Automation can certainly reduce time and effort in executing functional tests. Human error can also be lowered, preventing bugs from slipping past the test phase. Firstly, you should understand the project specification and the app architecture.
The tool must be easy to use, especially for all members of your QA team. These tests uncover discrepancies that might not have been identified in any of the other tests. Ad-hoc tests are targeted towards breaking the system and checking its response. If correct credentials are entered but the user wants to cancel login, the system should not direct to the home page UI.
Unlike non-functional testing, functional testing isn’t concerned with investigating the quality, security, or performance of the application’s underlying source code. Sahi is an open source functional automation testing tool which provides support for testing web applications. Sahi is easy to understand and its the main concept is to support record and playback any web application, on any operating system. Sahi provides limited functionality as compared to other tools. Smoke testing is another types of functional testing in which developer test the basic functionality of the build.
Durability– Durability is the measure of the ability of the application to cater to the requirements for a long period of time. Usability– Usability is defined as the measure of the degree to which an application can be easily used and operated. For example, in the case of a new application, the easier the flow of the application is for the user to operate it smoothly, the better will be the usability.
By performing stress testing, testers determine the limit at which the software product breaks. Moreover, it helps them to analyze what the system will do after failure. The primary purpose of this type of testing is to verify the readiness of the software product in accordance with non-functional parameters thatfunctional testingwould never address. One simple example of a non-functional test would be checking how many users can log in to a particular system simultaneously. The best way to sum up the difference between functional and non-function testing is functional testing shows that the application’s functions are doing what they’re supposed to do. In contrast, non-function testing verifies that the software conducts the processes correctly.
Naturally, formulating the right test case is pivotal, along with identifying the right automation tool for the purpose. If incorrect credentials are entered, the system should inform the user and reload the login page. These tests are used to check how the system behaves when data limits are implemented.

Test Case Examples of Non-Functional Testing
To put it simply, functional requirements are the features that the end-users want in the software product. On the other hand, non-functional requirements are the quality constraints that the system should satisfy as per the project contract. Functional testing can be an arduous, repetitive, and time-consuming process.
Here in this article, we have discussed the various types of non functional testing. It is designed to test the readiness of system bas per non functional parameters which are never addressed by functional testing. Volume testing refers to testing a software application, where the software is subjected to a huge volume of data.
It is a form of testing that is used to determine the stability of a given system. The goal of such type of testing to ensure the software does not crash in conditions of insufficient computational resources. The primary goal of acceptance testing is to test whether software system has met the requirements or not. Acceptance testing is done by the user or by the client. A system may be required to present the user with a display of the number of records in a database.
Usability testing checks the degree of ease with which the end-users can learn, operate, and interact with the software product. Moreover, this type of testing is equally important as functional testing. The reason is that end-users always want a high-performance, secure, and scalable software product having rich functionalities.
How to write Nunit Parameterized Test
These tests are initiated to check for possible system outcomes when a particular condition is met. In the example, since the user id requires a minimum of 6 characters, this test will be used to check how the system responds when less than 6 characters are entered. When successful, the login page directs the user to the HRMS home page. An online HRMS portal on which the user logs in with their user account and password.
API testing is a type of software testing that validates application program interfaces for their functionality, security, performance, and reliability. Reliability testing checks for the reliability of the system. In other words, this type of testing checks how the software product works in a particular environment for a specific time period. The system is reliable only if it produces the expected results every time in the given environment. Performance testing validates the software product to check how well its components function.
Example: Use Case Scenario for Functional Testing
Non-functional testing is the testing of “how well” the system behaves. NeoLoad is yet another powerful performance testing tool for definition of non-functional testing large enterprises. It is capable of carrying out performance testing on various types of APIs, applications, and other technologies.
- Sahi is easy to understand and its the main concept is to support record and playback any web application, on any operating system.
- Create input data for functionalities to be tested according to specified requirements.
- The non functional tests can be effective by using testing tools.
- So today, we’re discussing testing, specifically non-functional testing.
- Basically, Neoload works by simulating the network traffic to examine the performance of the system under load.
- Performance– Performance is a non-functional requirement that deals with the measure of the response time of the application under different load conditions.
- Non functional testing focus on the quality of the software system.
Optimize how the software product gets installed, set up, managed, and monitored. To what extent can a user depend on the system while operating? This parameter defines how well a system is protected from sudden and deliberate attacks from within and without. Performance Testing eliminates the reason behind the slow and limited performance of the software.
Our AI-Powered, Intelligent Automated Functional Testing Tools Can Help
If the system gives expected output, it gets passed in the test otherwise failed. The flexibility of software to transfer from its current hardware or software environment. How to write Nunit Parameterized Test Learn about different types of NUnit Parameterized Tests with help of examples and sample code. With BrowserStack, this problem is solved by offering the ability to run hundreds of Selenium and Cypress tests in parallel.
Other types of Testing
The more you automate, the faster you can ensure desired functionality or identify and correct defects, and the more you save on test time and costs. It may not be possible, or even desirable, to automate all test cases, but just getting the most important test cases off the manual roster can vastly improve your test ROI. Non functional testing focus on the quality of the software system. So tries to deduce how well the system performs as per the customer requirements means nonfunctional testing helps verify that customer expectations are being met or not.

Process Workflow for Functional Testing
All the cool concepts and nifty “bells and whistles” in the world mean nothing if the application fails to work correctly. That’s why developers need to put a new product through its paces before the public gets a hold of it. Security testing is used to detect the security flaws of the software application. The testing is done via investigating system architecture and the mindset of an attacker. Test cases are conducted by finding areas of code where an attack is most likely to happen.
Scalability– Scalability is defined as the ability of the system to cater to the growing usage of the application. This tool comes with an IDE that can seamlessly integrate with development environments. The LoadRunner Professional Engine enables testers to run unit tests. It ensures the loading capability of the system so that any number of users can use it simultaneously. The portability testing of the software is used to verify whether the system can run on different operating systems without occurring any bug.
