Only through a good QA Plan can you determine how and in what order each aspect of a website should be tested. A good QA Plan injects testing into every aspect of an e-commerce project. This allows you to detect defects early, close to the point of insertion, thus defects won’t infect work later on.
Don’t underestimate the value of a good quality assurance plan. And, don’t skip this step. Not only must you execute a quality assurance test prior to launch, but also after you make any type of enhancement to your site.
