Visual Testing:

Because most testing methods require the technician to examine the surface of the part being inspected, visual inspection is integral to many other nondestructive test methods. As the name implies, visual testing (VT) consists of visually observing a test object's surface to detect and evaluate surface discontinuities. VT can be performed by direct viewing—using line-of-sight vision—or by remote viewing with optical aids such as borescopes, fiberscopes, and computer-assisted imaging systems.
