All people periodically make mistakes, so software products also contain defects, as a result of this. However, the use of appropriate testing techniques by qualified testers can reduce their number:
- Engaging testers to review software requirements and to refine user stories helps eliminate defects from these work products. This allows you to avoid unintentionally creating incorrectly functioning or untestable parts of the software during its development.
- Having testers work closely with system designers in the process of developing the system allows to improve its understanding and ensure that it can be fully tested. This reduces the risk of making fundamental mistakes in the development of the system.
- The close work of testers with developers allows you to increase the understanding of how all parts of the system work and how to test them. This reduces the risk of defects in the code and tests.
- Testing and validating the software before release allows you to eliminate defects that might otherwise be missed. This increases the degree of compliance with the agreed requirements and user needs.
