also checks to see if the entire system is working fine with the novel changes.
• For unit testing, you create a checklist that tests each unit of code against a specific scenario.

It gives the ability to record when you edit the script and allows you to get the test results after execution. It has an in-built engine that allows concurrent virtual users to perform stress tests. It allows you to see your website’s https://globalcloudteam.com/ performance and scalability, reducing risk and maximizing the benefits of your next high-traffic event. Non functional testing, on the other hand, checks the broader quality concerns and verifies all non functional aspects.

For Developers

For Performance Testing, a well-structured and clear specification about expected speed must be defined. The parameter determines the degree to which user can depend on the system during its operation. Improve and enhance knowledge of the product behavior and technologies in use. Collect and produce measurements, and metrics for internal research and development. Optimize the way product is installed, setup, executes, managed and monitored. Recovery tests determine how quickly software can rebound after a crash or failure.

Most of the time, the servers might be unavailable or busy, thanks to heavy load. The best example is a college website where exam results are obtained. Continuous quality cloud platform like LambdaTest lets you perform cross browser compatibility testing of your websites and web applications across 3000+ real browsers, devices, and operating systems. With its real device cloud, you can test applications in real-world scenarios and get accurate results. Non-functional testing examines how well the product works and increases the usability of the product. Overall, non-functional testing tests everything else functional testing doesn’t.

How Do I Pick a Tool For Non-Functional Testing?

Load tests check the software’s viability under different defined loads, from normal to peak conditions. This testing determines how much work the software can handle before performance degrades. For example, you can run multiple applications simultaneously, subject the server to heavy traffic, or download many files simultaneously. You can use various non-functional testing methods to understand software quality, including testing its performance, usability, and reliability. Of course, functional and non-functional testing cannot be clearly distinguished.

Endurance capability to work under multifarious conditions, circumstances, and workloads. Note down the run state to know if it’s at normal, failure, peak load, or latency stage. Security is a fundamental feature through which you can protect your system from malware or cyber-attacks. Create awareness of the product behavior and technologies we need to use.

Why do you need Non-Functional Testing?

The main goal is to ensure relationship integrity and data flow among different parts or units operating together. The usability testing part of a testing methodology looks at the end-user usability aspect of the software. In other words, the ease with which a user can access the product forms the main testing point. Usability testing looks at five aspects of testing — learnability, efficiency, satisfaction, memorability, and errors.

Without a clear test plan, it’s easy to lose sight of the scope and aims of the tests that you’re performing. This type of testing is important because systems without proper recovery protocols could suffer serious data losses when accidents like this occur. Portability testing is used to test how flexibly the software can be transferred from its current hardware or software environment, and how easy this is to do. The availability of the software refers to the degree to which the user can depend on the system during its operation.

Functional Testing

Test cases are conducted by finding areas of code where an attack is most likely to happen. The measurement and metrics used for internal research and development are collected and produced under non-functional testing. Few systems perform the same in responding to one request per second as they do to 10,000 requests per second. Load testing validates that a system can handle peak loads and fail gracefully when it lacks the resources to handle workload spikes. You don’t want to have to go into multiple different tools to view the results of your testing. And manually tracking the results in a spreadsheet is likely to introduce human error.
