There is a difference between the two terms and the roles of people working in these domains. Software testing is the activity that the project team performs to verify if the product is deliverable according to the client's standards. On the other hand, quality assurance is about planning and verifying the quality of the entire product development process, from requirement gathering to product delivery. Some of the key differences between the two are as follows: Quality Assurance Software Testing It is an elaborate process that works parallel to product development right from the beginning. Every step gets planned and monitored well to ensure the product succeeds, one phase after the other. It is a phase or an activity in the development process. Under this, the experts check the quality of the product under question. Experts only check if the product deliverables match the client requirements, and if it stands tall on the user needs, it gets to be in the market. It is a preventive method where the experts work to avoid any situation that may delay the product delivery. Moreover, they also work to ensure that the quality standards get met and that there are no scopes of revisions that might waste resources. It is a corrective measure to ensure that the product meets the user’s requirements. It doesn’t include any check related to the process followed for development or the resources used. The experts only check the end product and decide whether it goes for revision or is apt for delivery. It has the process as the highlight as the entire process is under supervision. From correct requirement gathering to development processes and end product testing. It has a product as the highlight, as the only concern of the team working in software testing is verifying the product for perfection. There is no mention of the process followed or resource utilization. The primary objective is to ensure the software, or the product developed is of the best quality. It also ensures the appropriate use of resources for organizational benefit. The primary objective is to find bugs or flaws in the end product until it is ready for delivery. The bugs go back for revision to the development team and the process continues till it is ready for delivery.
