What testing methodologies are adopted while performing Maintenance Testing?

Maintenance testing is a system done on various things including software and equipment. However, it does perform the same thing which is to see what is not working correctly. There are three different levels that can be performed and they are the system level, equipment level and the component level. There is a set of requirements that the object or equipment is supposed to do and if they don’t then a maintenance testing should be done first to determine what is not working.

During the performance of the maintenance testing, there are two testing methodologies that are adopted. These are called the breadth test and depth test. The breadth test refers to the testing that is done on an equipment in general and does not look at the details.
