Up till now, you must have seen separate articles for Functional Testing and Non-Functional testing. In any case, in today’s article we will see the real distinction between Functional Testing and Non-Functional Testing.

Difference Between Functional Testing and Non-
Functional Testing
What do you mean by non functional testing?
The non functional Testing is the kind of testing done
against the non functional needs. The vast majority of the
criteria are not considered in functional testing so it is
utilized to check the availability of a system

Non Fuctional Testing
Non functional testing affects client and client satisfaction
with the product. Non functional testing is expected to be
told in a testable manner “the software should be fast” or
“the software ought to be easy to operate” which is not
testable.

Cont.....
The testing of software properties which are not identified with
a particular function or client activity like execution,
adaptability, security or behavior pattern of application under
specific limitations.

Non Functional Testing Types

Load testing

Reliability testing

Performance testing

Security testing

Volume testing

Installation testing

Localization testing and internationalization testing

Recovery testing

Stress testing and many more……

Five stages required to remember in case of Functional
testing:

Arrangement of test data in light of the requirements of the
function.

Business necessities are the inputs to functional testing.

In light of functional specifications, discover of output of the
functions.

Executing the test cases.

Watch the actual and expected results.

Following types of testing need to be covered
under functional testing

Sanity testing

System testing

Integration testing

Smoke testing

Regression testing

User Acceptance testing etc..

Functionality testing involves checking the following

Installation and setup on localized systems running
localized operating systems and pages with local
code.

Content handling, (for example, copying, pasting,
and altering) of augmented characters,
extraordinary textual styles, and non-Latin scripts.

String taking care of, content, and information,
particularly when interfacing with non-Unicode
applications or modules.

This document provides an overview of performance and load testing basics. It defines key terms like throughput, response time, and tuning. It explains the difference between performance, load, and stress testing. Performance testing is done to evaluate system speed, throughput, and utilization in comparison to other versions or products. Load testing exercises the system under heavy loads to identify problems, while stress testing tries to break the system. Performance testing should occur during design, development, and deployment phases to ensure system meets expectations under load. Key transactions like high frequency, mission critical, read, and update transactions should be tested. The testing process involves planning, recording test scripts, modifying scripts, executing tests, monitoring tests, and analyzing results.

Software testing & Quality Assurance Webtech Learning

Software testing is an important phase of the software development process that evaluates the functionality and quality of a software application. It involves executing a program or system with the intent of finding errors. Some key points: - Software testing is needed to identify defects, ensure customer satisfaction, and deliver high quality products with lower maintenance costs. - It is important for different stakeholders like developers, testers, managers, and end users to work together throughout the testing process. - There are various types of testing like unit testing, integration testing, system testing, and different methodologies like manual and automated testing. Proper documentation is also important. - Testing helps improve the overall quality of software but can never prove that there

Testing concepts pptRathna Priya

Testing involves finding errors in a program. The goal is to assume a program contains errors and test to find as many as possible. Different testing techniques include white box testing by developers and black box testing by testers. Testing levels include unit, integration, system, and user acceptance testing. Developers and testers have different goals - developers want code to work while testers try to make code fail. Good development practices from a tester's view include doing own acceptance tests, fixing bugs, writing helpful error messages, and not artificially adding bugs. Good relationships between project managers, developers and testers help ensure quality.

Load testing involves systematically stressing a system or application to determine its behavior and stability under different load conditions. There are different types of load tests that can be run depending on the test goals. It is important to measure key metrics like response times, failures, and system resource usage during a load test to understand the system's performance limits and how it degrades as load increases. Load test results should indicate the maximum number of users the system can support while meeting performance requirements as well as insights into how the system will perform as usage grows over time.

A test case is a set of conditions or variables under which a tester will determine whether a software system is working correctly. Test cases are often written as test scripts and collected into test suites. Characteristics of good test cases include being simple, clear, concise, complete, non-redundant, and having a reasonable probability of catching errors. Test cases should be developed to verify specific requirements or designs and include both positive and negative cases.

ENASE 2013 - SEM - (Francia) From Functional Test Scripts to Performance Test...Federico Toledo

When modernizing systems the software is migrated from one platform to another. There are big risks concerning the performance the system should have in the new platform. A new system cannot take more time to perform the same operations than the previous one as the users will refuse it. Therefore, the preventive performance test is crucial to guarantee the success of the modernization project. However, the automation tasks for performance testing are too demanding, in terms of time and effort, as the tools work at a communication protocol level. Though not free, the functional testing automation is easier to accomplish than the performance testing automation as the tools work at a graphic user interface level; the tools are therefore more intuitive and they have to handle less variables and technical issues. In this article we present a tool that we developed for industrial usage to automatically generate performance tests scripts from automated functional tests. The tool has been used in several projects in the industry, achieving important effort savings and improving flexibility.

Functional Testing- All you need to know (2).pptxJason Roy

Software testing that verifies a software system or application's functionality is known as functional testing. Its main goal is to guarantee that the system functions in a way that satisfies the anticipated business demands and conforms to the functional criteria. Validating the system's features, capabilities, and interactions with various components is the aim of functional testing. It entails testing the system's reaction to various scenarios and settings, user interactions, data manipulation, and input and output of the software. The sole goal of functional testing is to confirm that a system functions as intended.

Software testingSengu Msc

Testing is the process of evaluating a system or its components to identify differences between expected and actual results. It involves executing a system to identify gaps, errors, or missing requirements. There are different types of testing such as unit testing, integration testing, system testing, and acceptance testing. Testing can be manual, automated, functional, or non-functional. Functional testing evaluates system functionality while non-functional testing evaluates attributes like performance and security. Common non-functional test types are load testing and stress testing which analyze a system's behavior under different load conditions.

Performance testing ensures that a software system performs well under expected workloads over time by testing aspects like response time, speed, scalability, and stability. It is done to identify bottlenecks and limitations so they can be addressed before public release. There are different types of performance testing like load testing, stress testing, endurance testing and volume testing that evaluate how an application handles different types and levels of usage. The performance testing process involves planning tests, setting up environments, executing tests, verifying results, and retesting as needed.
