Good quality can be defined as the successful completion of a project developed without a bug while meeting the needs of prospective users within a planned schedule and budget. “QA” stands for quality assurance. It refers to the task of performing various tests and inspections prior to the launch of a product in order to ensure that the service or product has achieved its objectives and can be used without problem.
In testing, both normal and abnormal use cases are carried out to identify defects. This ‘Detection’ activity is basic and ongoing. The goal of a QA effort varies from finding bugs to finding out whether a user is achieving what he or she intended, identifying potential serious issues in advance, and verifying whether any subsequent modifications were properly applied. Continuous ‘Detection’ activities can minimize problems and risks in advance and can lead to the good user experience. Most efficient QA activities have a significant impact on the overall schedule and development costs of the project. The completion of the QA process is an integral part of the completion of the entire project.
Why does a bug occur?
- Miscommunication or No communication: Poor communication can cause a bug. Therefore, clear communication must be recorded on a document.
- Software complexity: Whether it could be a flawed design or just a feature of a complex system, this requires more time to analyze and requires stress testing the complex modules.
- Programming errors: Nobody can develop a 100% error-free program.
- Changing requirements: The most common cause of issues are due to changes in requirements; simple changes in requirements can affect an entire whole system.
It is difficult for developers to verify everything objectively. After the occurrence of a bug, it may often difficult to organically reproduce and detect its actual source. This makes schedule management difficult because of the impact on development and associated modification work. Note, however, that the impact does depend on the situation and the scale of a project. It is, however, a burden on developers to carry out a project in a situation where time is limited. This can actually reduce the efficiency of the development. Therefore, testing of technical issues and functional risks through a separate testing team can be a great complement to the development environment and to overall project management
