Why Software Testing is Essential for Developing Software

Software testing is a crucial element in the development of software. If you're working on a team that develops or maintains the software, then it's likely that part of your responsibilities will involve testing software.

The testing process separates the good quality software products from bad quality software applications/products which are not fit enough to run well in a production environment.

Quality issues detected during testing phases should be fixed immediately. It helps businesses improve their brand image and customer satisfaction by delivering the best possible quality products/services.

What is Software Testing?

A software testing procedure to verify whether the actual software product meets expected standards and that it is free of bugs. It includes manually or automatically executing system components to assess one or more of those properties that are important.

Software testing is a process of finding mistakes, gaps, and missing requirements in relation to real-world conditions. The key element of today's software development is learning through a Software Testing Online Course. It ensures that the produced code is free of bugs by correctly utilizing various approaches and tools.

Some Main Types of Software Testing

Software testing can be conducted at different levels depending on the requirement specification and nature of the system to be tested. The main types of testing are Unit testing, Module (Integration) testing, System Testing, Acceptance Testing and Regression Testing.

Unit Testing: This is the first and most granular level of testing and ensures that an individual unit of source code is working correctly. A unit could be a method, class, module or component.

Integration Testing: At this stage, individual components are combined and evaluated as a whole to ensure that they function properly. It is done after unit testing and before system testing.

System Testing: This is the level where the software product/system is tested to validate if it works as per its specifications from an end-user perspective.

Acceptance Testing: Also known as functional testing or alpha testing, acceptance testing of a software product ensures that specified requirements are met. Acceptance testing is conducted by the end-user or customer of the software product to validate that the developed system satisfies its business requirements.

Regression Testing: It is done as a retesting and involves retesting the previously tested program after making any changes to the code/program to ensure that modifications have not affected other parts of the program.

Automated vs Manual Software Testing

FITA Academy guides you to understand that Software testing is an essential aspect of software development. It helps the business stakeholders and end-users to identify defects in newly developed or upgraded software products/applications before they are released into the production environment for use by the general public.

While some software testing can be automated using available tools, manual software testing cannot be completely replaced. Manual testing is still required in the areas where automation tools cannot provide desired results.

For example, some applications need to test on mobile devices with no automation tools due to their proprietary technology stacks and APIs. The other primary reason why testers prefer manual testing over automation is its cost-effectiveness. Automation testing requires costly and skilled resources to maintain the testing tools.


Software testing is essential because it reduces the risk involved in delivering new products/applications to market. It also increases customer satisfaction by giving them good quality products as expected from your company.

Software Testing Course in Chennai teaches how to understand the requirements, design test strategies and write detailed test cases for an application under test, which mainly covers functional and non-functional requirements.

The course also helps you learn different techniques the professionals use while analyzing the defects from bug reports generated from executing the Test Case using bug tracking tools.
