An enterprise must deploy skilled QA professionals to get the quality of its software assesses thoroughly and effectively. But it can always accelerate the software testing process by making the programmers and testers work together. The developers can further assess the quality of application code by performing unit testing and integration testing throughout the coding process. Likewise, they must perform sanity testing to ensure that the software is functioning according to predefined requirements. Agile methodology further requires enterprises to unify software development and testing activities to deliver high quality software applications. The project management approach requires businesses to test the software continuously by a team consisting both programmers and testers.The conventional waterfall model allows business to start the software testing process after completing the software development process. But the conventional software streamlivve testing model does not meet the requirements of complex and cross-platform software applications. 

A steady increase is being noted in the number of enterprises switching from waterfall models to agile methodology and DevOps. As mentioned earlier, agile methodology required businesses to test the software continuously, along with making the programmers and testers work as a single team. Likewise, DevOps requires businesses to unify software development, testing, and deployment processes. Hence, the testers nowadays start testing an application from the initial phase of the software development lifecycle.Many entrepreneurs still believe that the only task of a testing professional is to find bugs or defects in an application. The even do not consider software testing requires skill and creativity. The misconception often makes businesses get their software tested by random people.

An enterprise can involve real users in the software testing process to assess the application's usability and user experience more effectively. But it must deploy skilled testers to get the software evaluated under varying user conditions and environments. The skilled testers understand how to identify the defects and performance issues in the software by creating many test scenarios. The even produce elaborate test results to facilitate the decision making process.Software development companies dedicate a substantial amount of resources and manpower for the development of applications according to requirements specified by enterprises or individuals. However, subsequent to development of such applications/software, companies are required to ensure that such software/applications perform in accordance with the client's requirements.
