Each day in the life of a QA Tester is different and being a QA means you never stop learning. Whenever you’re testing you have to act in different user roles.
QA Testing helps you in fixing the errors before they become major issues. That is why it’s important to get testing done as soon as possible. Don’t let yourself have additional costs, which come while replacing, retesting as well as reselling products, having errors. Software development consists of many stages and if bugs are caught in the earlier stages it costs much less to fix them. The bigger your organisation is, the bigger is the business impact of one bug.
