Foundation Level CTFL-Foundation Reddit Questions

The cost of fixing a fault increases as the software progresses through the development lifecycle. Fixing defects identified early in the requirements or design phases is less expensive compared to fixing those found later in testing or after the software has been deployed. This is due to the larger impact on the system, more extensive rework required, and potential disruptions to the user experience in later stages.

The typical sequence of formal review activities includes planning, kick-off, individual preparation, and review meeting. The planning phase sets the scope and objectives, the kick-off initiates the review process, individual preparation involves participants reviewing the materials on their own, and then the review meeting is held to discuss the findings.

Maintenance testing is performed on an existing operational system that has undergone planned enhancements, corrections, or other modifications. The goal is to ensure that the changes have been implemented correctly and that the system continues to function as intended. This type of testing is not typically used for defect correction during development, user acceptance testing complaints, or the integration of functions in new system development​​.

Debugging is the process that developers follow to find, analyze, and fix the root causes of defects in the software. This includes identifying the source of the problem, correcting the code, and then testing the changes to ensure the defect has been properly fixed and that the fix does not introduce new issues.
