What is software testing

 

 How does software testing works? 

  Software testing is a crucial process in the software development life cycle (SDLC) that ensures the 

  quality, reliability, and performance of software systems. The main objective of testing is to identify defects,        bugs, and errors in the software and ensure that it meets the specified requirements and performs as                  expected. Here's a general overview of how software testing works:

  1. Test Planning: The first step is to create a comprehensive test plan that outlines the testing               

       objectives, scope, approach, resources required, and timelines. 

  2. Test Design: In this phase, the test cases and test scenarios are designed based on the test plan. 

  3. Test Environment Setup: A dedicated test environment is set up that closely resembles the                       production environment where the software will ultimately be deployed. 

 4. Test Execution: The actual testing process begins by executing the designed test cases and                          scenarios. Testers interact with the software, input various data, and verify if the actual outputs match the            expected results. 

 5. Defect Reporting and Tracking: When defects or bugs are discovered during testing, they are              documented in a defect tracking system or bug tracking tool.

 6. Regression Testing: Whenever changes are made to the software, either due to bug fixes or new                features, regression testing is performed. 

 7. Test Reporting: Testers prepare test reports summarizing the testing activities, test coverage, test                 results, and any issues encountered during the testing process. 

 8. Test Completion and Sign-off: Once the testing objectives are met, and the software meets the             required quality standards, a test completion report is prepared, and the testing team provides formal sign-        off, indicating that the software is ready for release.

  It's important to note that the actual testing process may vary depending on the development methodology        (e.g., waterfall, agile) and specific project requirements. Additionally, organizations may have their own testing    frameworks, methodologies, and tools to support the testing process.
