What is Software Testing and why it is required ?

Software testing is a process that is followed in development and maintenance of software application. It involves assessing the quality, functionality, and performance of a software application to identify any defects, bugs, or errors.

The objective of software testing is to make sure the software application meets the received requirements, functions as intended, and delivers a good user experience.

Software testing majorly classified into two categories:

1. Functional Testing – which mainly focuses on functionality validation and making sure it meets the             requirement.

     Ex : Unit Testing, Smoke Testing, System Testing, Integration Testing, User Acceptance Testing.

2. Non-Functional Testing – which focuses on non-functional aspects like performance, security, resiliency of software application.

    Ex : Performance Testing, Security Testing, Fail-over Testing, Compatibility Testing.

Why Software Testing required ?

To answer this question, Software is developed by developers based on the requirement received. Once the application is developed, it is essential to check whether the system is working is as per requirement received. Also, there is high chance of human errors during application development life cycle, hence testing engineers who are well versed with software testing is preferred in current industry.
