Introduction to Software Testing :
Software testing can be stated as the process of verifying and validating whether a software or application is bug-free, meets the technical requirements as guided by its design and development, and meets the user requirements effectively and efficiently by handling all the exceptional and boundary cases.
The process of software testing aims not only at finding faults in the existing software but also at finding measures to improve the software in terms of efficiency, accuracy, and usability. It mainly aims at measuring the specification, functionality, and performance of a software program or application.
Software testing can be divided into two steps:
Verification: it refers to the set of tasks that ensure that the software correctly implements a specific function.
Validation: it refers to a different set of tasks that ensure that the software that has been built is traceable to customer requirements.
Verification: “Are we building the product right?”
Validation: “Are we building the right product?”
What are the different types of software testing?
Software Testing can be broadly classified into two types:
- Manual Testing: Manual testing includes testing software manually, i.e., without using any automation tool or any script. In this type, the tester takes over the role of an end-user and tests the software to identify any unexpected behaviour or bug. There are different stages for manual testing such as unit testing, integration testing, system testing, and user acceptance testing.
Testers use test plans, test cases, or test scenarios to test software to ensure the completeness of testing. Manual testing also includes exploratory testing, as testers explore the software to identify errors in it.
- Automation Testing: Automation testing, which is also known as Test Automation, is when the tester writes scripts and uses another software to test the product. This process involves the automation of a manual process. Automation Testing is used to re-run the test scenarios quickly and repeatedly, that were performed manually in manual testing.
Apart from regression testing, automation testing is also used to test the application from a load, performance, and stress point of view. It increases the test coverage, improves accuracy, and saves time and money when compared to manual testing

Conclusion:
Software testing is an indispensable part of the software development process, ensuring that applications meet quality standards and perform optimally. In the dynamic world of technology, where software is constantly evolving, effective testing practices are essential to deliver reliable and secure software to end-users. By adopting a systematic and comprehensive approach to testing, development teams can build and maintain software that not only meets but exceeds user expectations in the ever-changing digital landscape.
