When the development of an application is in process, it is ok that the system has many defects. Software bugs appear all the time, especially during smoke testing, new feature testing, functional testing, unit testing or integration testing.
When software bugs are found, it is necessary to determine their nature and the reason of their appearance. It is better to do it without making changes in the system under test. For this purpose the project should operate in several modes.
As a Rule, a Project Operates in 2 Modes:
- Debug mode – it allows software testing company and development team to determine causes of the discovered errors appearance.
- Release mode – in this mode a project goes in production, there are no debugging-related elements in this version of an application.
There Are 3 Main Methods of Fixing Errors in an Application:
1. Real-Time Fixing
During this kind of fixing errors a tester uses debugging program that helps to inspect the system code when the discovered errors are being reproduced.
2. Code Examination
If a software bug is not very complicated it is possible to find out its cause by visual examination of the source code.
3. Using Defect Recording Mechanism or Defect Reports
If records are kept during mobile testing, desktop testing or web site testing, or there is detailed defect description, the developer can execute steps to reproduce the defect and discover the cause of the problem in the source code.
