It’s important that systems display accurate and clear error messages when errors do occur so that users can take steps to correct the problem and continue using the software. This makes it easier for testers to ascertain whether the software meets these requirements during testing and leaves no room for interpretation. This reduces the risk of small mistakes that could cause serious delays in the testing and development process.

Non Functional testers would check if the dashboard can load within 2 seconds. Non-functional testing is how we test the properties of the application that doesn’t form a critical base for functionality. The approach document before you conduct non-functional testing has to cover the test scope, test metrics, testing tools, important dates, and deliverables. Even though this testing doesn’t impact the business directly on the functionality aspects, you can amplify the user-friendliness and user experience to the next level. 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.

Compatibility Testing

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. Make sure that the loading capability of the system is intact when the ‘n’ number of users leverage it simultaneously.

This checks whether applications recover gracefully when inputs are not as expected or when the environment fails. For instance, when a user types an invalid input that causes a database process to abort, or when systems shut down abnormally due to a power failure, and so on. Functional and non-functional requirements testing are examples of black box testing. This means that testers do not require advanced technical skills or knowledge of computer programming to carry out black box testing, nor do they need to learn how to implement the systems they’re testing. ZAPTEST is a popular software testing tool that allows users to carry out both functional and non-functional software tests quickly and easily. You can use ZAPTEST to automate software tests and utilize RPA technology to emulate various functions and conditions in non-functional testing.

Load Testing

Functional testing is performed before your application goes live.Non-functional testing includes tests such as maintainability and documentation, which happen after testing. Non-functional testing verifies the way software works and how well it works. There are several non-functional testing types, including performance testing, load testing, stress tests, volume tests, security tests, upgrade and installation testing, and recovery tests.

Portability testing helps test if the software can run on different operating systems without any issues. The functionality of the product under the same platform but with different hardware will also be tested. The team focuses on testing software through different software testing technology after the software development process has been completed.

The life-cycle of non-functional tests

One way to address this complexity is to use a sophisticated testing tool like Selenium. These tools allow code to interact with an application https://globalcloudteam.com/ as if it were a user in a web browser. Selenium and tools like it automate user acceptance testing while increasing reliability and scaling up.

• Verify that the 500 users can log in to the application simultaneously.
• On clicking the red camera icon, you can easily find the visual differences as Testsigma highlights them for easy identification.
• You can run it repeatedly to ensure the correct operation of individual components like functions and methods.
• See how Perfecto can help you ratchet up your non-functional testing and boost your testing strategy.
• The measurement and metrics used for internal research and development are collected and produced under non-functional testing.

It is essential, as such attacks are highly critical and enable a hacker to capture server database data. Maintenance tests are used to assess the software application’s ability to readily be upgraded or altered to satisfy increasing user needs and requirements. Compatibility testing performed at the early phases of quality assurance allows the team to ensure that customer-requested compatibility criteria are met and integrated with the final product.

7. System Testing

Interactions between modules are frequently the points where errors occur. Functional testing often includes testing portions of the underlying code. Your team’s testing practice should assess the entire application, observe the larger story of how it operates when functioning correctly, and raise alarms when deviations are found. The word was first discovered in the 1979 Arts of Software Testing by ‘ Glenford Meyers, ‘ which describes volume testing as ‘ Subjecting the program to a deep amount of information. Ensure that in software engineering, quality characteristics are properly recognized. Non-functional tests should be measurable, so no subjective characterization such as good, better, nicer, etc., are available.

Test implementation is an incredibly critical factor in the software development process, from being a component of all tests to recognizing multiple defects, bugs, and problems within the scheme. The team of testers can produce a product that meets the demands of the customer and provides a certain service with the help of this method. So, in this article, we have seen What is Non functional Testing, Characteristics of Non functional Testing along with its types and requirements. As the name suggests, it concentrates on an application’s non-functional aspects such as performance, usability, security, compatibility, and all other aspects that are not tested under functional testing. Non-functional testing is performed to verify these NFRs and if the system’s behavior is in accordance with them. Loadium is a non-functional testing tool that’s best used to carry out performance testing and load testing, two types of non-functional testing that are much easier to carry out using automation tools.

Functional vs non-functional software testing

As a QA tester, I develop and execute test cases that exercise user authentication. To perform a functional test, I also select a checking, savings or investment account in the banking app. Then, I transfer money between each type of account in varying denominations. These are all actions a target user will take in the application, expecting the sums to be accurate each time.

It emphasizes monitoring the modification and adjustment of the production environment to meet the specific users’ requirements of those who leverage goods in that particular region. Compatibility testing lets you validate if the application or product is compatible with different devices, browsers, and operating systems, all at widely different configuration strengths. It verifies the behavior of an application at different load conditions. Tests non functional aspects, such as reliability, usability, and performance.

Increase the user-friendliness of the software

Loadrunner is a set of tools that help you run performance tests smoothly. These tests are performed to determine the response time, behavior, and overall performance of an application. LoadRunner is one of the most widely used performance testing tools because it consumes minimal hardware what is non-functional testing resources and is extremely efficient. Functional testing verifies that the application is working as intended. On the other hand, non-functional testing checks how well the application works in terms of efficiency, performance, security, scalability, reliability, and portability.
