Software Testing Scenario

Software testing is any activity aimed at evaluating an attribute and capability of a program. System and determining that it meets its required results. Although crucial to software quality and widely deployed by programmers and testers, software testing still remains an art, due to limited understanding of the principles of software. Testing and test designs parts of quality assurance should also focus on bug prevention. Bug prevention is testing fist goal. A prevented bug is better than a detected and corrected bug because if the bug is prevented, there's no code to correct. The difficulty in software testing stems from the complexity of software: we can not completely test a program with moderate complexity. Testing is more than just debugging. The purpose of testing can be quality assurance, verification and validation, or reliability estimation. Testing can be used as a generic metric as well. Correctness testing and reliability testing are two major areas of testing. Software testing is a trade-off between budget, time and quality.
