Why testing throughout the entire SDLC is important?

[Pavan]

In software companies, testing plays a crucial role for the quality of an application. Software testing throughout the entire SDLC (Software Development Life Cycle) generally happens in agile methodology. People who are still following traditional approach where testing is performed at the end of all development stages might be facing a lot of issues in an application. The importance of testing in SDLC is to improve functionality, performance and other quality attributes. Testing throughout the entire SDLC not only helps in early detection of defects, but it also helps in preventing them. It allows a company to reduce the time to release the product compared with the time taken in traditional methods. Customer might wait more time for software release, but they never like to work with buggy software.
