In the current age, the traditional waterfall model is slowly becoming obsolete, paving the way for Agile and DevOps. Previously, the testing phase was kept to be executed in the end, and often, when the deadline came closer, testing was done in a hurry, leaving many critical bugs in the open stage. This resulted in a buggy application that required frequent maintenance, missed certain critical business requirements, and resulted in the user’s discomfort.
However, in the current Agile age, testers, stakeholders, and developers work hand in hand, ensuring that every user story delivered fully satisfies the business requirements. Also, testing is divided into multiple phases such as accessibility testing, cross-browser testing, performance testing, usability testing, regression testing, and many more. Priority is not on the delivery of the product, but the delivery of a flawless product.
