Testing and Deployment
Just before you deploy the website to a server after the development, there should be a sequence of rigorous, meticulous, and repeated tests to prove the elimination of bugs. The quality assurance team tests for functionality, usability, compatibility, performance, and so on. You must have a well functioning site.
Everything must run smoothly without a glitch. The development team must test all the scripts, ensuring that the site loads and displays perfectly on all devices and platforms. The importance here is to prove that the website is market-ready and can be released. Comprehensive testing reveals future improvements that can be made to upgrade the website.
Lastly, depending on the use of the website, a development team may need to include some fine-tuning details. This is to optimize its functionality and performance. This final touch might include plugin installations, on-page Search Engine Optimization, and page speed optimization.
