ISTQB CTFL-Foundation Exam With Confidence Using Practice Dumps

Maintenance testing is typically triggered by changes to the operational system, such as data migration, system modification, or system retirement. These triggers require testing to ensure that the changes do not negatively impact the existing functionality. However, the introduction of a test management tool does not directly affect the operational system and is not considered a trigger for maintenance testing​​.

Early test design can prevent fault multiplication, find faults, and cause changes to the requirements. The ISTQB CTFL syllabus v4.0 explains that starting test design early in the lifecycle helps to identify defects sooner, which can prevent the propagation of defects into later stages and reduce the overall cost of fixing them. While it can influence the requirements, it does not necessarily take more effort, and faults found early are typically less expensive to fix than those found later​​.

A disadvantage of independent testing is that developers might lose a sense of responsibility for the quality of their work. When developers rely too much on independent testers to find defects, they may become less diligent in their own testing and quality assurance efforts. The ISTQB CTFL Syllabus points out that while independent testing can provide an unbiased perspective and identify defects that might be missed by developers, it can also lead to potential downsides such as diminished developer accountability​​.
