What is Software Testing?

        Software testing is the process of evaluating a software program or system to identify any gaps, errors, or missing requirements, and to ensure that it meets the requirements that guided its design and development. Testing is performed to uncover bugs and issues that would affect the software's performance, stability, and security. It is usually conducted by the software development team, but can also be done by users and independent testers. Depending on the type of software being tested, tests can include unit tests, system tests, integration tests, performance tests, security tests, and more. 

What is SDLC?

        SDLC (Software Development Life Cycle) is a process used to develop a software application in any IT industry. In software companies, the whole team have to follow the SDLC process. Where different approach comes in figures, such as Waterfall Model, Iterative, Spiral, Lean and Agile. Agile is one of the most common and used by industry experts to develop any software. Because in Agile methodology, the team can break down a big project into smaller parts and work simultaneously. We will cover Agile methodology in a separate tutorial deeply. 

 

The main process of the Software Development Life Cycle is as follows: 

        According to the process of SDLC, we gather information on client requirements. Then we design the software accordingly and provide the design to the developer to develop. Now, a QA person comes in the role to test that particular developed software. When QA provides a green signal to go with that software, means QA test the whole developed software, and now we can deploy that software in a live environment. So in the next step Deployment is a process where QA finalize that, "Now software can go on the production side to go live". 
      In conclusion, software testing is a crucial aspect of software development that helps to ensure that the software meets the specified requirements and works as intended. By choosing the right testing tools and techniques and having a well-defined test plan, software testing can help to improve software quality, performance, and security, and provide a better user experience.
