vnext global an overview of software testing

Software testing is a technique aiming at determining if the actual software product meets expectations and is error-free. It involves manual or automation tools to execute software/system components in order to assess attributes. Software testing, in general, aims to find flaws, gaps, or unmet requirements. Written by VNEXT Global, a company providing software testing services, this article will identify testing definition, benefits, approaches, types and levels.


What Is Software Testing?

Software testing is a procedure to assess a software application's functioning with the aim of determining if the developed software matches the required specifications or not. Software testing also uncover any bugs to guarantee that the product is free of errors and produces a high-quality result.

What Are Benefits Of Software Testing?

  • Cost saving: Timely testing of any IT project enables you to make long-term financial savings. The sooner flaws are found in the software testing process, the less expensive fixing them is.
  • Security: This perilous and delicate advantage of software testing. People are seeking dependable items. It assists in minimizing errors and issues early.
  • Product quality: Testing guarantees that buyers receive a high-quality product: error-free, short-loading time, etc.
  • Customer satisfaction: The primary goal of every product is to provide consumers with satisfaction. The optimum user experience is made sure of user-friendly UI/UX testing.

2 Software Testing Approaches?


Manual Testing

The practice of manual testing is done to discover what is and isn't working. As a result, all team members can understand more about the software product.


This often entails checking all the functionality listed in the requirements documentation, but it also frequently involves the testers examining the product while the end users are also using it.


The types of manual test plans can be completely scripted test cases that provide testers with specific instructions and expected outcomes, or high-level directives that direct exploratory testing sessions.


Here are Top 4 Manual Testing Tools Suggested By VNEXT Global.


Automation Testing

The process of testing software with an automated tool in order to detect bugs is known as automation testing.


In this procedure, testers use automation technologies to run the test scripts and provide the test results automatically.


Selenium and Katalon Studio are two well-known automation testing technologies for functional testing.


Here are Top 5 Automation Testing Frameworks Suggested By Senior Automation Testers.

2 Software Testing Types


Functional Testing

Generally speaking, functional testing is the process of testing whether all software functions meet requirement specification or not. Testing each functionality by supplying the proper input will allow you to determine whether or not the output produced matches requirements.


Non-functional Testing

Non-functional testing refers to how well the system operates. Non-functional testing covers a variety of software-related topics, including usability testing, compatibility testing and performance testing. The primary goal is to enhance how quickly a user receives a response from the system.

4 Software Testing Levels


Unit Testing

Software testing that is done on a single unit or component to test any adjustments is known as unit testing. Unit testing is often carried out by the developer throughout the application development process. Each unit tested during unit testing can be thought of as an object, function, method, or process. For the execution of tests, developers frequently use test automation tools like NUnit, Xunit, and JUnit.


Because we may uncover more flaws at the unit test level, unit testing is crucial.


There is a straightforward calculator application, for instance. The tester can carry out the unit test to check if the user can enter two numbers and receive the correct sum for additional functionality.


Integration Testing

Integration testing" involves logically grouping together two or more modules of an application and testing them as a whole. This sort of testing focuses on identifying interface, communication, and data flow flaws between modules. When integrating modules into the overall system, either a top-down or bottom-up strategy is utilized.


This kind of testing is carried out while integrating modules into one system or another. A user may purchase a flight ticket from any airline website, for instance. While purchasing a ticket, users can view payment and flight information, although both are handled by separate systems. When connecting an airline website with a payment processing system, integration testing should be carried out.

System Testing

System testing is a sort of testing where the entire system is assessed in comparison to the given requirements.


System testing entails putting a whole application environment through its paces in a scenario that simulates actual use, such as communicating over a network, connecting with a database, or, if necessary, integrating with other hardware, software, or systems.


For example, a tester is evaluating a website for pet insurance. Purchasing an insurance policy, tag, adding a new pet, changing payment card information on users' accounts, updating user address information, receiving order confirmation emails, and receiving policy paperwork are all examples of end-to-end testing.


Acceptance Testing

In acceptance testing, real-time business scenarios are used to evaluate the software. Clients, businesses, or customers can participate in this stage.


Only after all the features and capabilities behave as intended, the clients accept the software product. This is the final stage of testing before the software is launched. Therefore, another name for acceptance testing is user acceptance testing (UAT).


Final thought

Play a crucial role in every software development project, software testing should be carefully concerned. A proper testing strategy can bring high-quality software products, cut down cost and time, and optimize security for the business.
