Developers sometimes think that tester is against them and that could produce problems. The software tester needs to convince the rest of the team that her/his part is really important and to have good communication with them and in a nice way prove them that he is not their opponent. Tester plays on the same team, just with different duties.
The tester provides if the team builds the correct product and if so, are the team building it correctly. A person in this role is someone who consistently questions all parts of the process to ensure the team is producing the desired output. Simply, software tester improves the quality of the user’s application.

The software tester primarily performs software testing procedures for software quality. They generally have a clear understanding of tools and techniques for testing software quality, with a certain level of knowledge and experience in software development.
